    摘要： The complex comprising one or more of the compound represented by general formula: RPb n1 X m1 (wherein R is a cation represented by R 1 NH 3 + (wherein R 1 represents a univalent substituted or unsubstituted hydrocarbon group), or the following formula:

    (wherein R 2 represents a hydrogen atom, or a univalent substituted or unsubstituted hydrocarbon group); X is the same or different, and each represents a halogen atom; n1 is 0.8 to 1.2; and m1 is 2.8 to 3.2, or the compound represented by general formula: R 2 Pb n2 X m2 wherein R and X are as defined above; n2 is 2.8 to 3.2; and m2 is 7.7 to 8.3; and one or more dimethylformamide molecules is capable of decreasing the stirring time upon dissolution in an organic solvent such as DMSO, as well as decreasing the hysteresis and improving the solar cell characteristics (in particular, photoelectric conversion efficiency) when the complex is applied to a perovskite layer. Further, by using a perovskite material substantially free from lead halide, it is possible to improve the power conversion efficiency (PCE) and the internal quantum efficiency (IQE).

    摘要： A system and method for fabricating a perovskite film is provided, the system including a substrate stage configured to rotate around its central axis at a rotation speed, a first set of evaporation units, each coupled to the side section or the bottom section of the chamber, a second set of evaporation units coupled to the bottom section, and a shield defining two or more zones having respective horizontal cross-sectional areas, which are open and facing the substrate, designated for the two or more evaporation units in the second set. The resultant perovskite film includes multiple unit layers, wherein each unit layer is formed by one rotation of the substrate stage, and the composition and thickness of the unit layer are controlled by adjusting at least the evaporation rates, the rotation speed and the horizontal cross-sectional areas.
