Gaining control over the deposition and single-crystal growth of lowdimensional hybrid perovskites to determine structure-property relationships for optoelectronic applications (Research)

In recent years hybrid organic-inorganic perovskites (HOIPs) have received significant research attention mainly because of their use as the active layer in perovskite solar cells (PSC). After the rise of the 3D HOIPS for use in PSCs, the lower dimensional 2D hybrids are currently receiving increased attention. These 2D HOIPs consist of an organic layer, sandwiched between inorganic layers. In order to establish structure-property relationships and improve solar cell devices, we need to elucidate the exact structures of these 2D HOIPs. However, the crystallization of these systems shows structural diversity, depending on the crystallization methods, thin film deposition techniques, solvents, etc. used. Therefore, this project focuses on uncovering the details of the crystallization process to enable a deep understanding of the fundamental triggers of the growth mechanism acting on the formation of these 2D HOIPs.
