Abstract :
We reported on optoelectronic properties of the Cu(InGa)Se2 (CIGS) solar cell fabricated by sputtering method on stainless steel substrate having external efficiency of ~13.0%. Experimental data indicates that the quantum efficiency (QE) has a high response for long wavelength light. Current density (J) - voltage (V) measurements under illumination resulted in short circuit current density of 32.08 mA/cm2 and open circuit voltage of 0.55 V. We have also performed modeling of this device establishing that both experimental and calculated data are consistent with each other.
