Perovskite solar cells (PSC)

There has been fast recent progress in perovskite solar cells (PSCs) towards low cost photovoltaic technology. Organometal mixed halide (MAPbX3 or FAPbX3) perovskites are the most promising light absorbing material sandwiched between the electron transport layer (ETL) and hole transport layer (HTL). These two layers play a critical role in boosting the power conversion efficiency (PCE) and maintaining air stability. Currently we are focusing on different forms of ABX3 type (i.e. MAPbI3, FAPbI3, MAPbBr3, CsPbI3 QDs) and its different composition for efficient perovskite solar cells

Phase-heterojunction all-inorganic perovskite solar cells surpassing 21.5% efficiency - Nature EnergyThe fabrication of perovskite heterojunctions is challenging. Mali et al. develop a heterojunction with two different crystalline phases of CsPbI3, achieving 21.5% and 18.4% efficiencies on small-area solar cells and 18 cm2 solar modules, respectively.
