Sharp Hits Solar Cell Efficiency Record of 43.5%

With all of the different types of solar cells being developed from thin-film to crystalline silicon as well as new ways of boosting light absorption it seems there is always a new solar cell efficiency record being announced, but this new record from Sharp of 43.5% is a pretty big deal. A large jump over the company's previous record of 36.9% efficiency in November 2011, it shows that solar technology is getting ever closer to that 50% mark that could revolutionize the industry. Sharp achieved the conversion efficiency record with their concentrator triple-junction compound solar cell that uses a lens-based system to focus sunlight on the cells to generate electricity. According to Sharp : Compound solar cells utilize photo-absorption layers made from compounds consisting of two or more elements, such as indium and gallium. The basic structure of this latest triple-juncti...
