Description
Organometallic perovskite solar cell has been considered as one of the most attractive and promising next generation solar cells due to its superior photoelectric properties including low-cost fabrication potential based on solution process After Miyasaka's report of 3.9% power conversion efficiency (PCE) in 2009, it has developed rapidly and reached a highest PCE of 26.02% by Seok in 2023. In this system, the PCE of devices critically depends on the crystallinity of the organometallic perovskite layer. Therefore, most effort was devoted to control the film to obtain high quality perovskite film under various fabrication conditions. To understand and control film formation process, in-situ measurement techniques were applied in perovskite films. First, the thermal in-situ annealing results will be presented. Secondly, the in-situ measurement results during spin-coating process will be presented, especially in the anti-solvent free system. All these in-situ measurements were performed using synchrotron x-rays and GIWAXS (Grazing Incidence Wide Angle X-ray Scattering) technique.
