Abstract

The effect of a magnetic field on the photocurrent I ph in Si and GaAs solar cells is investigated. It is shown that the observed change in the photocurrent I ph of the solar cells in response to a magnetic field can be caused by a decrease in the diffusion length of excitons L exc. A simplified model of the photomagnetic experiment is proposed to estimate the diffusion length of excitons L exc and the contribution made by excitons to the photocurrent of the solar cells.
