Dye-Sensitized Photoconductivity and Photovoltaic Effect in Silicon

Mikhail A. Goryaev, Rene A. Castro

Abstract

In this paper we investigate the influence of organic dyes applied to the semiconductor surface on the effectiveness of the direct current photoconductivity of powdered silicon and photovoltaic effect in the monocrystalline silicon. Dyes on the semiconductor surface effectively increase the photoconductivity of powdered samples in the dye absorption band. The effectiveness of the monocrystal sensitization is smaller because the specific surface area of finely divided powders is several orders of magnitude larger than it is in monocrystals. The optimum concentrations of dye molecules on the semiconductor surface for the internal photo effect sensitization are determined. We also discuss the mechanism of the sensitization based on the theory of non-radiative resonant inductive energy transfer.
