Abstract

The photocurrent in a selenium photovoltaic cell varies with time even if constant conditions be maintained. This variation consists either in a decrease or an increase of current, the current approaching a constant value in the course of about ten minutes. Whether the initial change of current is a decrease or an increase seems to be independent of the particular type of cell but is determined by the wave-length of the incident radiation and possibly also in certain cases by the temperature of the cell. If the cell is exposed to light from incandescent lamps, the effect is dependent on the temperature and will vanish at a certain temperature. The phenomenon is not an effect of fatigue; a more suitable name for it would be “initial effect.”
