Perovskite crystallization for stable and large scale printable solar cells

The project aims at obtaining fundamental insights in the processes that govern perovskite thin film formation and crystallization for photovoltaic applications. Crystallite size, crystallite orientation, surface coverage, surface roughness and interaction with the receiving surface are crucial parameters that determine the solar cell performance. One of the principal issues in perovskites currently revolves around stability. The significant strides made in recent time provide the opportunity to comfortably think of large scale deployment.

Scale-up of printing technology to GWp/a scale, necessary to impact global energy systems, requires intimate knowledge on the crystallization processes and their dependence on process conditions. Using a range of in-situ spectroscopic and X-ray diffraction techniques the mechanisms and kinetics of crystallization of organometal perovskite layers will be investigated in real time during film formation. This will provide guidelines to develop large scale and fast roll-to-roll printing processes for this promising new energy technology.
