SOLAR BATTERY AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To improve reliability of a solar battery which has high performance and is excellent in mass-productivity, and provide the solar battery at a low cost. SOLUTION: In this solar battery, a lower electrode 4, a photoelectric converting layer 5 and a transparent substrate 6 are arranged in this order on the surface of a metal substrate 2, and an insulating layer 3 exists between the metal substrate 2 and the lower electrode 4. Main component of the insulating layer 3 is silicon oxide. Thermal expansion coefficient of the insulating layer 3 at 30 to 250 deg.C is 0.1 to 5 times that of the metal substrate 2 at 30 to 250 deg.C.
