ABSTRACT:
A photovoltaic device having a tab soldered onto it for modularization, includes a first conductivity type crystalline semiconductor layer, a collector electrode electrically connected to the tab by soldering, a short-preventing layer formed under a soldered portion of the collector electrode, and a second, opposite conductivity type amorphous semiconductor layer formed above the crystalline semiconductor layer. The short-preventing layer is an insulating layer of SiO.sub.2 or the like, or an opposite conductivity type doped layer formed in the first conductivity type crystalline semiconductor layer.
