中文摘要：

多金属氧酸盐（简称为多酸）作为一种分子型金属氧化物,具有结构的多样性和独特的物理化学性质,在催化、分子基功能材料、分子磁学等领域显示出广泛的应用。特别是近年来,利用多酸作为电子受体去捕获半导体材料中的光生电子,促进电荷分离并且抑制半导体中载流子的复合,从而有效地提高了半导体的光电转换效率,在半导体光电器件和太阳能电池中显示了应用潜力。本文基于我们的研究工作和近期文献,综述了多酸促进半导体光电转换作用的研究进展及其在太阳能电池中的应用,并且对其未来的发展方向进行了展望。

英文摘要：

Polyoxometalates（ POMs）,being one kind of molecular metal oxides,have structural variety and special physicochemical properties. They have showed broad applications in catalysis,molecule-based functional materials and molecular magnetism. In recent years,POMs can be used as electron acceptor to capture the photogenerated electrons from semiconductors. This facilitates charge separation and restrains electron-hole recombination. Thus the light-to-electricity conversion efficiency is obviously improved,which demonstrates the potential applications in both semiconductor devices and solar cells. In this review,based on our studies and recent literature,we summarize the advance of improving light-to-electricity conversion efficiency by POMs and their application in solar cells,and then make a prospect of future development in this area.
