Abstract
Abstract
The photo-generated currents of GaAs solar cells with different lengths of space charge region are obtained and analyzed in this study. The enhanced absorption coefficient in the space charge region is adopted to calculate the photo-generated current based on the solar cell physics theory. The calculated currents coincide well with the experimental currents both under single wavelength incidence and solar spectrum irradiation conditions.
