PURPOSE: To obtain a thin film solar battery capable of even application causing no winding reform at all while enhancing the mechanical strength by a method wherein a weatherproofing resin layer is formed by coating and drying step with fluorine resin solution between a bonding layer used for covering the surface of a thin film solar battery with the weatherproofing layer is manufactured in the incident light side using a glass fiber. CONSTITUTION: A thin film solar battery has a photoelectric conversion semiconductor layer 3 held between the first electrode layer 2 and the second electrode layer 4 on a flexible substrate 1 and both surfaces thereof are covered with weatherproofing resin layers 7, 72 through the intermediary of a bonding agent layers 6, 62. Since the thin solar battery is mounted on the surface in the incident light side in the case of application, the incident side bonding agent 6 is reinforced by coating or mixing a glass fiber to enhance the mechanical strength. Otherwise, the weatherproofing resin layer 7 on the surface is thinly formed by coating and drying up with a solution of weatherproofing fluorine resin solution. Through these procedures, the weatherproofing resin layer 7 on the surface is evenly applied causing no winding reform at all even if this layer 7 is wound up in roll. |
