ABSTRACT:
A photovoltaic device which is resistant to shunt and short circuit defects developing between the opposed electrodes thereof. The photovoltaic device comprises an electrically conductive substrate, a semiconductor body including a photogenerative region, a layer of transparent conductive material, and means for collecting photogenerated current. In particular, a layer of low-conductivity material is operatively positioned between the layer of transparent conductive material and the collecting means, thereby resistively restricting the flow of electric current through short circuit portions. A method of fabricating such a shunt-resistant photovoltaic device is also disclosed.
