Abstract
The present invention relates to a photovoltaic device (1). The device comprises a solar cell unit (2) comprising a porous light-absorbing layer (3) at a top side (2a), of a porous first conducting layer (4), a porous substrate (5) of an insulating material. The solar cell unit comprises a conducting medium. The photovoltaic device comprises a first conductor (7) in electrical contact with the first conducting layer (4), a second conductor (8) in electrical contact with the second conducting layer (6), and an encapsulation (9) encapsulating the solar cell unit. The encapsulation comprises a top sheet (9a) and a bottom sheet (9b). The first and second conductors (7, 8) are arranged between the encapsulation (9) and the solar cell unit (2) at the bottom side (2b) of the solar cell unit (2). The second conductor (8) is arranged between the second conducting layer (6) and the bottom sheet (9b) of the encapsulation (9), and the first conductor (7) is arranged between the porous substrate (5) and the bottom sheet (9b). The first conductor (7) is electrically insulated from the second conducting layer (6). A part (14) of the porous substrate (5) comprises conducting material (12) disposed…
