Method of making solar cell module with improved weathering characteristics

摘要

A process for producing a solar cell module is characterized in that a grid electrode is formed having a coating comprising an epoxy resin of 20 g/m.sup.2 day0.1 mm/40 C.90%RH or less in moisture permeability which is disposed so as to cover the entire exposed exterior of said grid electrode. The solar cell module is free of short-circuits between the grid electrode and the lower electrode even upon repeated use under severe environmental conditions of high temperature and high humidity, and continuously exhibits a desirable photoelectric conversion efficiency over a long period of time.
