摘要
本研究评估了掺杂锰对通过喷雾热解沉积在对硅衬底上的氧化锌薄膜的光伏特性的影响。锰的浓度分别为 0、1 和 3 wt%。喷雾在 400 °C 下进行,持续 10 分钟。结果表明,X 射线衍射图样显示,随着锰掺杂量的增加,晶体尺寸线性减小,从 44 纳米(0% Mn)减小到 31 纳米(3% Mn)。扫描电子显微镜图像显示,锰浓度的增加导致纳米结构尺寸变小,从 325 纳米(0% Mn)减小到 112.3 纳米(3% Mn)。有趣的是,在偏置电压为 0 V 而不是 1 V 和 5 V 时,掺杂 3% Mn 的样品具有最佳的光敏性和响应时间,这表明其具有光生伏打效应。这一结果对于开发未来的自供电器件非常重要。
Enhancement in ZnO-based self-powered photodetector by inserting Mn dopant
In this study, the effect of Mn doping on the photovoltaic properties of ZnO films deposited on a p-Si substrate via spray pyrolysis has been evaluated. The Mn concentration was varied at 0, 1, and 3 wt%. The spray was carried out at 400 °C for 10 min. As a result, the X-ray diffraction pattern shows that the crystallite size decreases linearly with increasing Mn doping, from 44 nm (0% Mn) to 31 nm (3% Mn). Scanning electron microscopy images show that the increase in Mn concentration causes the nanostructure size to be smaller, from 325 nm (0% Mn) to 112.3 nm (3% Mn). Interestingly, the best photosensitivity and response time are found in the doped sample (3% Mn) at a bias voltage of 0 V rather than 1 V and 5 V, indicating the photovoltaic effect. This result is important to develop future self-powered devices.
