Abstract

Abstract : Device architectures for semi‐transparent perovskite solar cells are proposed that are not only highly efficient but also very effective in thermal‐mirror operation. With the optimal top transparent electrode design based on thin metal layer capped with a high‐index dielectric layer for selective transmittance in visible and high reflectance in near‐infrared (NIR) region, the proposed see‐through devices exhibit average power conversion efficiency as large as 13.3% and outstanding NIR rejection of 85.5%, demonstrating their great potential for ideal "energy‐generating and heat‐rejecting" solar windows that can make a smart use of solar energy. Abstract : An efficiency of 13.3% with an outstanding total solar energy rejection ratio of 89.6% is realized in semi‐transparent perovskite solar cells. With the optimal top electrode design leading to a selective transmittance in visible and high reflectance in the near‐infrared region, the proposed see‐through device demonstrates the noteworthy potential for ideal "energy‐generating and heat‐rejecting" solar windows that can make smart use of solar energy.
