Abstract:
1. A photovoltaic cell comprising: a first substrate having on its surface an electrode layer, said electrode layer having on its surface a semiconductor film on which a photosensitizer is adsorbed, and a second substrate having on its surface an electrode layer, said first substrate and said second substrate arranged so that the electrode layer overlaid with the semiconductor film and the electrode layer on the second substrate are opposite to each other with an electrolyte sealed between the semiconductor film and the electrode layer on the second substrate, wherein spacer particles are spread in locations positioned across a plane interposed between the semiconductor film and the electrode layer on the second substrate thereby uniformizing a gap between the semiconductor film and the electrode layer on the second substrate, and wherein at least one of the electrode-layer-having substrates is transparent.
