    摘要: A solar cell includes a substrate, a barrier layer on the substrate, a back electrode layer on the barrier layer, a light absorption layer on the back electrode layer, a buffer layer on the light absorption layer, and a transparent electrode layer on the buffer layer. The barrier layer is selectively formed on the substrate. The substrate may include alkali elements. Accordingly, since alkali elements may be uniformly distributed in the light absorption layer, the efficiency of the solar cell may be improved.

    摘要: In order to manufacture a CIS-based thin film solar cell that can achieve high photoelectric conversion efficiency by adding an alkali element to a light absorbing layer easily and with good controllability, a backside electrode layer (2) is formed on a substrate (1). Then, a p-type CIS-based light absorbing layer (3) is formed on backside electrode layer (2), and then an n-type transparent and electroconductive film (5) is formed on this p-type CIS-based light absorbing layer (3). At this time, the backside electrode layer (2) is constituted by forming a first electrode layer (21) using a backside electrode material in which an alkali metal is mixed and, then forming a second electrode layer (22) using the backside electrode material that does not substantially contain the alkali metal.
