Abstract
This study focuses on enhancing the performance of photodetector through the utilization of inorganic perovskite material. It emphasizes that the unique properties of perovskite materials contribute to the superior performance of the photodetector. The focus is on the design and enhancement of CsSnI3-based photodetector having graphene oxide (GO) and PCBM as charge transport layer, analysing their potential for improved operation. The design process involves a series of optimizations to the device layers, particularly the absorber layer's thickness and defects, which is critical for enhanced efficiency. The designed photodetector exhibits a better responsivity and detectivity in red and near infrared region and maximum responsivity of 0.68 A/W and detectivity of 9 × 1012 Jones. The SCAPS-1D tool is employed to facilitate the design analysis, enabling the fine-tuning of the device parameters. The findings highlight the effectiveness of perovskite materials in boosting photodetector performance.
本研究的重点是利用无机钙钛矿材料来提高光电探测器的性能。强调了钙钛矿材料的独特性质有助于光电探测器的优越性能。重点是设计和增强以氧化石墨烯（GO）和PCBM为电荷传输层的基于cssni3的光电探测器，分析其改进操作的潜力。设计过程涉及对器件层的一系列优化，特别是吸收层的厚度和缺陷，这对提高效率至关重要。所设计的光电探测器在红光和近红外区域具有较好的响应率和探测率，最大响应率为0.68 a /W，探测率为9 × 1012琼斯。采用SCAPS-1D工具进行设计分析，实现器件参数的微调。这一发现突出了钙钛矿材料在提高光电探测器性能方面的有效性。
