Perovskite-based solar cells have made tremendous progress over the last decade achieving outstanding lab-scale efficiencies of 24.2% early 2019 in single-junction architecture and to an astonishing 28% in tandem (perovskite associated with crystalline silicon), turning it into the fastest-advancing solar technology to date.
Scientists at Solliance (Eindhoven, The Netherlands), in collaboration with MiaSole Hi-Tech Corp., fabricated a flexible solar cell with a record breaking power conversion efficiency of 21.5%. The solar cell combines two thin-film solar cell technologies into a 4 terminal tandem solar cell stack: a top flexible semi-transparent perovskite solar cell with a bottom flexible copper indium gallium selenide (CIGS) cell.
The solar technology company Midsummer (Stockholm Sweden), recently received an order from US solar panel manufacturer Sunflare worth over US$7M for production equipment of thin film solar cells. The production equipment will be delivered to a new factory in China.
