Why Perovskite Solar Cells are the Most Promising Advancement in Solar Technology to Date

Recently, a renewable energy technology developer in the U.K. made a remarkable announcement. Oxford PV claims its researchers have engineered perovskite solar cells that exceed the efficiency record for this technology just a year ago, reaching an energy conversion efficiency of 27.3%.

The company is aiming to have the cells on the market by the year 2020.

But that’s not all: Oxford PV also says it hopes to breach the 30% efficiency mark soon using combined silicon-perovskite solar cells that work in tandem. That would be an incredible feat, given that this technology only reached 3.8% efficiency just ten years ago.

Some experts are calling perovskite the most promising advancement in solar cell technology to date — one that could, with the help of thin film lithium-ion battery technology, transform the market for renewable energy.

So, what’s behind the hype?

What Are Perovskite Solar Cells?

Perovskite is a naturally-occurring calcium titanium oxide material with an amazing ability to absorb light. Synthetic versions of the mineral have incredible photovoltaic capabilities.

Until recently, perovskite was relatively unknown within the renewable energy conversation. Many people first became aware of it through a TED Talk that shone a light on it in 2016.

In addition to its excellent light absorption, perovskite is remarkable in that it can be manufactured from polycrystalline materials through solution processing: a method that is comparatively low-cost next to other methods of producing photovoltaic solar cells. Affordability has long held back the solar technology industry, and perovskite has the potential to turn the tide on that part of the issue.

The Promise of Perovskite and Thin Film Lithium-Ion Batteries

With its efficiency and affordability, perovskite solar cells have the potential to become a scalable renewable technology — if researchers can overcome its weaknesses.

One such disadvantage is shared by all photovoltaic solar power: unpredictability. Without the ability to control the climate, our capability of generating solar energy is limited by the whims of the local weather conditions.

Thin film lithium-ion battery technology is increasingly seen as a solution to this solar problem, since it makes it possible to store surplus energy on favourable days for use on days where the weather is uncooperative. The fact that this tech has advanced rapidly in tandem with perovskites is highly promising.

The second challenge to perovskite solar cells is stability and longevity. In general, perovskite is susceptible to degrade when subject to high humidity and UV rays; it must be engineered with other materials to increase its ability to withstand those conditions.

Much of Oxford PV’s current research involves enhancing the long-term stability of perovskite solar technology. Currently, the developer’s tech can withstand temperatures of up to 200 degrees Celsius, which is a vast improvement over earlier design.

5 Statistics on Workplace Drug and Alcohol Use in Canada

Is drug and alcohol use a problem in Canadian workplaces? The following statistics on workplace drug and alcohol use in Canada, gathered by Drivercheck (http://www.drivercheck.ca/), illustrate the extent of the issue.

1. 47% of Industrial Injuries Can Be Linked to Alcohol Consumption

The effects of alcohol impairment can result in accidents in industrial workplaces, which can have potentially fatal consequences. According to Q3 Innovations, a company that works with the US Department of Labour, nearly 40% of industrial fatalities and 47% of industrial injuries can be linked to alcohol consumption and alcoholism.

2. Workplace Drug and Alcohol Use Costs Businesses more than $2.8 Billion in Alberta

Not only is there a human cost to workplace drug and alcohol use, but it takes an enormous economic toll as well. The Alberta Health Services reports that on-the-job drug and alcohol use costs businesses more than $2.8 billion in that province alone.

In addition to lost time accidents, the loss is attributed to increased absenteeism, higher workers’ compensation costs, insurance costs, reduced morale, and emotional problems.

3. 41% of Drivers Treated for Accident Trauma Test Positive for Drugs

A study by the Canadian Centre on Substance Abuse looked at the rates of drug and alcohol use by drivers who were treated for trauma following a collision. It was found that 41% of drivers tested positive for drugs and 35% were positive for alcohol.

4. In the Oil and Gas Industry, Employees Seeking Treatment for Alcohol Abuse Rose 481%

Shepell-faj, a research group, examined health and wellness trends in the Canadian oil and gas sector. One alarming statistic uncovered was the fact that the number of oil and gas workers seeking treatment for alcohol abuse through Employee Assistance Programs rose by 481% over a three-year period.

While it is positive that employees are pursuing treatment, the sharp rise in requests is notable.

5. Workplace Injuries Drop 51% After Introducing Drug Testing

Using injury rates as a way to measure the effectiveness of drug testing, one study found that the average company that drug tests sees its injury rate decrease by 51% within two years of implementation.

In another study, 79% of employers in Alberta reported that testing has either been “very” or “somewhat” successful in reducing workplace problems due to alcohol. For drug testing, 87.3% of employers found it had a positive effect.

Some Insight On Cognitive Ability

Willis and associates released the 5-year results in JAMA last December and the results were really positive. All 3 kinds of cognitive programs were shown to have an impact right away after the program, after 3 years, and after 5. The results of the group that used a computer-based program to train processing speed revealed clear short-term and long-lasting results. Individuals who experienced enhanced speed of processing likewise revealed much better performance on jobs of important activities of day-to-day living such as quickly discovering a product on a congested kitchen shelf and reading medication bottles. They also reacted to road signs faster. We discovered this transfer of training in our prior studies using the training method too. 

Simply put, significant portions of the participants improved their memory, information-processing and reasoning speed throughout all 3 methods. The most impressive outcome was that, when checked 5 years later, the participants in the computer-based program had less of a decline in the skill they were trained in than did a control group that received no cognitive training. 

To respond to the very first question, I would state that a crossword puzzle is not a form of cognitive training. It can be promoting, however it is not a type of structured psychological exercise that has been shown to improve certain cognitive skills – besides the ability of doing crossword puzzles, of course. 

In terms of the second question, it is too early to say whether we can actually reverse decline in a permanent method. There are lots of skills included and the studies are not long enough to really compare various trajectories. What we can say is that by doing some workouts, one can enhance cognitive speed of processing by 146-250 %, and that a significant portion of that improvement remains even after 5 years. We can not state more definitively.

Preventative Measures For Health And Safety

safe

We here at Shared Global are always looking for ways to improve health standards from every day living to workplace safety to better health insurance rates.  We strive to do everything we can to ensure the safety of all individuals and one of those ways is to provide information on preventative measures for health and safety especially in the workplace.  Throughout current years, we’ve found that the stats for workplace safety have gotten worse.  There’s been more accidents and negligent actions that have resulted in devastating consequences, and we truly believe most of these accidents could have been prevented if the right information was in place.  For example, with proper heights training, we could prevent injuries while working at heights for all employees of companies.  This can be easily taught in a classroom where there are no distractions.  When provided with the proper, accurate training, there should be no room for negligent mistakes.  Accidents like falling from a dangerous height can be prevented when the right safety features are in place and taught to employees.

Many employees do not know that they may ask for proper training when they feel there is not enough information on the tasks at hand.  Many workers don’t fully take advantage of their rights in a company.  For example, many workers don’t know about worker’s compensation and the viable options when an accident occurs.  Employers should also know fully what they can do to provide the best environment for their workers.  Employers can’t control an earthquake hitting their building, but they can control the building environment and safety features.  Employers can also control the amount of knowledge their workers have in these types of situations.  If you need more information, check out the schedule of training and classes for JHSC for classes and online workshops to enhance workplace safety.  We cannot stress the importance of improving workplace standards so that accidents and mistakes can be prevented.  The first step in preventing workplace accidents is to place preventative measures for health and safety.
