Young Investigator Group 'Hybrid Materials Formation and Scaling’

The BMBF-funded Young Investigator Group started on March 1st 2017. Scalable deposition methods for high-quality semiconductors such as metal-halide perovskites and an in-depth understanding of film formation.

Characterization of large area thin films with spacially-resolved methods: PL microscopy image on half-degraded MAPbI3 sample from collaborators at Lund University.

Metal-halide perovskite based solar cells have emerged as a promising cost-effective photovoltaic technology. Scaling material deposition to application-relevant areas is a mayor research and development challenge that our group will address. As deposition methods, our group’s focus are scalable deposition methods such as slot-die coating and inkjet printing, which we will optimize for the deposition of metal halide perovskite semiconductors. This includes development of precursor inks, optimization of coating and printing process conditions and the realization of larger area metal halide perovskite modules. For understanding thin film growth and analyzing larger area metal halide perovskite layers, we are developing tools for in-process monitoring of processing steps and employ mapping as well as imaging methods. Within the HySPRINT Innovation Lab, we aim to realize larger area tandem modules, which requires the development of larger area metal halide perovskite modules with band gaps matching the bottom cell absorber.
