PURPOSE:To improve appearance, to enhance water resistance and to elevate reliability by screen-printing an epoxy resin, the molecular weight of a principal ingredient of which extends over 2000-3000, to a naked CdS/CdTe photovoltaic element and thermally treating the photosensor for two hr at 120 deg.C. CONSTITUTION:A CdTe sintered film 3 is formed onto a CdS sintered film 2, and a carbon film 4 is shaped onto the sintered film 3. AgIn films 5, 6 as ohmic electrodes are each formed onto the sintered film 2 and the carbon film 4. An epoxy resin, the molecular weight of a principal ingredient of which extends over 2000-3000, is screen-printed to an element acquired in this manner, and thermally treated for two hr at 120 deg.C. Accordingly, appearance is improved, water resistance is enhanced and reliability can be elevated. |
