PURPOSE:To manufacture the solar cell inexpensively by a method wherein a melocyanine color film having direct-chain-form alkyl is formed into an N type semiconductor substrate of P-N junction and this is provided with an electrode. CONSTITUTION:A metal evaporation film 1 is provided on the back surface of the N type semiconductor substrate 2 (e.g. Si single crystal), while the melocyanine color film 3 expressed by the formula is formed on the side of the front surface of the substrate by the method of vacuum evaporation, spraying or the like, and thereby P-N junction is prepared. By forming a translucent metal film 4 on the color film 3 of the P-N junction semiconductor through vacuum evaporation, the solar cell having excellent characteristic is obtained. Since the cell can be formed by such a simple process, the cost therefor can be reduced. |
