Spontaneous solar water splitting with decoupling of light absorption and electrocatalysis using silicon back-buried junction
Abstract
The simultaneous management of optical, electrical, and catalytic properties is challenging for photoelectrochemical devices. Here, authors design Si back-buried junction photoelectrodes that can be series connected for unassisted water-splitting with a high solar-to-hydrogen efficiency of 15.62%.
