Abstract

The turn-off character in a-Si:H solar cells has been studied by rectangular monochromatic light pulses. It is found that the turn-off time increases obviously with the decrease of the excitation light wavelengths when the turn-off steady photovoltages are the same. This phenomenon can be explained by the wavelength dependence of the photocapacitance and the time constant products RC in the a-Si:H solar cells.
