摘    要:As a new type of renewable energy, solar energy offers a promising future in application. In 1991, Gratzel1] de-veloped a new type of solar cell, dye-sensitized nanopor-ous TiO2 solar cell (DSSC) which took the complex of ruthenium as the sensitizer. This solar cell has brought up the world’s attention with a high conversion efficiency of about 7.1%―7.9% and the high current intensity above 12 mA/cm2. Nowadays, with the overall conversion effi-ciency improved up to 11.18% 2―4], DSSC …

Abstract:DSSC has been a subject of intense study throughout the world. The efforts to investigate DSSC are mainly focused on how to increase light absorption, speed electron transport in circuit and reduce charge recombination. In this article, the development of charge recombination in DSSC is discussed, and the investigating techniques, main paths, mechanism and main inhibiting methods of charge recombination in DSSC are also described.
Keywords:recombination  time-domain technique  frequencydomain technique  electron transfer  surface state
