Abstract: A photovoltaic device (10) includes an optically transparent, electrically conductive layer (22) and a second electrically conductive layer (13) both of which provide contact areas for electrodes. The photovoltaic device (10) consists of a plurality of at least two cells (11/12) in a tandem configuration. A first cell (11) may be made of an amorphous semiconductor and a second cell (12) may be made of two semiconductor layers (15/14) of different compounds having a heterojunction (16) therebetween. The amorphous semiconductor layer (21) of the one cell (11) has a surface which contacts the optically transparent, electrically conductive layer (22). One of the two semiconductor layers (14) of the second cell (12) has a surface which electrically contacts the second conductive layer (13). Means (18) for example a transparent, conductive layer, such as indium tin oxide, or a tunnel diode structure are provided to connect another surface of the first cell (11) and another surface to the second cell (12) so that the cells (11/12) are optically and electrically in series.
