Four terminal perovskite-silicon PV tandem devices hit 30% efficiency
The conversion efficiency of tandem solar cells to beyond the limits of today’s commercial photovoltaic (PV) modules has been pushed further. For the first time four-terminal perovskite/silicon tandem devices with a certified top cell, have passed the barrier of 30%. Such high efficiency enables more power per square meters and less cost per kWh. The …
