Perovskite solar cells came to limelight owing to their simple fabrication processes, cost-effectiveness, better optoelectronic characteristics and outstanding power conversion efficiencies (PCEs). These solar cells have simply outpaced their rival cells since the alteration from aqueous hole transport layers (HTLs) to solid HTLs. Various layers of a perovskite cell viz. light absorber layer, electron transport layer (ETL) and HTL play a decisive role in ascertaining its performance. Today, various types of organic and inorganic HTLs are available but inorganic HTLs have gained an upper hand over their organic counterparts in terms of stability, cost, fabrication and material properties which represent them as a prospective candidate for optimum perovskite device. Copper antimony sulfide (CuSbS${}_2)$ is a common HTL available in abundance with the benefit of an adequate bandwidth of 1.54$$eV. In addition, CuSbS₂ possesses substantial band aligning and electron inhibiting features. This research paper elaborates a relative study of two perovskite solar devices possessing discrete inorganic hole transport layers, i.e., cuprous iodide (CuI) and copper antimony sulfide (CuSbS${}_2)$, and discrete perovskite layers, i.e., MAPbI${}_{3-x}$Cl${}_x$ and MASnI₃, using the same negative charge transport layer, i.e., Cd${}_{1-x}$Zn${}_x$S, through numerical simulation employing SCAPS-1D. The effects of thickness, defect density and doping concentration with respect to absorbing layer on the efficiency and other parameters of perovskite layers are also discussed. By employing CuSbS₂ with MASnI₃ in the proposed device, the solar cell parameters are efficacious enough demonstrating the $V_{\mathrm{\text{oc}}}$ of 1.10$$V, PCE of 31.11%, fill factor (FF) of 83.05% and $J_{\mathrm{\text{sc}}}$ of 33.75$$mA$$⋅$$cm${}^{-2}$.

钙钛矿太阳能电池因其简单的制造工艺、成本效益、更好的光电特性和出色的功率转换效率（PCE）而受到关注。自从从水性空穴传输层 (HTL) 转变为固体 HTL 以来，这些太阳能电池的速度已经远远超过了竞争对手的电池。钙钛矿电池的各个层即。光吸收层、电子传输层（ETL）和HTL对其性能起着决定性作用。如今，有各种类型的有机和无机 HTL 可用，但无机 HTL 在稳定性、成本、制造和材料性能方面比有机 HTL 更具优势，这表明它们是最佳钙钛矿器件的潜在候选者。硫化铜锑 (CuSbS${}_2）$是一种常见的 HTL，资源丰富，具有 1.54 足够的带宽$$eV。此外，CuSbS ₂具有显着的能带排列和电子抑制特征。该研究论文阐述了两种具有离散无机空穴传输层的钙钛矿太阳能器件的相关研究，即碘化亚铜（CuI）和硫化铜锑（CuSbS）${}_2）$和离散钙钛矿层，即 MAPbI${}_{3-X}$氯${}_X$和MASnI ₃，使用相同的负电荷传输层，即Cd${}_{1-X}$锌${}_X$S，通过采用SCAPS-1D的数值模拟。还讨论了吸收层的厚度、缺陷密度和掺杂浓度对钙钛矿层的效率和其他参数的影响。通过在所提出的装置中使用 CuSbS ₂和 MASnI ₃，太阳能电池参数足够有效，证明了$V_{\mathrm{\text{奥克}}}$共 1.10$$V，PCE 为 31.11%，填充因子 (FF) 为 83.05%，$J_{\mathrm{\text{SC}}}$共 33.75$$嘛$$⋅$$厘米${}^{-2}$。
