Tailoring Light Management in All‐Perovskite Tandem Solar Cells: The Impact of Nanotextures

open access: yesAdvanced Functional Materials, EarlyView.
To further improve the power conversion efficiency of all‐perovskite tandem solar cells, light management strategies need to be implemented. Front‐sided nanotextures reduce reflection losses, which boosts light absorption, thus increasing the tandem JSC, which is further supported by reducing parasitic absorption.
