Four terminal perovskite-silicon PV tandem devices hit 30% efficiency

TNO, TU Eindhoven, imec and TU Delft, partners in Solliance, joined forces to further push the conversion efficiency of tandem solar cells to beyond the limits of today's commercial photovoltaic (PV) modules. For the first time, four-terminal perovskite/silicon tandem devices with a certified top cell passed the barrier of 30%. Such high efficiency enables more power per square meter and less cost per kWh. The result is presented during the 8th World Conference on Photovoltaic Energy Conversion (WCPEC-8) in Milan, and it has been achieved by combining the emerging perovskite solar cell with conventional silicon solar cell technologies. The perovskite cell, which features transparent contacts and is part of the tandem stack, has been independently certified.
