PURPOSE:To prevent a photoelectric conversion efficiency from decreasing by composing it of conductive paste containing molybdenum powder as the main ingredient and synthetic resin varnish as the binder. CONSTITUTION:An electrode material is composed of conductive paste containing molybdenum powder as the main ingredient and synthetic resin varnish as the binder. That is, a solar cell element in which a photodetecting side electrode 2 made of a transparent conductive material such as ITO, etc., a P-type amorphous film 3, an I-type amorphous film 4 and a N-type amorphous film 5 are sequentially formed on a glass substrate 1 is formed in a vacuum system. After the film 5 of the obtained element is coated with Mo conductive paste by a screen printing method, the paste is completely cured by heat treating to form a Mo thick film electrode 6. Thus, since the electrode for ohmic contact with the light transmission side of the cell is formed, the photoelectric conversion efficiency and environmental resistance of amorphous solar cell or II-VI compound semiconductor solar cell can be effectively enhanced. |
