(72) FILI, Giovanni (SE) et LINDTRÖM, Henrik (SE) (73) EXEGER OPERATIONS AB, Box 55597, SE-102 04 STOCKHOLM (SE) (74) S.C.P. AKKUM AKKUM & Associates, No. 1777, Rue 6.261, Auditorium Jean Paul II, Quartier Mbankolo, B.P. 4966, YAOUNDE (CM). (57) The present invention relates to a solar cell (la) comprising a stack of porous layers, a support substrate (2) for supporting the stack, and a charge conducting medium (7) penetrating through the porous layers. The stack comprises a porous light-absorbing layer (3), a porous first conductive layer (4) including conductive material for extracting photo-generated electrons from the light-absorbing layer, a porous counter electrode (6) including conductive material, and a separating layer (5) made of porous electrically insulating material and arranged between the conductive layer (4) and the counter electrode (6), and where the conductive layer (4) is arranged closer to the light-absorbing layer (3) than the counter electrode (6). The support substrate (2) is porous, and the charge conducting medium (7) is penetrating through the support substrate (2).
