Abstract |
Organometal halide perovskite solar cells (PSCs) have achieved astounding progress in the past few years and a very high recorded power conversion efficiency (PCE) of 22%. Notable achievements of primary device configuration involving perovskite layer, hole-transporting materials (HTMs) and electron-transporting materials (ETMs) are reviewed. However, there does not fully understand the effect of HTMs, here such a lithium bis(trifluoromethylsulfonyl)-imide doped 2,2’,7,7’-tetrakis(N,N-di-p-methoxyphenylamine)-9,9’-spirobifluorene (Spiro-OMeTAD), on PSCs. On the one hand, the loss of performance of PSCs is commonly attributed to degradation of the perovskite itself. On the other hand, it is needed time for LiTFSI-doped Spiro-OMeTAD hole-transporting layer reaching its conductivity stable after fabrication and storage. In this paper, we study the contribution of the conductivity of LiTFSI-doped Spiro-OMeTAD to the overall current-voltage behavior of PSCs. The mechanism of light and air-exposure are also discussed to overcome the critical issues for a suitable progress of PSCs and related opto-electronic deivces. |
