PURPOSE:To obtain a battery of large area which has less power loss and does not decrease conversion efficiency by coating a thin transparent conductive film on a transparent insulating substrate when forming the transparent electrode with metal wirings for forming a solar battery, and forming the metal wirings of the prescribed pattern. CONSTITUTION:A thin transparent conductive film 11 made of tin oxide, indium oxide, titanium oxide or zinc oxide is coated on a transparent insulating substrate 13 made of glass, or plastic, and formed in the state that metal wirings 12 of the prescribed pattern are contacted thereon. At this time the wirings 12 may be formed on the film 11, or formed between the film 11 and the substrate 13. Or, only the wirings 12 of the film 11 is reduced electrolytically or thermally depositing in hydrogen gas stream, and the portion may be used as wirings 12. Thereafter, an amorphous silicon having a pin junction is accumulated on the substrate 13, and a back surface electrode is formed on the upper surface. Thus, a solar battery of large area is obtained with good workability. |
