1. A dye-sensitized solar cell module (1) comprising
a porous insulation substrate (7) forming a porous network and at least two dye-sensitized solar cell units (2a-c) arranged adjacent to each other and connected in series, each cell unit including:
a working electrode (3),a first porous conducting layer (4) for extracting photo-generated electrons from the working electrode (3) and formed on one side of and in direct physical contact with the porous insulating substrate (7),a counter electrode (5) including a second porous conducting layer formed on an opposite side of and in direct physical contact with the porous insulating substrate (7),an electrolyte permeating said porous network for transferring electrons from the counter electrode (5) to the working electrode (3), anda series connecting element (6) for electrically connecting the counter electrode (5) to the working electrode (3) located in an adjacent cell unit, wherein the series connecting element (6) is a third porous conducting layer comprising a plurality of conducting particles penetrating through said porous network of the porous insulating substrate (7) and forming an electrical path from an upper side to a lower side of the porous insulating substrate (7) and disposed to electrically interconnect the first porous conducting layer (4) of one of the cell units and the second conducting layer (5) of the adjacent cell unit, and each of the cell units is surrounded by an ion barrier (12) in the form of a non-porous layer penetrating through the porous insulating substrate (7) to prevent the electrolyte from leaking to an adjacent cell unit. |
