Axitec expands solar panel capacity to 2 GW
Module manufacturer Axitec is ramping up its production capacity in China, India and Vietnam to meet growing demand for PV modules in Germany, Austria and Switzerland.
China’s polysilicon imports fell by 23% in 2022, says Bernreuter Research
After an interim high in 2021, polysilicon imports into China fell again in 2022, but the country’s share in global output still came close to 90%, according to a new report by Bernreuter Research.
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.
