Researchers at Europe’s largest solar research institute, Fraunhofer Institute for Solar Energy Systems, claim to have developed the world’s most efficient silicon-perovskite tandem solar module in an industrial format.
The team used tandem solar cells from Oxford PV and adapted existing facilities in Fraunhofer ISE’s “Module-TEC” production laboratory. The result is a 1.68 square metre module with 421 watts and a 25% efficiency rate, outperforming any silicon photovoltaic module in an industrial format. The perovskite-silicon solar cells, with a 26.8% efficiency rate, were manufactured by Oxford PV in Brandenburg. The low-temperature processes used for interconnection and encapsulation are suitable for mass production and can be implemented in commercial facilities. The team plans to certify the photovoltaic module, focusing on long-term stability testing. Oxford PV aims to commence commercial production of tandem solar cells this year, considering the newly developed module a significant milestone in demonstrating the record-breaking performance of their tandem solar cells.
