Abstract
Large area, thin-film body of photovoltaic material is subdivided into a plurality of small area devices. Through a selective etching process, a portion of the bottom electrode of each small area device is exposed. A metallic contact member is deposited upon the exposed portion of the electrode and a series connection between adjoining cells is established by interconnecting the metallic contact member of a first cell with the top electrode of an adjoining cell, so as to provide a large-area photovoltaic device including a plurality of interconnected sub-cells.
