Stabilizing black-phase CsPbl3 under over 70％humidity
文献摘要：
Recently,all-inorganic perovskites have attracted atten-tion due to good thermal stability[1-12].Among them,CsPbl3 has the most desirable optical bandgap(～1.7 eV)for applica-tions in optoelectronic devices[13-16].In general,making black-phase CsPbl3 film requires a high-temperature anneal-ing up to 320℃[17,18],which inevitably raises energy consump-tion.Though being made at high temperature,the resulting black-phase(α or β phase)CsPbl3 film still suffers from an un-desirable phase transition under ambient conditions[19,20].Sev-eral strategies have been developed to lower the annealing temperature(90-100℃)[20-26],it is still challenging to stabil-ize black-phase CsPbl3 under ambient condition with high hu-midity and without a tedious annealing process.Herein,we de-veloped a simple crystal redissolution(CR)strategy to make stable black-phase CsPbl3 film in ambient air with high humid-ity and without post-annealing.4-N,N-dimethylamino-4'-N'-methyl-stilbazolium tosylate(DAST)can chemically interact with CsPbl3 to reduce the formation energy of black-phase and inhibit CsPbl3 to undergo black-to-yellow phase trans-ition.
