A universal ionic liquid solvent for non-halide lead sources in perovskite solar cells
文献摘要:
Replacing lead iodide(Pbl2)with suitable non-halides lead source has been found to be an effective method to control crystallization and fabricate high-performance perovskite solar cells(PSCs).However,the solubility of non-halide lead sources is highly limited by traditional solvents due to the chemical interaction limitation.Here,we report a series of non-halide lead sources(e.g.,lead acetate(PbAc2),lead sulfate(PbSO4),lead carbonate(PbCO3),lead nitrate(Pb(NO3)2),lead formate(Pb(HCOO)2)and lead oxalate(PbC2O4))can be well dissolved in an ionic liquid solvent methylammonium acetate(MAAc).We found that the universal strong coordination of C=O with lead ion(Pb2+)and the for-mation of hydrogen bonds were observed in perovskite precursor solution.This allows the dissolution of non-halide lead salts and is able to produce perovskite film with smooth,compact,and full coverage crys-tal grain.The power conversion efficiency(PCE)of 14.48%,19.21%,and 20.13%in PSCs based on PbSO4,PbAc2,and PbCO3 was achieved,respectively,in the absence of any additives and passivation agents.This study demonstrates the universality of ionic liquid for the preparation of PSCs based on non-halides lead sources.
