Abstract

In this article a frequency modulation study on a CIGS-based solar cells under the influence of incidence angle and gallium doping is made. The resolution of the minority carrier continuity equation allowed us to determine the density of minority carriers, the photocurrent density and photovoltage expressions according to modulation frequency, wavelength, incidence angle and gallium doping. Incidence angle and Gallium doping tend to decrease the performance of the solar cell by degrading its intrinsic properties.

Keywords:
CIGS frequency modulation wavelength incidence angle gallium doping photocurrent photovoltage
