摘要

摘要本研究利用SCAPS-1D工具对含CdS电子传输层(ETL)和cu2o空穴传输层(HTL)的过渡金属二硫族化合物(TMDC)基钼二碲化钼(MoTe 2)太阳能电池的性能进行了数值研究。基于光伏电池参数，包括吸收层厚度、温度、缺陷密度、串联和并联电阻的影响以及电子亲和力，分析了使用HTL和不使用HTL时MoTe 2基太阳能电池的结构。在MoTe 2厚度为1.1 μm，掺杂密度为5 × 10 15 cm−3的情况下，优化了Al/FTO/CdS/MoTe 2 / cu2o /Ni异质结太阳能电池结构。优化后的结构得到最终功率转换效率(PCE)为32.38%，开路电压(voc)为1.07 V，短路电流(jsc)为35.12 mA/ cm2，填充系数(FF)为86.32%。确定的结果为实现低成本、高效率的MoTe 2基太阳能电池指明了一条合适的途径。

Assessing the performance of MoTe2 based solar cell with Cu2O hole transport layer through device simulation

Abstract In this study, the SCAPS-1D tool has been used to numerically examine the performance of Transition Metal Dichalcogenides (TMDC) based Molybdenum ditelluride (MoTe 2 ) solar cells containing CdS electron transport layer (ETL) and Cu 2 O hole transport layer (HTL). Based on the photovoltaic cell parameters, including absorber layer thickness, temperature, defect density, the effects of series and shunt resistance, and electron affinity, the structure of both MoTe 2 based solar cells with and without the usage of the HTL has been analyzed. With 1.1 μm thickness of MoTe 2 and doping density of 5 × 10 15 cm −3 , Al/FTO/CdS/MoTe 2 /Cu 2 O/Ni heterojunction’s solar cell proposed structure has been optimized. The final power conversion efficiency (PCE) = 32.38%, open-circuit voltage (V oc ) = 1.07 V, short-circuit current (J sc ) = 35.12 mA/cm 2 , and fill factor (FF) = 86.32% has been determined from the optimized structure. The determined results indicate a suitable path for the realization of low cost and high efficiency MoTe 2 -based solar cell.

期刊介绍： Discover Materials is part of the Discover journal series committed to providing a streamlined submission process, rapid review and publication, and a high level of author service at every stage. It is a broad, open access journal publishing research from across all fields of materials research. Discover Materials covers all areas where materials are activators for innovation and disruption, providing cutting-edge research findings to researchers, academicians, students, and engineers. It considers the whole value chain, ranging from fundamental and applied research to the synthesis, characterisation, modelling and application of materials. Moreover, we especially welcome papers connected to so-called ‘green materials’, which offer unique properties including natural abundance, low toxicity, economically affordable and versatility in terms of physical and chemical properties. They are the activators of an eco-sustainable economy serving all innovation sectors. Indeed, they can be applied in numerous scientific and technological applications including energy, electronics, building, construction and infrastructure, materials science and engineering applications and pollution management and technology. For instance, biomass-based materials can be developed as a source for biodiesel and bioethanol production, and transformed into advanced functionalized materials for applications such as the transformation of chitin into chitosan which can be further used for biomedicine, biomaterials and tissue engineering applications. Green materials for electronics are also a key vector concerning the integration of novel devices on conformable, flexible substrates with free-of-form surfaces for innovative product development. We also welcome new developments grounded on Artificial Intelligence to model, design and simulate materials and to gain new insights into materials by discovering new patterns and relations in the data.
