Abstract

We report a promising photoanode material of FeO/BiOI for efficient photoelectric conversion in solar cells, which was fabricated with BiOI attached to a one-dimensional FeO nanorod array. The two semiconductors of p-type BiOI and n-type FeO formed a heterogeneous structure for efficient charge separation. The highest open circuit voltage and short circuit current of the solar cell can reach 0.41 V and 4.89 mA/cm, respectively. This study opens an available field to develop low-cost and environmentally friendly photoelectric materials for solar cells.

摘要

我们报告了一种有前途的光电阳极材料 FeO/BiOI，用于太阳能电池中的高效光电转换，该材料是通过将 BiOI 附着在一维 FeO 纳米棒阵列上制备的。p 型 BiOI 和 n 型 FeO 两种半导体形成了一种异质结构，可实现有效的电荷分离。太阳能电池的最高开路电压和短路电流分别可达 0.41 V 和 4.89 mA/cm。这项研究为开发用于太阳能电池的低成本、环保光电材料开辟了一个可行的领域。
