A solar module made by the sequential stacking of a conducting metal oxide layer, an amorphous semiconductor layer, a back metal electrode, and a passivating resin layer on a transparent substrate, in which the passivating resin layer includes a water vapor barrier layer having a permeability to water vapor of not more than 1 g/m.sup.2 day measured at a thickness of 100 .mu.m, with the water vapor barrier layer being a polymer having a backbone consisting essentially of carbon and hydrogen. This barrier layer prevents the oxidation of the back metal electrode by water vapor, so that the stability of the module is improved in outdoor use.
