Revealing Trapped Carrier Dynamics at Buried Interfaces in Perovskite Solar Cells via Infrared-Modulated Action Spectroscopy with Surface Photovoltage Detection
{{output}}
Interfacial engineering is a proven strategy to enhance the efficiency of perovskite solar cells (PeSCs) by controlling surface electronic defects and carrier trapping. The trap states at the "top" interface between the perovskite and upper charge extraction... ...
