Stabilizing α-phase FAPbI3 solar cells
文献摘要:
Organic-inorganic hybrid perovskite solar cells(PSCs)have been recognized as a promising and cost-effective photo-voltaic technology with the power conversion efficiency(PCE)exceeding 25%[1-3].The high efficiency is attributed to the exceptional optoelectronic properties,such as high absorp-tion coefficient,long carrier diffusion length,low non-radiat-ive recombination rate,and so on[4-7].Compared to methylam-monium lead triiodide(MAPbI3)perovskite,formamidinium lead triiodide(FAPbI3)perovskite exhibits better thermal and structural stability.Meanwhile,it has a narrower bandgap,which is close to the optimum bandgap for reaching Shockley-Queisser limit(Fig.1(a))[8].So,FAPbI3 is an ideal can-didate for highly efficient single-junction PSCs.However,the black photoactive α-FAPbI3 formed at high temperature(~150℃)can readily convert to photoinactive δ-FAPbI3 un-der ambient conditions[9-11],which is fatal to device perform-ance and stability.Therefore,various approaches have been proposed to overcome the phase transition.Here,we will dis-cuss three strategies:chloride-based additives,pseudo-hal-ide anion engineering and ionic liquid engineering.
