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 substantially the entire heterojunction of each cell to minimize the internal resistance of the cell and may conveniently protect the heterojunction from degrading environmental conditions. The conducting layer interconnects an exposed electrode region of one cell with the heterojunction forming material of the adjacent cell while remaining insulated from any intervening cell structure. In one embodiment, the uppermost conducting layer is lead, which seals the underlying materials from atmospheric constituents, such as oxygen and water vapor, while remaining relatively inert to such constituents.
