摘要：
An optically transparent cathode was developed for use in dye-sensitized solar cells. Fluorine-doped tin oxide conducting glass modified with a monolayer of cis-dichloro-bis(4,4'-dicarboxy-2,2'-bipyridine)osmium(II) efficiently reduces the oxidized form of the redox mediator. This transparent cathode transmits light that is not absorbed by the dyed TiO2; consequently, more than one cell can operate in optical tandem (i.e., stacked). Two types of stacked cells are considered: one where both photoanodes are dyed with the same dye and one where the photoanodes are dyed with different, spectrally complementary dyes. Overall behavior of these tandem cells is compared with single-cell analogs.
