Enhancement of the photoelectrochemical properties of a CuGaSe2-based photocathode for water reduction induced by loading of a Cu-deficient layer at the p–n heterointerface

Photoelectrochemical activity for water reduction (H2 liberation) over a co-evaporated CuGaSe2 compact thin film modified with a CdS layer and Pt deposits under simulated sunlight (AM 1.5G) radiation was evaluated, specifically focusing on the impact of a Cu-deficient layer (CDL) loaded on the top p...
