Abstract

Halide perovskites are the most promising options for extremely efficient solar absorbers in the field of photovoltaic (PV) technology because of their remarkable optical qualities, increased efficiency, lightweight design, and affordability. This work examines the analysis of a dual-absorber solar device that uses SrSbI as the bottom absorber layer and SrPI as the top absorber layer of an inorganic perovskite through the SCAPS-1D platform. The device architecture includes ZnSe as the electron transport layer (ETL), while the active layer consists of SrPI and SrSbI with precise bandgap values. The bandgap value of SrSbI is 1.307 eV and SrPI is 1.258 eV. By employing double-graded materials of SrPI/SrSbI, the study achieves an optimized efficiency of up to 34.13% with a of 1.09 V, FF of 87.29%, and of 35.61 mA cm. The simulation explores the influence of absorber layer thickness, doping level, and defect density on electrical properties like efficiency, short-circuit current, open-circuit voltage, and fill factor. It also examines variations in temperature and assesses series and shunt resistances in addition to electrical factors. The simulation's output offers valuable insights and suggestions for designing and developing double-absorber solar cells.

摘要

卤化物钙钛矿因其卓越的光学品质、更高的效率、轻量化设计和可承受性，成为光伏（PV）技术领域极高效太阳能吸收体最具潜力的选择。这项工作通过SCAPS - 1D平台研究了一种双吸收体太阳能器件，该器件使用SrSbI作为无机钙钛矿的底部吸收层，SrPI作为顶部吸收层。器件结构包括ZnSe作为电子传输层（ETL），而有源层由具有精确带隙值的SrPI和SrSbI组成。SrSbI的带隙值为1.307 eV，SrPI的带隙值为1.258 eV。通过采用SrPI/SrSbI的双梯度材料，该研究实现了高达34.13%的优化效率，开路电压为1.09 V，填充因子为87.29%，短路电流密度为35.61 mA/cm²。该模拟探究了吸收层厚度、掺杂水平和缺陷密度对诸如效率、短路电流、开路电压和填充因子等电学性能的影响。它还研究了温度变化，并除电学因素外评估了串联电阻和并联电阻。模拟结果为双吸收体太阳能电池的设计和开发提供了有价值的见解和建议。
