项目摘要
In FY2022 the fellow worked on several research projects and supervised two PhD students. In particular, she worked on three projects: the first focuses on the passivation of the perovskite layer using phenethyl ammonium-halide molecules with the aim to understand the mechanism of these molecules on the perovskite surface, specifically taking into account different perovskite compositions and the effect of different halides (iodine, bromine and chlorine). It is in fact well known in literature that these passivation molecules improve both stability and device performance, but there is no unanimous agreement on the chemical mechanism. The second project focuses on developing new deposition methods for the commonly used self-assembly molecule (2PACz), used as hole transporting material in p-i-n device configuration. This is usually spin-coated and this deposition methos has shown to be effective in making high performing devices but does not allow a uniform coverage on large area devices. We therefore show that alternative deposition methods can be employed, such as thermal evaporation and spray-coating techniques, with the latter being particularly effective for high or even higher device performances compared to the traditional spin-coating method. The fellow also tried to fabricate large area devices (area 22.4cm2) but the performances of control devices remain low due to difficulties in depositing part of the device on large area. The third project is at early stages and involves new electron transporting molecules to be used as self-assembly molecules.
在2022财年,他参与了多个研究项目,并指导了两名博士生。特别是,她从事了三个项目:第一个项目侧重于使用苯乙基卤化铵分子对钙钛矿层进行钝化,旨在了解这些分子在钙钛矿表面的机理,特别是考虑到不同的钙钛矿成分和不同卤化物(碘,溴和氯)的影响。事实上,文献中众所周知,这些钝化分子可以提高器件的稳定性和性能,但对其化学机理并没有一致的看法。第二个项目的重点是开发新的沉积方法,用于常用的自组装分子(2PACz),作为p-i-n器件配置中的空穴传输材料。这通常是自旋涂覆的,这种沉积方法已被证明在制造高性能器件方面是有效的,但不允许在大面积器件上均匀覆盖。因此,我们表明可以采用替代沉积方法,例如热蒸发和喷涂技术,与传统的旋转涂层方法相比,后者对于更高甚至更高的器件性能特别有效。该研究员还尝试制造大面积器件(面积22.4cm2),但由于难以在大面积上沉积部分器件,控制器件的性能仍然很低。第三个项目处于早期阶段,涉及用于自组装分子的新型电子传递分子。
