Low‐Cost Strategy for High‐Efficiency Bifacial Perovskite/c‐Si Tandem Solar Cells

Tandem Solar Cells In article number 2100781, Wenzhong Shen and co-workers have proposed and proven that bifacial perovskite/c-Si tandem solar cells can not only improve the energy output, but also significantly reduce the Si thickness while maintaining the high efficiency. The photovoltaic performance of bifacial perovskite/c-Si tandem solar cells combining existing large-scale preparation technologies, was also optimized.
