A photovoltaic array module incorporating a plurality of photovoltaic cell strips (11). Each cell strip (11) incorporates an electrically conductive substrate layer (21), a semiconductor body (22) deposited on the substrate layer (21), and a transparent electrically conductive layer (23) deposited on the semiconductor body (22). Each cell strip (11) further incorporates a preformed thin-film unitary grid and interconnect structure (20) electrically associated with the transparent electrically conductive layer (23) thereof so as to collect and remove electrical current therefrom and electrically to interconnect the cell strips (11). A first busbar (12) and a second busbar (13) are connected to the end cell strips (11) of the array to collect the electrical energy generated thereby.
