The Fraunhofer Institute for Solar Energy Systems ISE has reported a new record efficiency of 25.9 percent for a III-V/Si tandem solar cell grown directly on silicon. This cell was produced on a low-cost silicon substrate for the first time – marking an important milestone on the way to economical solutions for tandem photovoltaics.
The development of next generation solar power technology that has potential to be used as a flexible ‘skin’ over hard surfaces has moved a step closer, thanks to a significant breakthrough at The University of Queensland (UQ) in Australia.
The Daegu Gyeongbuk Institute of Science and Technology (DGIST) in South Korea reported that the team led by Dr. Jin-Kyu Kang at DGIST’s Division of Energy achieved 11.4% for the photoelectric conversion efficiency of flexible CZTSSe thin-film solar cells, the highest in the world.
Ontario-based manufacturer of solar photovoltaic modules and provider of solar energy solutions Canadian Solar announced its technology team set a world record of 22.80% conversion efficiency for p-type large area multi-crystalline silicon solar cell.
