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.

摘要： Disclosed is a method for growing a thin film, which includes modifying a surface grain size and surface roughness on a thin film to improve the mobility of a carrier and a light scattering effect. The method for growing a thin film includes: forming nuclei of grains having various grain orientations on a substrate; causing first grains having a first specific grain orientation to grow predominantly among the grains having various grain orientations, thereby forming a first preferred texture comprised of the predominantly grown first grains; and then causing second grains having a second grain orientation to grow predominantly, thereby forming a second preferred texture comprised of the predominantly grown second grains, wherein the surface grain size of each of the second grains forming the second texture is larger than that of each of the first grains forming the first texture.
