Abstract
The effects of three commonly-used precursors for preparing CsPbI3 thin films, namely DMF solutions of PbI2 and CsI (type A), DMF solutions of PbI2 and CsI with hydroiodic acid (type B), and DMF solutions of so-called “HPbI3” and CsI (type C) on the properties of Inorganic CsPbI3 films and devices were detailed discussed here. Based on our experimental results and analyses, the nature of HPbI3 could not be simply assigned to DMAPbI3. The best precursor among them is the type C, which used HPbI3 totally replacing PbI2 in the DMF solvent. Finally, a best device with planar configuration of FTO/compact(cp)-TiO2/CsPbI3/Spiro-OMeTAD/Au was fabricated, exhibiting a PCE of 8.15% with VOC of 0.883 V, JSC of 13.4 mA cm−2 and FF of 68.9%. Our discussions here would help other researchers who are concerned in the field of inorganic perovskite CsPbI3 to clarify the puzzles of these three similar but totally different precursors and the debates of the nature of HPbI3.
