PURPOSE:To enhance durability, efficiency, and reliability by a method wherein an insulating layer is built of a silicate and hardening agent on the surface of a metal substrate and, thereon, a rear-side electrode layer, an amorphous semiconductor layer, a transparent electrode layer, and a protecting film are formed, in that order. CONSTITUTION:On a stainless steel substrate 1, a layer of reactive inorganic coating agent, which is a mixture of a silicate and hardening agent, is formed by application, and the layer is subjected to drying and baking for the formation of an insulating layer 6. Such a silicate is represented by a general formula M2O.nSiO2, where M is one or more chosen out of lithium, sodium, potassium, cesium, tertiary amine, and quarternary ammonium. Such a hardening agent is composed of one or more chosen out of a metal, metal oxide, metal hydroxide, phosphate, silicate, and silicofluoride. Next, on the insulating layer 6, a rear-side electrode 2, amorphous semiconductor layer 3, transparent electrode 4, and a protective film 5 are built, in that order. This design improves on a semiconductor semiconductor solar battery in terms of durability, efficiency, and reliability. |
