Abstract: Organolead trihalide perovskite materials have been successfully used as light absorbers in efficient photovoltaic cells. Two different cell structures, based on mesoscopic metal oxides and planar heterojunctions have already demonstrated very impressive advances in performance. Here, we report a bilayer architecture comprising the key features of mesoscopic and planar structures obtained by a fully solution-based process. We used CH3NH3 Pb(I(1-x)Br(x))3 (x = 0.1-0.15) as the absorbing layer and poly(triarylam… Show more

“…Both of these methods are based on a similar principle‐different solubility of MAPbX 3 (X = Cl, Br, I) in different solvents 99, 100, 101, 102, 103, 104, 105. For example, hybrid halide perovskites show good solubility in DMSO, DMF, and GBL, while they show non or low solubility in chlorobenzene, benzene, diethyl ether, etc.…”

“…Therefore, developing novel preparation methods to achieve high‐quality tin perovskite film is of great importance to boost both efficiency and stability of Sn‐based PSCs. In lead‐based perovskites, the methods for morphology engineering include addition of additives,157, 158, 159 solvent engineering,160, 161 vacuum engineering,162, 163 thermal annealing,164 self‐healing,165 vapor deposition,166 and so on. Herein, the reported methods used for preparing high‐quality tin perovskite layers are introduced.…”

“…Solvent engineering technique has been proved many times as the most effective method for preparing high‐quality lead perovskite films to achieve high‐performance PSCs 160, 161, 168, 169, 170. The work on solvent engineering of Sn‐based perovskite was first reported by Hao et al,47 where they investigated the solvent effects on the crystallization of the MASnI 3 perovskite films.…”

“…Herein, inspired by study of Jeon et al that PbI 2 –DMSO–MAI can be converted into MAPbI 3 ,8 Seok and his colleagues proposed that DMSO molecules in PbI 2 –DMSO were also able to be simply exchanged via FAI molecules due to stronger interaction of FAI–PbI 2 (ionic interaction) compared to DMSO–PbI 2 (molecular interaction). They utilized this intramolecular exchange method and prepared superior FAPbI 3 perovskite layer with large grain sized morphology and prior crystallization along (111) crystal orientation, thus resulting in corresponding perovskite solar cell with the highest PCE to date 9…”

“…In 2013, Julian et al used sequential deposition method to attain optimized morphology of perovskite layer and the PCE of the device reached up to 14.1% 7. Late in the same year, a PCE of 16.2% was achieved by applying hybrid halogen elements of perovskite layer 8. Recently, a record PCE of 20.1% was reported by Korean Research Institute of Chemical Technology (KRICT),9 which has already been certified by National Renewable Energy Laboratory (NREL) in late 2014,10 showing the remarkably rapid developments of PCE over just five years (illustrated in Figure 1 a) 11…”
