| Research Abstract |
The improvement of the efficiency in converting the sunlight into electricity and the use of inexpensive cell parts are necessary to reduce product costs of dye-sensitized solar cells (DSSCs). For resolving these issues, we carried out studies as follows: (1) Technical development of bilayer working electrodes, which constructed porous titanium dioxide overlayers with voids as ion path on nanoporous titanium dioxide underlayers. (2) Technical development of tandem type DSSCs, which consist of the top layer adsorbed by terpyridine complex dye (black dye) and the bottom layer adsorbed by bipyridine complex dye (N719). (3) Technical development of counter electrodes, which consist of platinum-substitute carbon layer. A 9% efficient DSSC with an aperture area of 50 mm square was fabricated from the first and second techical developments.
