The effects of ZnP on the corresponding PSCs were then examined.Here we selected a commonly used mesoporous PSCs configuration with FTO/compact Ti O2/mesoporous Ti O2/perovskite/Co（II）-and Co（III）-based porphyrins[38]（Figure S7）/Au configuration（Figure S8）.Their performances were evaluated under the illumination of AM 1.5，100 mW cm-2.As shown in Figure 4 and Table S1（Supporting Information online），the increased performance was observed with the enhancement of ZnP amount from 0 to0.05%.The best performance of PSC with 0.05%ZnP was up to 20.0%with the small-area（0.10 cm2），much higher than that of the PSC with pure MAPbI3，18.8%.The Jscof the champion PSCs was further assessed by the almost consistent values from the incident photon-to-current conversion efficiency（IPCE）data（Figure S9）.Due to the accomplishment of efficient ions immobilization with ZnP introduction，the reduced hysteresis was also found for the ZnP-based PSC（Figure 4(a）and Table S1).To further evaluate the champion efficiency，the stabilized efficiency output of 19.6%by monitoring at the maximum power point for over 200 s（Figure S10）was performed.Measurements over 30 devices further offered an average efficiency of 19.1%±1.0%for PSCs with ZnP doping，while the control device was 17.7%±1.1%（Figure 4(b）).Due to the occurrence of poor quality of the perovskite with 0.1%ZnP doping（Figure S2），the corresponding device revealed reduced cell performance（Figure S11 and Table S2）.Finally，the best efficiency of 0.05%ZnP-based PSC with an area of 1.96 cm2reached 19.0%（Figure 4(c）)，outperforming the value（18.3%）of the PSC with monoammonium zinc porphyrin reported in our previous work[32].To further demonstrate the effects of ZnP in PSCs devices，we also prepared perovskite films by spincoating technique.As illustrated in Figure S12 and Table S3，the significantly improved perovskite film quality and photovoltaic performance clearly claimed the introduction of ZnP can efficiently achieve ions immobilization in perovskite films，and offering a novel doping approach to fabricate efficient large-area PSCs devices.
