Dye-sensitized solar cell including a porous insulation substrate and a method for producing the porous insulation substrate

摘要

The present invention relates to a dye-sensitized solar cell including a working electrode (1), a first conducting layer (3) for extracting photo-generated electrons from the working electrode, a porous insulation substrate (4) made of a microfibers, wherein the first conducting layer is a porous conducting layer formed on one side of the porous insulation substrate, a counter electrode including a second conducting layer (2) arranged on the opposite side of the porous substrate, and electrolyte for transferring electrons from the counter electrode to the working electrode. The porous insulation substrate comprises a layer (5) of woven microfibers and a layer (6) of non-woven microfibers disposed on the layer of woven microfibers. The present invention also relates to a method for producing a dye-sensitized solar cell.
