Abstract

Recently, solar cells have appeared as a promising solution to meet the increasing energy demand. However, their large-scale commercial use is limited by issues such as toxicity (Cd, Pb, etc), high manufacturing costs, lower stability, and low efficiency. In this perspective, kusachiite solar cells (KSCs) are environmentally friendly, long-term stable, and easy to manufacture. Thus, in this work, kusachiite (CuBi₂O₄) is used as an absorber layer, with NiO and SrTiO₃ serving as the hole transport material (HTM) and an electron transport layer (ETL), respectively. The KSCs, with a structure of FTO/SrTiO₃/CuBi₂O₄/NiO/Au, are numerically simulated. Maximum power conversion efficiency is achieved by optimizing several photovoltaic parameters, such as the thickness and doping density of the ETL, absorber, and HTM. The optimized thicknesses for the HTL, absorber layer, and ETL are 1.5 μm, 2.28 μm, and 0.02 μm, respectively. The designed KSCs exhibit an efficiency eta (η) of 31.89 %, an open-circuit voltage (V_oc) of 1.31 V, a short-circuit current (J_sc) of 28.58 mA/cm², and a fill factor (FF) of 84.99 %.

探索环保型草晶岩太阳能电池 32% 的效率：数值研究

最近，太阳能电池已成为满足日益增长的能源需求的一种有前途的解决方案。然而，由于其毒性（镉、铅等）、高制造成本、低稳定性和低效率等问题，其大规模商业应用受到了限制。从这个角度来看，草晶石太阳能电池（KSCs）具有环保、长期稳定、易于制造等优点。因此，在这项研究中，Kusachiite（CuBi2O4）被用作吸收层，NiO 和 SrTiO3 分别用作空穴传输材料（HTM）和电子传输层（ETL）。对结构为 FTO/SrTiO3/CuBi2O4/NiO/Au 的 KSC 进行了数值模拟。通过优化几个光伏参数，如 ETL、吸收器和 HTM 的厚度和掺杂密度，实现了最大功率转换效率。HTL 、吸收层和 ETL 的优化厚度分别为 1.5 μm、2.28 μm 和 0.02 μm。所设计的 KSC 的效率 eta (η) 为 31.89%，开路电压 (Voc) 为 1.31 V，短路电流 (Jsc) 为 28.58 mA/cm2，填充因子 (FF) 为 84.99%。

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.
