Perovskite solar cells are susceptible to severe reverse bias challenges beyond those of traditional silicon cells, which may represent further impediments to the technology’s commercialisation, according to new research.
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”.
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.
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.
