- W3210271447 abstract "In this work, we design a novel cadmium telluride (CdTe)-based solar structure with antimony sulfide (Sb2S3) as hole transport layer (HTL). One Dimensional Solar Cell Capacitance Simulator (SCAPS-1D) program is used to perform comparison studies on the photovoltaic performances between the standard thin-film cadmium sulfide (CdS)/CdTe solar cell and the proposed Al/FTO/CdS/CdTe/Sb2S3/Ni heterojunction structure. The solar cell outputs such as open-circuit voltage (Voc), short-circuit current density (Jsc), fill-factor (FF), and efficiency have been evaluated by varying impacts of thickness, electron affinity, carrier concentration, and bulk defect density of different layers. In addition, we have analyzed the effect of interface defects at both CdS/CdTe and CdTe/Sb2S3 interfaces. This study reveals that the introduction of Sb2S3 as HTL improves the Voc appreciably by creating appropriate band alignment with the CdTe absorber and thus remarkably enhance the efficiency of solar cell by lowering carrier recombination at back contact surface. Moreover, the impacts of working temperature, back contact metal work function, and surface recombination velocity are elucidated. The absorber thickness is optimized to be 1.0 µm with doping concentration of 2.1 × 1015 cm−3. Best efficiency of 28.41% together with other parameters such as Voc of 1.15 V, Jsc of 28.74 mA/cm2, and FF of 86.03% is achieved for the optimized device. These results lead to suggest that the Sb2S3 as HTL can be employed to fabricate highly efficient and inexpensive thin-film CdTe heterojunction solar devices." @default.
