Summary
Metal halide perovskites (MHPs) have been in the spotlight of scientific research for over a decade due to their remarkable properties and performance in solar cells. Their future relies on a deeper understanding of their fundamental properties, better control of their structure, and implementation by scalable deposition methods. While most research efforts are dedicated to the solution processing of MHPs, vapour deposition holds many benefits. It is a solvent-free, scalable method of high industrial relevance offering high throughput, homogeneity, material economy, safety, yield and controllability. Despite these clear advantages, the development of engineering approaches to precisely control the properties of MHPs by vapour deposition remains in its infancy. In PEROVAP, I will develop novel routes for engineering MHPs by vapour deposition and the fundamental understanding of their growth and crystallisation, thus enabling new material structures with tailor-made properties. I will establish structural control over the phase, orientation and microstructure of MHPs by additive engineering, and develop a new class of perovskite-organic hybrid semiconducting composites. I will also demonstrate efficient, controllable n- and p- electrical doping of vapour deposited MHPs and create graded MHP layers with tailored optoelectronic properties and energetic landscape. To realise this, I propose a unique combinatorial fabrication-characterisation methodology for their in-situ spectroscopic characterisation. This approach will allow to efficiently explore the multi-dimensional parameter space required to engineer the MHP properties, and enable the development of the fundamental understanding of the film formation processes. Finally, to reveal the structure-property relations, the engineered MHPs will be integrated in novel solar cell architectures. The approaches developed in PEROVAP will open a new path for MHP electronics and optoelectronics far beyond state-of-the-art.

Metal halide perovskites (MHPs) have been in the spotlight of scientific research for over a decade due to their remarkable properties and performance in solar cells.
