Abstract: PURPOSE: A Se or S system thin film solar cell and a manufacturing method thereof are provided to improve photoelectric transformation efficiency of a solar battery by controlling preferred orientation of a light absorption layer through the bulk porosity adjustment of a preferred orientation control layer. CONSTITUTION: A back contact electrode(120) is formed on a substrate(110). The back contact electrode is composed of a double layer of a first back contact electrode(121) and a second back contact electrode(122). A preferred orientation control layer(130) is formed on the back contact electrode. A light absorption layer(140) is formed on the preferred orientation control layer. A window layer(150) is formed on the light absorption layer. A transparent electrode layer(160) is formed on the window layer.

Abstract: PURPOSE: A thin film solar cell and a method for manufacturing the same are provided to form an electrode surface layer including a large amount of oxygen in the back electrode, and to secure the stability of the back electrode in a high temperature. CONSTITUTION: A thin film solar cell includes a substrate, a back electrode(20), a light absorption layer(40), and an electrode surface layer(30). The back electrode is formed on the substrate. The light absorption layer is formed on the back electrode and includes selenium or sulfur. The electrode surface layer is formed between the back electrode and the light absorption layer. The electrode surface layer includes oxygen for controlling the diffusion of sodium from the back electrode to the light absorption layer.
