Overcoming Perovskite Corrosion and De-Doping Through Chemical Binding of Halogen Bonds Toward Efficient and Stable Perovskite Solar Cells
文献摘要：
4-tert-butylpyridine(TBP)is an indispensable additive for the hole transport layer in highly efficient perovskite solar cells(PSCs),while it can induce corrosion decomposition of perovskites and de-doping effect of spiro-OMeTAD,which present huge challenge for the stability of PSCs.Herein,halogen bonds provided by 1,4-dii-odotetrafluorobenzene(1,4-DITFB)are employed to bond with TBP,simultaneously preventing perovskite decomposition and eliminating de-doping effect of oxidized spiro-OMeTAD.Various characterizations have proved strong chemical interaction forms between 1,4-DITFB and TBP.With the incorporation of halogen bonds,perovskite film can maintain initial morphology,crystal structure,and light absorb-ance;meanwhile,the spiro-OMeTAD film shows a relatively stable conductivity with good charge transport property.Accordingly,the device with TBP complex exhibits significantly enhanced stability in N2 atmosphere or humidity environment.Furthermore,a champion power conversion efficiency of 23.03％is obtained since perovskite is no longer damaged by TBP during device preparation.This strategy overcomes the shortcomings of TBP in n-i-p PSCs community and enhances the application potential of spiro-OMeTAD in fabricating efficient and stable PSCs.
