Isolation layer for photovoltaic device and method of producing same
Large area photovoltaic devices are defined by applying a pattern of electrically-insulating material directly atop the exposed surface of the semiconductor material. Methods of producing these photovoltaic devices in a continuous or batch process are also disclosed herein. Each large area device may include a matrix of electrically-isolated segments, each segment including a common substrate, a semiconductor body atop the substrate, and a transparent, electrically-conductive coating atop the semiconductor layer. Each large area photovoltaic device may include additionally or independently thereof, an electrically-inactive region also defined by the insulating material. The instant method of producing the photovoltaic devices eliminates the scribing steps required by prior art processes, while the product includes a boundary which separates the adjacent, electrically-isolated segments.
