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.
Meyer Burger Technology Ltd (Thun, Switzerland) recently announced that it will sell its photovoltaic and specialised materials (e.g. semiconductor and sapphire glass industries) wafering equipment and service business to Precision Surfacing Solutions (PSS) (formerly Lapmaster Wolters Ltd), a global supplier of equipment and services for surface enhancement technology. As part of the transaction, significant parts of Meyer Burger’s current production facilities in Thun as well as around 100 employees involved in the wafering technology portfolio in Thun and the relevant service locations worldwide will also be transferred to PSS.
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.
