Abstract:
The present invention relates to a solar cell and a method of producing the same. The solar cell comprises a porous light absorbing layer (1), a first porous conducting layer (2), a second conducting layer (3), a porous substrate (4) between the conducting layers, the porous substrate comprises a catalytic conducting portion (4a) in electrical contact with the second conducting layer and an insulating portion (4b) between the first porous conducting layer (2) and the conducting portion, and a conducting medium (5) for transporting charges between the conducting portion (4a) and the light absorbing layer (1). The conducting medium is located in the light absorbing layer (1), the first porous conducting layer (2), and partly the porous substrate (4) so that the insulating portion (4b) and a first part (4a′) of the conducting portion (4a) comprises the conducting medium and a second part (4a″) of the conducting portion is free of conducting medium.
