Abstract
An improved photovoltaic device exhibiting increased tolerance of shorting and shunting defects includes: a substrate having a semiconductor body disposed thereupon, a current collecting structure such as a bus-grid structure disposed upon the semiconductor body and a transparent conductive electrode overlying the semiconductor body and the current collecting structure. The photovoltaic device may also include a layer of low electrical conductivity material disposed beneath at least portions of the current collecting structure to prevent electrical contact between said structure and defective regions of the device occuring therebelow. Also disclosed are methods for the fabrication of the improved device.
