Herein, we investigate the suitability of a CdS film as the p+/IB/n+ layers within the IBSC structure using numerical solutions. Initial benchmarking with the theoretically reported device in the literature is performed by incorporating optimal, non-overlapping sub-bandgap absorption using a custom ASCII file. It is observed that the simulated device can effectively harness energy from low-energy red light to high-energy violet light by employing three optical transitions. The results confirm that a thickness of 1 µm and a donor concentration of 10 14 cm -3 are optimal for the absorber to reach the upper limit efficiency of 46%, with both the p+ and n+ layers being 0.1 µm thick with an acceptor/donor density of 10 18 cm -3 , respectively. The field near the junction is shown to amplify, and the depletion width is widest at 0.97 µm, approximating the thickness of the absorber at this donor level. Additionally, inadequate impurity-host atom substitution could lead to the formation of discrete levels, which are detrimental at high defect concentrations. A defect concentration of 10 18 cm -3 counteracts the contribution from generation, thus detrimentally depreciating the overall efficiency.
