Enhanced Hydrogen Evolution under Simulated Sunlight from Neutral Electrolytes on (ZnSe)0.85 (CuIn0.7 Ga0.3 Se2 )0.15 Photocathodes Prepared by a Bilayer Method.

Abstract

A (ZnSe)0.85 (CuIn0.7 Ga0.3 Se2 )0.15 photocathode with a bilayer structure was fabricated and found to exhibit a photocurrent almost twice that of a photocathode with a monolayer structure during hydrogen evolution from water. The cathodic photocurrent reached maximum values of 12 and 4.9 mA cm-2 at 0 and 0.6 VRHE in a neutral phosphate buffer under… (More)
