Abstract
An object of the present invention is to provide a photovoltaic cell that demonstrates a superior photoelectric conversion function. The present invention relates to a photovoltaic cell comprising a semiconductor electrode, an electrolyte and a counter electrode, wherein (1) the semiconductor electrode contains an oxide semiconductor layer having photocatalytic activity, (2) the oxide semiconductor layer contains secondary particles in which primary particles comprising a metal oxide are aggregated, (3) the average particle diameter of the primary particles is from 1 nm to 50 nm, and the average particle diameter of the secondary particles is from 100 nm to 10 μm, and (4) the photovoltaic cell generates electromotive force by radiating light of a wavelength substantially equal to the average particle diameter of the secondary particles onto the semiconductor electrode.
