Abstract
The present invention relates to a dye-sensitized solar cell unit (1″) comprising a working electrode comprising a light-absorbing layer (10), a porous first conducting layer (12′) for extracting photo-generated electrons from the light-absorbing layer (10), wherein the light-absorbing layer (10) is arranged on top of the first conducting layer (12′), a porous insulating layer (105c) made of an insulating material, wherein the porous first conducting layer (12′) is arranged on top of the porous insulating layer (105c). The dye-sensitized solar cell unit (1″) further comprises a counter electrode comprising a second conducting layer (16) including conducting material, and a porous third conducting layer (106c) disposed between the porous insulating layer (105c) and the second conducting layer (16), and in electrical contact with the second conducting layer. The dye-sensitized solar cell unit (1″) further comprises a liquid electrolyte for transferring charges between the counter electrode and the working electrode. The second conducting layer (16) is non-catalytic and the third conducting layer (106c) comprises catalytic particles (107″) for improving the transfer of electrons to th…
