Future heterojunction technology (HJT) solar cells may require significantly less silver to produce, according to findings from researchers at the Fraunhofer Institute for Solar Energy Systems (ISE).
German solar testing house Fraunhofer ISE opened its new technology evaluation centre (Module-TEC) in a former Solar Fabrik factory in Freiburg, Germany this week.
Perovskite solar cell researcher Oxford PV and German research organisation Fraunhofer ISE have developed a full-sized tandem PV module with a record efficiency of 25%.
