Initially, TiO 2 layer of varying thickness was used as anti-reflector and absorber without InP nanorods to determine the optimal thickness to maximize carrier generation, while keeping the Si layer thickness fixed. The bottom Ag layer acts as a back reflector and a metallic contact. The results revealed the use of a 200 nm thick TiO 2 layer maximized career generation and short-circuit current. 3.2 eV bandgap of the TiO 2 layer enhances UV light absorption and serves as a protective layer for the Si layer (which has weak performance in the UV band due to surface recombination). Next, the InP nanorods were formed at the interface of TiO 2 and Si layers. These nanorods were optimized for key operations, such as light scattering, recombination, surface area enhancement, and quantum effects. Herein, the Mie resonance was studied in larger InP nanorods and the impact of weak Mie resonance on the quantum effect due to the smaller ones. The solar cell model includes a silver base and silver emitter to extract the I-V characteristics. The maximum efficiency of ∼6.51% was achieved using the InP nanorods of 5 nm radius and 20 nm thickness – the case which significantly enhances the quantum confinement effect and improves the bandgap, allowing for extended light harvesting in the UV and visible regime. solar cell InP nanorods localized Mie resonance carrier generation rate photocurrent Full Text Additional Declarations No competing interests reported.
