The Future of Perovskite Solar Cells

Silicon solar panels have been in use for nearly 50 years. Since their inception in the mid-20th century, the efficiency of silicone solar has increased from 2% to around 20% (with the highest-end models reaching efficiencies of almost 30%) and cost of production has plunged nearly 98%.

Still, the future of solar energy may not be in silicon at all. Silicon carries a heavy environmental impact, and though it has become more affordable, its fabrication remains expensive relative to other energy sources.

In 2009, researchers in Japan developed a different type of solar cell using a crystalline material called perovskite. Once it was recognized for its impressive light absorption and charge transport properties, perovskite quickly gained ground as a promising material for solar cell research.

Paired with a layer of lead or tin halide, perovskite cells have already exceeded the efficiencies of leading silicon cells by about 4%. One company, the UK-based Oxford PV, has even announced the development of perovskite cells that can convert as much as 37% of the sunlight they absorb into light.

The efficiency of perovskite solar isn’t the only thing about it that holds promise. Perovskites, unlike rigid silicone solar panels, can be painted or sprayed almost anywhere, creating the potential for a type of ‘solar paint’ from the realms of speculative science fiction.

Like silicon solar cells, perovskite cells consist of several of thin films. Thus, researchers have successfully adapted the equipment used in solar cell production and research, including pulsed-DC magnetron sputtering and thermal evaporation systems, as perovskite equipment.

The production of perovskite solar cells is precise, expensive, and still subject to much experimentation. Every variable, from deposition rate to gas pressure, must be carefully controlled and calibrated. Current perovskite equipment set-ups range from small evaporators with a single deposition chamber to multi-chambered clusters. Though researchers have made strides in the replicability of these systems, they are not yet equipped for the mass production.

It would be an understatement to say that researchers are excited about perovskites. Billions in investments have poured into the industry in recent years, and many are pointing to perovskites as the solution to the world’s growing energy crisis. However, there is still much to be done before perovskite solar technology reaches the point at which it is ready for mass commercialization.

Still, the rapid progress in perovskite research in the past decade has researchers hopeful that the technology could one day stand alongside silicon as a viable renewable energy solution.

5 Tips To Enhance Your Mental Health Each Day

Mental health is considerably more than a diagnosis. It’s generally speaking mental prosperity. It is the manner in which you feel about yourself as well as other people and in addition your capacity to deal with your sentiments and manage regular troubles.

Make arrangements with steady relatives and companions, or search out activities where you can meet new individuals, for example, a club, class or care group.

  1. Figure out how to manage stress

Like it or not, the pressure is a piece of life. Practice great adapting abilities such as do martial arts, work out, take a nature walk, play with your pet, or attempt diary composing as a stress reducer. Additionally, make sure to grin and see the silliness throughout everyday life. Research demonstrates that giggling can support your invulnerable framework, ease torment, loosen up your body and lessen the pressure.

  1. Make time to calm your mind

Unwinding activities and praying can enhance your perspective and point of view. Truth be told, contemplation may enable you to feel quiet and upgrade the impacts of being calm.

  1. Set reasonable objectives

Is Tennis for You?

Do you like fast-paced sports that give you a great workout? Tennis is a wonderful way to stay in shape and build muscle. The recent release of the movie BATTLE OF THE SEXES (which depicts the legendary tennis match between Billie Jean King and Bobby Riggs) has helped to propel the sport into a whole new arena, but tennis hardly needs extra publicity. It’s already enjoyed by millions worldwide every day on both indoor and outdoor courts. Still need convincing? Here are just a few of the things that make tennis great:

Bone Health

As we age, our bones become more and more brittle which is why falls can be so dangerous for elderly people. A simple spill for a healthy adult can lead to a broken hip (and even death) for a senior. Tennis is wonderful for building bone health because it helps to increase bone strength.

Burns Calories

Want an exercise where you’re really making use of your body? Tennis is for you! You are constantly moving your legs and swinging your arms, building muscle mass in both and burning calories. Dedicated tennis players can run between 3-5 miles per match and burn 400-600 calories an hour.

Aerobic and Anaerobic Health

You intake a great deal of oxygen while playing tennis and that is very beneficial for oxygen and nutrient delivery to your bones. The blood flow to your muscles also increases, improving function. The stop/start nature of a tennis game makes it very high energy. Cardiovascular health is crucial for preventing such dangers as heart attack and stroke.

It’s Very Social

Sure you can use the backstop and play by yourself, but tennis is a very social sport out of necessity: there has to be at least 1-3 other people on the court. Regular tennis players soon bond and their friendship often carries over into other parts of life.

Summer Camp Planning

Enjoying A Summer’s Day

If you’re planning to hold a summer camp, or if you’re the camp’s coordinator, you need to have a good deal of action prepared.

  • The location needs to be finalized
  • You have to plan whether the summer camp is going to be an overnight program or a day time program
  • If it is an overnight program, then thousands of things have to take into consideration
  • Right from accommodation, to the daily meals, everything needs to be taken care of

If you’re planning a day time program, then the transportation service needs to be hired, volunteers are required, and what not. Moreover, the amount to be collected from participants needs to be worked out. Once you settle down with planning such fiscal and administrative details, it’s time for some real action.

Children look forward to attending summer camps. They want to enjoy, learn new things, and make new friends! So, your summer camp planning decides whether the kids are going to enjoy it or not. You want to put all your creative and fun quotient into making this summer camp the most memorable ever for the participants. A few factors listed below can ensure grand success of your summer camp:

Summer Camp Themes

When you plan a summer camp, you ought to get a theme. A summer camp theme will brief the participants as to what the camp is going to be like. You can have a swimming summer camp, for example. If you’re planning a bunch of games, you could call it ‘adventure land’ or something like that. Moreover, an art camp would have a theme like ‘paint the world,’ and so on.

Summer Camp Games

If the summer camp is going to be an overnight program, you have to keep the kids occupied with various activities, other than the main one (the theme). Plan interesting and fun games. You can have a scavenger hunt, sack race, relays, and so on. Games act as one of the most effective and simple relaxing techniques for kids. They also help them gel with others and develop an ability to function in a team.

Allot Free Time

Kids in summer camp need to be on their own at least part of the time. This period may be used to make new friends, or explore oneself. You could even encourage them to write down their thoughts about the summer camp, or maintain a diary about the daily activities. Care should be taken not to forcefully ask them to do certain things; let them be on their own.


When you plan a summer camp program, counselors and doctors ought to be there. A kid could feel homesick or depressed if he isn’t doing well at the camp. A doctor or a counselor can make the kid feel comfortable during such times. Counselors can also play a significant role in studying the behavioral patterns of the kids, thus helping the organizers bring out the best in a child and enhance the quality of the summer camp.

Selecting a summer camp depends on the type of the child taking part. If a kid has never attended a summer camp, he or she may be reluctant to go for more than a week.

A Special Day

Your summer camp program can have a specific day, such as a cultural or talent day. A talent day, for example, would mean every child has to exhibit the talent they possess, like playing the guitar, singing, painting, or dance.

Art Day

How about planning for an art day? Children can be taught origami, painting, drawing, and pottery. You could even have the camp decorated or organize an exhibition to exhibit the various crafts made by your kids.

Adventure Sports

The most interesting portion of a summer camp is adventure sports! Plan for sports like rock climbing, river crossing, snorkeling, parasailing, etc. Make sure you don’t force a child to carry out an activity he or she is scared of. However, encouraging words to boost the kid’s morale are always welcome. Even better, provide them with the possibility of undertaking the task with an adult as this might imbue confidence.

Science and Nature

You can devote a day or two to science and nature activities. Conduct certain experiments or go around the camp location finding the scientific names of trees. Wordplay is a good idea as it is both educational and entertaining. Moreover, if a fun element is associated with certain things, kids tend to remember them faster.

In the meantime, this clip from the ’70s comedy classic MEATBALLS demonstrates what you should not do when it comes to summer camp planning:

David Gilmour Live At Pompeii

In 2015 David Gilmour set out to play a series of concerts in historic venues across the world. In 2016 he became the first performer to play the amphitheater in Pompeii in front of a live audience since the gladiators in 79AD.

On July 7th & 8th 2016, Gilmour preformed two  shows at the legendary Pompeii Amphitheater in the shadow of Mount Vesuvius. The concerts were the first ever rock performances played to an audience in the ancient Roman amphitheater, which was built in 90BC and entombed in ash when Mt Vesuvius erupted in 79 AD. David Gilmour is the only performer to play to an audience in the arena since the time of the gladiators, almost 2,000 years ago.

The concert performance film, David Gilmour Live at Pompeii, was shot in 4k by director Gavin Elder  and includes highlights from both shows. The concert is a spectacular audio-visual experience, featuring the famous huge circular cyclorama screen as well as lasers, pyrotechnics and stellar performances from an all-star band.

Stories from the Factory- What I learned Working


When working with new environments, there are several things that we must consider: your employees must know about WHMIS, and have a strong background knowledge of the WHMIS signs and what they indicate. What to do in the event of an incident, emergency, or even in the event of a loss of an employee. There are jobs, such as those in the oil industry, that are deemed inherently dangerous jobs. Some deaths are a result of not following procedure, not using tags, etc. There are many inherently dangerous jobs out there such as being an astronaut, or president of the united states. Statistically, President of the United states is one of the most murdered professions.

Recently, there has been a shift to online based workplace training- it is cheaper and more efficently than person to person training. Most companies today are using online based training because it is generally cheaper and quicker. Employees get a good sense of the type of issues they may face, as well as safety precautions and disaster mitigation. I was recently doing WHMIS training online  for a project I was working on in a factory setting, I went through it in about 3 hours and felt at the end that I was better off with the up to date, online based educational learning.
Many companies are not up to date on their training for JHSC certifications, this is a major problem. It only takes one circumstance, one issue, one loss to result in major and massive financial and legal repercussions. Here are a couple stories about people who have not had their certifications up to date. One individual was working as a contractor, doing construction on a second floor of a home. Some wood broke and the individual fell a story down to the concrete floor below, sustaining serious head injuries. Falls are the most common workplace risk.

Another individual fell into a silo, and was suffocated by the grain dust. This would have been an awful way to die and easily prevented if there was stronger more stringent health codes in effect.

Health And Safety Concerns

This is Pipe coming at you, and I want YOU to know how I can change our community for the better. There are many changes I would make to our community to make it more beneficial for the people in our community. This includes helping people repair damaged homes. We need our entire community to help each other in rebuilding and repairing damaged homes, and the government needs to provide more funding for us. We also need to clean up the streets and whatever trash is around the neighbourhood.


We need to ensure that our kids are getting the best that they can in order to succeed. This means more funding to schools around the area for different social activities, sports, and arts. We also need to make sure that the jobs we are working is providing a safe environment. This means that firms and companies need to provide proper training and information for whichever activity is required.

The more training we have as a community, the more we can advance and succeed. I believe that I can make those changes happen. With your help, we can make this community better and brighter than it is now.
