Thin‐film solar cells based on hydrogenated amorphous silicon (a‐Si:H) and conjugated polymers have been studied extensively. However, organic–inorganic hybrid tandem incorporating the two materials as subcells are yet to be extensively studied. Here, a computational study optimal design of achieve maximum possible efficiency is presented. The optical simulations predict an cell, desirable for wide range spectral response high efficiency. optimum combination thicknesses a‐Si:H organic photovoltaic (OPV) highest in terms short circuit current ( J sc ) determined. Thicknesses 400 140 nm OPV subcells, respectively, suggested optimised cell matching power conversion 11.57%.
