Perovskite Solar Cell achieves world efficiency record, Researchers hope to hit 26% soon
Australian Centre for Advanced Photovoltaics (ACAP) has announced that its team at UNSW achieved a breakthrough in procuring highest efficiency rating with the largest perovskite solar cell. As compared to traditional silicon solar cells, Perovskite solar cells are flexible, cheaper, easier to produce and make, and can even be sprayed on surfaces. The team recorded 12.1 percent efficiency rate with a 16 centimeter square Perovskite solar cell, which is 10 times bigger than the current certified high-efficiency perovskite solar cell. The achievement was also confirmed by the international testing centre Newport Corp, in Bozeman, Montana.
The researchers are pretty much sure that they can achieve an high-efficiency to upto 26 percent in couple of years through further research. The team also recorded an 18 percent efficiency rating on a 1.2 centimeter square cell.
This is a very hot area of research, with many teams competing to advance photovoltaic design. Perovskite came out of nowhere in 2009, with an efficiency rating of 3.8%, and have since grown in leaps and bounds. These results place UNSW amongst the best groups in the world producing state-of-art high-performance Perovskite solar cells. And I think we can get to 24% within a year or so.
said Anita Ho-Baillie, a senior research fellow at the Australian Centre for Advanced Photovoltaics (ACAP), while speaking at the Asia-Pacific Solar Research Conference in Canberra on December 2, 2016.
The news holds a great importance considering demand of better, more efficient solar cells to meet renewable energy demands. Moreover, the Perovskite solar cells have their own benefits as compared to traditional silicon-based photovoltaics.
The versatility of solution deposition of Perovskite makes it possible to spray-coat, print or paint on solar cells. The diversity of chemical compositions also allows cells be transparent, or made of different colours. Imagine being able to cover every surface of buildings, devices and cars with solar cells,
further explained Ho-Baillie.
The only issue that the researchers need to deal with is that Perovskite cells are prone to fluctuating temperatures and moisture. Current version of these cells isn’t durable and lasts only for a month or two. But the team is sure that it’ll come out with a solution to deliver more sustainable model.
However, that doesn’t make the current technology altogether disadvantageous. Rather, these kind of cells can be used in disposable accessories and variety of other solutions used in emergencies like natural disaster to provide temporary relief.
