摘要

Cs3Bi2I9 具有相对较高的带隙(2.03 eV)和超强的热稳定性,本文对基于三吸收层的新型过氧化物光伏电池进行了数值研究。将其与 CsSnGeI3 & CsSnI3 结合使用可提高所研究结构的功率转换效率。对 FTO/TiO2/(CsSnI3/CsSnGeI3/Cs3Bi2I9)/Cu2O/Au 电池配置进行的初步模拟得出的 PCE 为 27.59%,需要进行大量修改。为了优化器件结构,对各种参数进行了严格的测试,其中包括:(i) 调整三个吸收层中每个吸收层的厚度;(ii) 研究 4 种不同材料的适用性,即:TiO2、CdZnSi2、CdZnSi3/CsSnGeI3/Cs3Bi2I9/Cu2O/Au、(ii) 研究 4 种不同材料(即 TiO2、CdZnS、ZnO 和 SnS2)作为电子传递介质(ETM)的适用性;(iii) 研究 5 种化合物(如 Spiro-OMeTAD、Cu2O、NiO、MoOx 和 PEDOT:PSS)作为空穴传输介质(HTM)的适用性。最终优化的配置是 FTO/TiO2/(CsSnI3/CsSnGeI3/Cs3Bi2I9)/MoOx/Au,其中 0.8/0.1/0.1 μm 的 CsSnI3/CsSnGeI3/Cs3Bi2I9 被放置为三层,TiO2 作为 ETM 被放置在 0.1 μm,MoOx 作为 0.35 μm 的 HTM,被评估为最优化材料、JSC = 35.14 mA/cm2,VOC = 1.16 V,FF = 89.16%,PCE = 36.34%。该电池凸显了 CsSnI3/CsSnGeI3/Cs3Bi2I9 作为包晶三吸收层的巨大潜力,以及它对已评估的各种 ETM 和 HTM 的适用性,为制造高效电池指明了方向。

Simulation and optimization of a CsSnI3/CsSnGeI3/Cs3Bi2I9 based triple absorber layer perovskite solar cell using SCAPS-1D
This paper demonstrates a numerical study on a novel triple absorber layer-based perovskite photovoltaic cell incorporating Cs3Bi2I9, which offers a relatively high bandgap (2.03 eV) along with superlative thermal stability. Combining it with CsSnGeI3 & CsSnI3 led to enhanced power conversion efficiency in the studied structures. The preliminary simulation performed for the cell configuration, FTO/TiO2/(CsSnI3/CsSnGeI3/Cs3Bi2I9)/Cu2O/Au, resulted in a PCE of 27.59%, which needed extensive modification. To optimize the device structure, various parameters were rigorously tested, which included (i) tuning the individual thickness of each of the three absorber layers; (ii) studying the applicability of 4 different materials, i.e., TiO2, CdZnS, ZnO, and SnS2, for Electron Transfer Mediums (ETMs); and (iii) examining 5 compounds such as Spiro-OMeTAD, Cu2O, NiO, MoOx, and PEDOT:PSS;, for their usability as Hole Transfer Mediums (HTMs) as well. The finally optimized configuration FTO/TiO2/(CsSnI3/CsSnGeI3/Cs3Bi2I9)/MoOx/Au, where 0.8/0.1/0.1 μm of CsSnI3/CsSnGeI3/Cs3Bi2I9 is placed as a tri-layer, containing TiO2 as ETM of 0.1 μm and MoOx as HTM of 0.35 μm, which had been evaluated as the most-optimized material, exhibits notable photoelectric performance, i.e., JSC = 35.14 mA/cm2, VOC = 1.16 V, FF = 89.16%, and PCE = 36.34%. This cell underscores the remarkable potential of CsSnI3/CsSnGeI3/Cs3Bi2I9 as a perovskite tri-absorber layer along with its suitability for the various ETMs and HTMs that had been evaluated, directing in the path of manufacturing supremely efficient cells.

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.
