Abstract
The effect of wavelength on the photocurrent and photovoltage of a vertical parallel junction solar cell under steady state condition was theoretically analyzed. Based on the diffusion equation, the excess minority carrier’s density is expressed; both photocurrent density and photovoltage determine the junction recombination velocity and the wavelengths. The excess minority carrier density, the photocurrent density, and the photovoltage were calculated and plotted. The objective of this work is to show the effects of solar cell junction recombination velocity and the wavelengths on these electrical parameters. We have shown the effect of wavelength on initiating the short-circuit (Sfsc) and limited the open circuit (Sfoc) of the solar cell through the junction recombination velocity. The determination of Sfoc obtained from the curve of photovoltage versus Sf, and the determination of Sfsc is through from the curve of the photocurrent density according to Sf.
