Polymer passivation of defects in inorganic perovskite solar cells
文献摘要：
Inorganic perovskite solar cells(IPSCs)have attained attention due to their excellent thermal and phase stability.In this work,we demonstrate a novel approach for fabricating IPSCs,using the strategies of interface passivation and anti-solvent before spin-coating perovskite.Poly(methyl methacrylate)(PMMA)and chlorobenzene(CB)are used as passivator and anti-solvent,respectively.The CB improves the perovskite crystal morphology.Meanwhile,PMMA passivates the defects between poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)(PEDOT∶PSS)and perovskite layer,thus increasing the short-circuit current.Excitingly,we find that PMMA benefits the grain boundaries(GBs)of perovskite,which makes it more humidity-resistant,increasing the stability of perovskite film.Especially,PMMA mitigates interfacial charge losses,and the devices based on CsPbI3-xBrx passivated by PMMA ex-hibit the power conversion efficiency(PCE)much higher than those based on pure CsPbI3.xBrx.
