    Abstract

    Combining perovskites with well-established photovoltaic materials such as silicon is an attractive option for producing cheap, high efficiency and high voltage solar cells. Perovskite/silicon tandems have the potential for further progress in increasing the efficiency to 30% and beyond. Here we discuss recent progress towards this goal. We demonstrate a 4-terminal tandem perovskite/silicon configuration in which the efficiency is as high as 27.7% through a passivation approach using 2D perovskites. We also demonstrate efficiency above 21% and fill factor of 83% for a 1cm2 single junction perovskite cell using a nanotextured electrode transport layer. We have further used perovskite/silicon tandems to achieve more than 17% solar-to-hydrogen efficiency. These results show the clear potential of perovskites in practical high efficiency devices.
