Abstract

Perovskites are highly promising materials for photovoltaic (PV) technology due to their superior optical properties, cost-effectiveness, high efficiency, and lightweight nature. This study proposes a novel dual-absorber PV device featuring strontium arsenic iodide (Sr₃AsI₃) as the top layer and strontium phosphorus iodide (Sr₃PI₃) as the bottom layer, analyzed using SCAPS-1D simulations. The research investigates the influence of absorber thickness, doping concentrations, and defect densities on electrical parameters such as V_OC, J_SC, FF, and PCE, alongside the effects of temperature and resistance (shunt and series). Initial simulations of two single-junction PSCs yielded PCEs of 29.93 % for FTO/CdS/Sr₃PI₃/Au and 30.09 % for FTO/CdS/Sr₃AsI₃/Au. Upon optimization, the dual-absorber PSC (Al/FTO/CdS/Sr₃AsI₃/Sr₃PI₃/Au) achieved a maximum PCE of 32.20 %, with a V_OC of 1.02 V, J_SC of 36.50 mA/cm², and an FF of 86.80 %. This study provides valuable insights and practical strategies for the development of cost-effective, thin-film PSCs based on Sr₃AsI₃/Sr₃PI₃.

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
