The invention provides a photoelectric transducer of high photoelectric efficiency, which includes a transparent substrate with transparent conductor film, a reflection control film, and a photoelectric unit. A reflection control film contains particles having a mean particle size of 0.01 to 1.0 micrometer and includes irregularities in the surface, which are derived from the presence of the particles. The glass plate with transparent conductor film has a transmittance greater than 75% in a wavelength range of 800 nm to 900 nm. The photoelectric unit includes a photoelectric layer with a band gap below 1.85 eV.
