Project Description

In recent years perovskite materials in solar cells have shown dramatic increases in power conversion efficiency. They have the potential to overtake silicon solar cells as the commercially dominant solar cell technology. However, some challenges remain before this can become a reality. Perovskite solar cells have the potential to be significantly cheaper than silicon cells to produce because they can be processed from solution. In order to reliably produce large areas of perovskite thin films in a continuous thin film it is necessary to better control the deposition process. Slot die casting is fast becoming the technology of choice for depositing perovskite thin films. Therefore, this project will focus on studying the physical and chemical processes occurring during the deposition of perovskite ink by slot die coating. The PhD student will build an instrumented slot die coating system that enables them to use optical microscopy to observe the perovskite crystallization process on the microscale. They will also apply for experimental time at the Diamond Light Source x-ray facility to conduct in situ wide angle x-ray scattering measurements so that they can follow the crystallization process in real time at the nanoscale.
This will predominantly be an experimental project and the student will receive training in materials characterisation, instrument development, solar cell fabrication and testing. Experimental techniques that will be used include slot die deposition, scanning electron microscopy, atomic force microscopy, ellipsometry, UV-vis spectroscopy and electrical characterisation of solar cells. They will attend several conferences both national and international in order to present their work.
