摘要：

This paper presents a systematic investigation on the effects of iodine content in the electrolyte on electron recombination, charge, and ion transportation to the power conversion performance of dye-sensitized solar cells under lower light intensities. By analyzing the current-voltage behavior and electrochemical impedance spectroscopy results, the effects of iodine content on charge recombination, ion transportation, and light intensity are found to be the major factors. The power conversion efficiency of DSSC under low light intensity can be significantly improved when electrolyte composition is optimized, which results in an exclusive application for indoor use.
