Scientists have set a new efficiency record for a single-junction perovskite solar cell at 25.6%. The cell additionally showed operational stability for 450 hours, and intense electroluminescence with external quantum efficiencies of more than 10%.
A numercal study by researchers at India’s Chitkara University has shown enhanced charge extraction in metal-perovskite-metal back-contact solar cell structure through electrostatic doping. The proposed design yielded a 59.4% improvement in power conversion efficiency over previously reported structures.
India’s Ministry of New and Renewable Energy is funding the research to develop high-efficiency crystalline silicon solar cells, including those with passivated emitter and rear contact structure, and perovskites.
Low-cost batteries and novel perovskite materials are among the topics selected for joint research and development.
