Title:
SOLAR BATTERY ELEMENT
Document Type and Number:
Japanese Patent JPS59188979
Kind Code:
A
Abstract:
PURPOSE:To increase the battery current by a method wherein a metallic oxide film provided on the light receiving surface of the titled element is made of an oxide film mixed with titanium oxide and tin oxide. CONSTITUTION:The mixed film of titanium oxide and tin oxide is formed on the light receiving surface of a single crystal Si substrate 3 having P-N junction by sputtering method. The wt% of the tin oxide should be 10-80%. Next, said mixed film of the electrode forming part is removed by etching, and bus bar electrodes 1 and finger electrodes 2 are formed at the part by vapor deposition method. By forming such a metallic oxide film, the increase of current can be made 40% or more compared with the case of no formation of the oxide film.
