▎ 摘　　要

NOVELTY - An ultra-thin quasi-solid-sensitized battery comprises electrode pair, an anode, an electrolyte, and porous copper zinc tin sulfide/graphene composites as counter electrode, where the electrolyte has reduced thickness is 1-2 mu m, standard solid electrolyte reduces the thickness of the anode to improve the quasi-solid electrolyte contacting the anode and the light absorption of the dye, and improves the photoelectric conversion efficiency of the battery. USE - Ultra-thin quasi-solid-sensitized battery. ADVANTAGE - The battery has improved photoelectric conversion efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing ultra-thin quasi-solid-sensitized battery.
