Highly efficient counter electrode for dye-sensitized solar cell and method of producing the same
European Patent EP1646059
Disclosed herein is a counter electrode for a dye-sensitized solar cell, and a method of producing the same. In the dye-sensitized solar cell includes a photoelectrode (10) containing a photosensitive dye molecules. The counter electrode (20) is positioned opposite to the photoelectrode (10), and an electrolytic solution (30) interposed between the photoelectrode (10) and the counter electrode (20). The counter electrode (20) has an electron transfer layer. The electron transfer layer has a structure in which one or more conductive materials, selected from the group consisting of a conductive polymer, platinum nanoparticles, a carbon compound, inorganic oxide particles, and a conductive polymer blend, are sequentially laminated. In the counter electrode (20), the electron transfer layer promotes smooth electron transfer through an interface between the electrolyte, containing pairs of redox ions, and counter electrode (20). Thereby, energy conversion efficiency is significantly improved in comparison with a conventional dye-sensitized solar cell employing a counter electrode in which only a platinum layer is applied on a transparent conductive material.

PCT No. PCT/SE96/00177 Sec. 371 Date Oct. 31, 1997 Sec. 102(e) Date Oct. 31, 1997 PCT Filed Feb. 12, 1996 PCT Pub. No. WO96/25730 PCT Pub. Date Aug. 22, 1996A solar cell driven display is provided with battery backup, where the included components, solar cell and/or battery forms an integrated system based on porous titanium dioxide or other metal oxide films. The solar cell charges the battery and/or operates as a power source for the display. The solar cell and battery as display each include a pair of film electrodes on, for example, glass. They are interconnected by an electrolyte, which brings about charges between the paired electrodes. The solar cell is of a photoelectrochemical type and the battery of a rocking-chair type. By intercalation, for example, by lithium ions in the oxide film it is colored, for example, titanium dioxide becomes blue. Then it may simultaneously operate as a display portion but also as a portion in an electrochemical element of a battery. The solar cell may operate directly with the oxide as a photoactive electrode, titanium dioxide being active in the UV range, but the oxide may also be coloring matter sensitized to absorb light in the visible wavelength range. The display portion may also be provided with coloring matter, which upon reception or emission of electrons changes color.

European Patent EP0333641
Abstract of corresponding document: US4927721
The regenerative photo-electrochemical cell comprises a polycrystalline metal oxide semiconductor layer having a substantially monomolecular chromophore layer in a surface zone. The surface of the metal oxide semiconductor layer has a roughness factor of more than 20, preferably more than 200. Photo-electrochemical cells having such metal oxide semiconductors have good monochromatic efficiency using redox systems with iodides or bromides.
