Abstract
A method to prevent short-circuits or shunts in a large area thin film solar cell comprises applying, to a substrate with a first conductive electrical contact, at least one first layer comprising a p-type or n-type conductive layer and a second layer comprising an n-type or p-type conductive layer or a Schottky barrier layer. The second layer, in turn, is provided with a second conductive electrical contact. Those areas of the first conductive electrical contact which are effectively uncovered by the first layer are passivated after forming the first layer and before application of the second layer.
