Hyperbranched phthalocyanine enabling black-phase formamidinium perovskite solar cells processing and operating in humidity open air
文献摘要:
The extreme instability of pure α-phase FAPbI3 under high humidity conditions restricts the high-throughput fabrication in unmodified air environments,resulting in poor performance of α-phase FAPbl3 perovskite devices obtained by scalable fabrication methods.Here we synthesized hyperbranched copper phthalocyanine(HCuPc)as a supramolecular additive with twisted phthalocyanine units to real-ize the molecular-level encapsulation at the grain boundaries through supramolecular interaction,which greatly broadened the processing window of FAPbI3 under high humidity.At the same time,unlike tra-ditional encapsulation layer that carrier can only be collected by tunneling effect,the twisted phthalocya-nine ring of HCuPc in perovskite films is more conducive to hole extraction.Finally,a record efficiency was achieved in pure FAPbI3 based inverted structured solar cell by blade-coating to the best of our knowledge,even under unmodified humid air conditions(relative humidity of 65%-85%).The best oper-ational stability of 3D pure FAPbl3 devices can also be achieved at the same time and unencapsulated HCuPc-FAPbI3 device can even operate with negligible degradation for 100 h in the open air(RH 30%-40%).
