Abstract

The photovoltaic effect in pure cadmium-alkanoate matrices and in their nanocomposites with semiconductor CdS nanoparticles (NPs) was revealed and investigated. The main mechanism of the phenomenon is the Dember effect, in which the internal field of non-equilibrium charge carriers is formed due to a significant difference in the mobility of positive and negative charges. NPs synthesized in the matrix lead to a significant increase in the concentration of the photo-generated electrons and thus to an increase in the photo-electro-driving force in the material. The magnitude and kinetics of the photocurrent for nanocomposites substantially depend on the content of only a small amount (2 − 4 mol. %) of NPs.

含半导体纳米粒子的镉基离子液晶的光伏特性

摘要

揭示并研究了纯链烷酸镉基体及其与半导体 CdS 纳米粒子 (NPs) 的纳米复合材料中的光伏效应。该现象的主要机制是登伯效应,其中由于正电荷和负电荷的迁移率存在显着差异而形成非平衡电荷载流子的内部场。在基质中合成的 NP 导致光生电子浓度显着增加,从而导致材料中的光电驱动力增加。纳米复合材料的光电流大小和动力学在很大程度上取决于仅少量 (2-4 mol.%) NP 的含量。
