The regulated crystallization of perovskite and highly repeatable preparation are decisive challenges for large-scale flexible perovskite solar cells (PSCs).Herein,we synthesize an oil-soluble poly(3,4-ethylenedioxythiophene) (Oil-PEDOT) as a hole transport layer (HTL).The non-wetting Oil-PEDOT HTL can promote the quality of large-area flexible perovskite films because of its optimized crystallinity and printability.The Oil-PEDOT layer also delivers desirable conductivity and charge transport without a complex doping.Consequently,the flexible PSCs with Oil-PEDOT HTL achieve an efficiency of 19.51% and 16.70%based on 1.05 and 22.50 cm2,respectively.Moreover,these large-scale flexible PSCs demonstrate remarkable mechanical robustness,and the efficiency exhibits 93% retention after 7,000 bending cycles.These results show that the Oil-PEDOT is a potentially efficient HTL for fabricating efficient large-scale flexible PSCs.

The classical critical Trudinger-Moser inequality in R2 under the constraint ∫R2(| ▽u|2+|u|2)dx≤1 was established through the technique of blow-up analysis or the rearrangement-free argument:for any τ>0,it holds that sup u∈H1(R2)∫R2(τ|u|2+|Vu|2)dx≤1 ∫R2(e
Methane (CH4) is the main component of natural gas,causing severe greenhouse effect [1].To date,about 90% of CH4 is burned into carbon dioxide (CO2) and released into the atmosphere through various ways,resulting in not only a waste of resource but also a
The installation of azoles via C-H/N-H cross-coupling is significantly underdeveloped,particularly in benzylic C-H azolation due to the requirement for external chemical oxidants and the challenge in controlling the site-and chemo-selectivity.Herein,a lat
