Description

technical field [0001] The invention relates to the technical field of photovoltaic utilization of solar energy, and more specifically relates to a solar cell with high conversion efficiency and a preparation method thereof. Background technique [0002] The photoelectric conversion efficiency of solar cells has always been the focus of researchers. For dye-sensitized nano solar cells, the conversion efficiency of the new device can reach more than 11%, but the researchers believe that there is still room for improvement. The main factor affecting the conversion efficiency of dye-sensitized nano-solar cells is the generation of dark current during device operation, so suppressing dark current will be an effective way to improve the conversion efficiency of dye-sensitized nano-solar cells. [0003] In the generation of photocurrent, the dye will transition from the ground state to the excited state upon photoexcitation and release electrons. Since the lowest unoccupied mole...
