titleOfInvention | A kind of fullerene derivative and its preparation method and perovskite solar cell |
abstract | The invention relates to the technical field of the technical field of perovskite solar cell materials, and provides a fullerene derivative, a preparation method thereof, and a perovskite solar cell. The porphyrin ring and ester group in the chemical structure of fullerene derivatives can chelate with lead ions in perovskite solar cells to fix the lead ions with saturation at the grain boundaries of perovskite thin films, thereby reducing lead leakage in the battery The fullerene group contained in its structure has excellent electron transport ability, and its functional group can effectively passivate the defects in the perovskite film through chemical interaction, thereby improving the photoelectric conversion efficiency of the device. Therefore, the fullerene derivative provided by the present invention not only has the ability to solidify lead ions in the perovskite battery, thereby reducing the risk of lead leakage in the battery; and the perovskite solar cell prepared by using the fullerene derivative provided by the present invention also has Has better photoelectric conversion efficiency. |
