Semiconducting Covalent Adaptable Networks as Interfacial and Charge Transporting Materials for Advanced Photovoltaics
The current proposal deals with the interface issues in perovskite solar cells. The project focusses on the development of innovative interfacial and charge transporting materials for these devices. Covalent adaptable networks as bifunctional soft materials ensuring simultaneously the role of the interfacial passivation layer and the extraction and transport of holes will be designed, prepared and characterized in detail. In particularly, we focus on vinylogous urethane vitrimers. Molecular hole transporting building blocks will be designed by inspiring from carbazole based molecular glasses. Targeted molecules and materials will be firstly prepared and characterized in detail both in solution and thin film. In the next step, the bifunctional materials will be deposited on the perovskite thin film and characterized. Finally, the full solar cell devices will be assembled, and their photovoltaic output (device performance and long-term stability) will be evaluated.
