Development of large area perovskite solar cells
The last few years has seen tremendous progress in the development of photovoltaics devices based on perovskite materials. Such materials can be processed from solution into thin-films, offering the prospect of manufacturing efficient photovoltaic-devices over large areas using comparatively cheap materials and processes, in which the amount of embodied energy (and carbon) is substantially reduced. This PhD project will develop a range of new perovskite precursor ’ink’ formulations, and will then explore their deposition over large areas using a range of techniques, including slot-die coating and ultra-sonic spray-coating. Both such techniques offer the prospect of device fabrication at low cost over very large areas and are of significant interest in real-world manufacture processes. The objective of the project is to create devices having areas of 10’s or 100’s of square cm that operate with power conversions efficiencies of > 10%. In your studies, you will use a number of techniques to explore device operation, efficiency, homogeneity and yield. This is an experimental research project suitable for Physicists, Material Scientists, Electronic Engineers or Physical Chemists who wish to build a career in the fields of photovoltaics and renewable energy.
