High‐Efficiency Perovskite/Silicon Tandem Solar Cells with Flexibility

Tandem Solar Cells In article number 2400899 , Ryousuke Ishikawa and co‐workers develop flexible perovskite/silicon tandem solar cells by fabricating perovskite cells on thin, bendable silicon substrates. By optimizing surface microtexturing and processing, an efficiency of 26.5% was achieved. These findings suggest that flexible, high‐efficiency solar cells could be deployed in situations where traditional silicon cells are not practical.
