Light-induced chemically resolved electrical measurements (CREM) under controlled electrical conditions are used to study photovoltaic effects at selected regions in nanocrystalline CdSe-based films. The method, based on X-ray photoelectron spectroscopy (XPS), possesses unique capabilities for exploring charge trapping and charge transport mechanisms, combining spectrally filtered input signals with photocurrent detection and with a powerful, site-selective, photovoltage probe.
在可控电学条件下进行的光诱导化学分辨电学测量(CREM)被用于研究基于纳米晶CdSe薄膜中选定区域的光伏效应。该方法基于X射线光电子能谱(XPS),结合了光谱滤波输入信号、光电流检测以及强大的、位点选择性的光电压探针,在探索电荷俘获和电荷传输机制方面具有独特的能力。
