| titleOfInvention | Catechol-anchored molecule passivation perovskite solar cell containing long fluorocarbon chain and preparation method thereof |
| abstract | The invention discloses a catechol anchor molecule passivation perovskite solar cell containing a long fluorocarbon chain and a preparation method thereof. An amidation reaction is used to synthesize an anchor molecule containing a catechol passivation group and a long fluorocarbon chain ; Spin-coat perovskite precursors on conductive glass substrates to form mesophase films, introduce the anti-solvent solution of anchor molecules into the mesophase films to form perovskite films modified by anchor molecules, prepare hole transport layers, evaporate Metal electrodes are plated to obtain perovskite solar cells. The invention synthesizes anchor molecules through one-step amidation reaction, introduces anchor molecules containing functional groups and long carbon fluorine chains on the grain boundary and surface of the perovskite layer, passivates the defects of the perovskite body phase, and reduces the photogenerated load The non-radiative recombination of the electrons and their extraction and transport at the interface enhance the device's resistance to water and oxygen. Compared with unmodified perovskite solar cells, the power conversion efficiency is increased and the humidity stability is greatly improved. |
