摘要

and RGO is synthesized by hydro-thermal method. Besides, the photoelectrode of DSSC is fabricated by a simple process of spin coating. According to experimental results, the photovoltaic conversion efficiency increases slowly during decreases in illumination, but which falls sharply at the lowest illumination. Furthermore, the photovoltaic conversion efficiency is enhanced from 4.01% to 4.91% under low illumination. According to experimental results, the reason of increase in photovoltaic conversion efficiency of DSSC under low illumination is due to the improvement of electron injection quantum yield. Moreover, the reason of increase in photovoltaic conversion efficiency is clarified.
