Abstract
An array of photovoltaic cells in a back wall-type configuration supported by a rigid transparent vitreous substrate, such as glass, for admitting incident radiation to the cells. A plurality of cells are interconnected into a desired electrical configuration by one or more layers of electrically conducting materials which overlie the entire heterojunction of each cell to minimize the internal resistance of the cell and may conveniently protect the heterojunction from degrading environmental conditions. Various component layers forming the photovoltaic cells are selectively removed and strips of insulating material are applied prior to forming the heterojunction. The electrically conductive material is thereafter applied and separated at areas protected by insulating material. The resulting series array contains no exposed heterojunction areas, thereby obtaining improved operating stability and performance.
