Inverted perovskite solar cell achieves 23.9% efficiency, high durability
A US-Canadian group of scientists has used Lewis base molecules to improve surface passivation in a perovskite solar cell. The team produced a device with a high open-circuit voltage and remarkable stability levels.
Emmvee starts building new solar cell and module line
Karnataka-based Emmvee Group is constructing a 1.5 GW cell line with integrated 1.75 GW module capacity in Karnataka. The new facility will expand its overall module capacity to 3 GW.
Perovskite-CIGS tandem solar cell design promises 29.7% efficiency
A numerical study by researchers at India’s Chitkara University shows enhanced performance in the top device of a tandem solar cell based on copper indium gallium selenide (CIGS). The design had a higher open-circuit voltage, with the top cell acting as a current-limiting cell.
