Abstract

A compound-based thin film solar cell which has a high photovoltaic conversion efficiency is obtained. The compound-based thin film solar cell is provided with substrate (), back surface electrode layer () formed on substrate (), p-type light absorption layer () formed on back surface electrode layer (), n-type high resistance buffer layer () formed on p-type light absorption layer (), and ZnO film () formed on n-type high resistance buffer layer (), where n-type high resistance buffer layer () includes a first buffer layer (A) formed on the p-type light absorption layer () and a second buffer layer (B) formed on the first buffer layer (A) and where the second buffer layer (B) is formed by a material which has a lattice constant closer to the lattice constant of the ZnO film () than the first buffer layer (A).
