摘要：
Provided is a Se- or S-based thin film solar cell, including a substrate, a rear electrode formed on the substrate, a light absorbing layer formed on the rear electrode and containing at least one of selenium (Se) and sulfur (S), and an rear electrode top layer. The rear electrode top layer is formed between the rear electrode and the light absorbing layer, and contains a large amount of oxygen (O) to control diffusion of sodium (Na) through the rear electrode to the light absorbing layer. In this manner, it is possible to improve the electrical conductivity and interfacial adhesion of the rear electrode while stimulating diffusion of sodium (Na) to improve the efficiency of a thin film solar cell.
