Bi₂ S₃ -Cu₃ BiS₃ Mixed Phase Interlayer for High-Performance Cu₃ BiS₃ -Photocathode for 2.33% Unassisted Solar Water Splitting Efficiency.

ABSTRACT: To realize practical solar hydrogen production, a low-cost photocathode with high photocurrent density and onset potential should be developed. Herein, an efficient and stable overall photoelectrochemical tandem cell is developed with a Cu₃ BiS₃ -based photocathode. By exploiting the crystallographic similarities between Bi₂ S₃ and Cu₃ BiS₃ , a one-step solution process with two sulfur sources is used to prepare the Bi₂ S₃ -Cu₃ BiS₃ blended interlayer. The elongated Bi₂ S₃ -Cu₃ BiS₃ mixed-phase 1D nanorods atop a planar Cu₃ BiS₃ film enable a high photocurrent density of 7.8 mA cm^-2 at 0 V versus the rever
