Solar cell module with improved weathering characteristics

摘要

An improved solar cell characterized in that the grid electrode has a coat comprising an epoxy resin of 20 g/m2.day.0.1 mm/40 DEG 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 occurrence of shortcircuit 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.
