Abstract
Strontium antimony iodide (Sr3SbI3) showing distinct structural, electrical, and optical features is a recently developing potential absorber material for designing efficient and affordable solar cells. In this study, the physical properties such as structural, optical, and electronic properties including the photovoltaic (PV) performance of Sr3SbI3 absorber-based double-heterojunction solar cells have been studied and analyzed systematically. At first, the optoelectronic properties of the Sr3SbI3 absorber layer were investigated using first-principles density functional theory in detail. In the beginning, the impact of several probable metals as rear and front contacts was considered to identify the metal–semiconductor interface’s least resistive junction, where aluminum (Al) was mentioned as the best possible front contact and nickel (Ni) as the back contact. Then, the PV performance of novel Sr3SbI3 absorber-based cell structures for the different hole transport layers (HTLs) of MoO3, Cu2O, P3HT, CuO, and CFTS, with SnS2 as the transition-metal dichalcogenide electron transport layer (ETL), was studied at different layer thicknesses, doping density, total and interface defect densities, working temperature including the rate of carrier generation and recombination by determining the quantum efficiency, and the current density–voltage (J–V) via SCAPS-1D simulator software. Finally, optimization of all HTLs with the absorber, the highest power conversion efficiency (PCE) of 33.25% with JSC of 34.72 mA/cm2, FF of 85.92%, and VOC of 1.11 V, was obtained for MoO3 HTL, while the minimum PCE of 17.12%, with JSC of 29.57 mA/cm2, FF of 80.61%, and VOC of 0.72 V, was obtained for CFTS HTL, respectively. These results unveil the strong potentiality of the Sr3SbI3 absorber, with SnS2 as ETL and MoO3 as HTL for experimental fabrication of the high-performance perovskite heterostructure solar cell in the near future.
