High‐Performance Flexible All‐Perovskite Tandem Solar Cells with Reduced VOC‐Deficit in Wide‐Bandgap Subcell (Adv. Energy Mater. 45/2022). Issue 45 (1st December 2022) - Lai, Huagui
Abstract : Perovskite Solar Cells In article number 2202438, Cong Chen, Dewei Zhao, Fan Fu, and co‐workers report 15.1% flexible near‐infrared transparent wide‐bandgap (1.77 eV) perovskite solar cells with a low open‐circuit voltage–deficit of 480 mV. When paired with flexible, narrow‐bandgap (1.24 eV) perovskite solar cells, they demonstrate a 23.8% flexible all‐perovskite tandem solar cell with a superior open‐circuit voltage of 2.1 V.
