Perovskite-on-silicon PV modules are more environmentally advantageous than conventional silicon heterojunction (HJT) modules over a 25-year lifetime, according to a study from researchers in Germany.
Researchers at EPFL’s Photovoltaics and Thin Film Electronics Laboratory and CSEM’s Sustainable Energy Centre have claimed an efficiency of over 30% for perovskite-on-silicon-tandem solar cells, establishing “two world records”.
Thin-film technologies such as cadmium telluride and perovskites can markedly reduce the carbon intensity of PV compared with silicon alternatives, according to researchers at the US National Renewable Energy Laboratory (NREL).
Researchers at the US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) have found that a tin-lead perovskite cell can overcome problems with stability and improve efficiency, with their latest experiment yielding a 25.5% conversion efficiency.
US perovskite company Tandem PV has closed on the first half of a US$12 million Series A raise after raising US$6 million for building a pilot manufacturing facility in its headquarters of San Jose, California.
Battery storage manufacturer NGK Insulators has invested in EneCoat Technologies, a spin-out of Kyoto University involved in the development of of perovskite solar cells.
The chemical process of halogen bonding has “considerable potential for the development of a new generation of solar cells based on perovskites”, according to researchers at the Polytechnic University of Milan.
Researchers in Saudi Arabia have reported the “the first ever” successful damp-heat test of perovskite solar cells, which they claim has moved the technology closer towards commercial viability after it withstood 1,000 hours of harsh conditions and maintained a 95% efficiency.
