PHOTOELECTRIC TRANSDUCER, PROCESS FOR PRODUCING THE SAME, AND PHOTOVOLTAIC APPARATUS

WIPO Patent Application WO/2007/043533

A1

This invention provides a photoelectric transducer (1) comprising a light transparent substrate (2), a light transparent conductive layer (3) provided on the light transparent substrate (2) and a porous semiconductor layer (5) provided on the light transparent conductive layer (3). The porous semiconductor layer (5) can adsorb coloring matter (4) and contains an electrolyte (6). The photoelectric transducer (1) further comprises a porous spacer layer (7) containing an electrolyte (6) provided on the porous semiconductor layer (5) and a counter electrode layer (8) provided on the porous spacer layer (7). According to the above constitution, the thickness of the electrolyte layer is determined by the thickness of the spacer layer containing the electrolyte (6) unlike the prior art technique in which the thickness of the electrolyte layer is determined by spacing between two substrates. Accordingly, the electrolyte layer can be formed thinly and evenly and can enhance the photoelectric conversion efficiency and the reliability.
