Spectral response of GaAs solar cell is analytically computed incorporating the existence of quasi-Fermi level generated after photon shower. Analytical computation is carried out for simultaneous solution of continuity equations and diffusion equations, and contribution of drift is also taken into account. Results are obtained by varying structural parameters within lower photon energy range to obtain higher response magnitude.
