Understanding the Role of the Electron Selective Contact in Perovskite Solar Cells
Perovskite solar cells (PSC) have generated excitement in the field of emerging photovoltaics due to their high efficiencies, easy manufacturability and low cost. Over the last few years it has become clear that the electron selective layer is critical to the performance of perovskite solar cells. PSC have made large increases in efficiency, but there are still problems with long term stability. A number of researchers have shown that organic contacts can be used to drastically reduce JV hysteresis in PSC, but it has also been observed that the hysteresis reappears as the cell ages. This project will focus on better understanding the role of these selective contacts in perovskite solar cells – it will involve materials preparation, making complete solar cells and characterisation using a wide range of techniques (including AFM, SEM, XRD, PL and µ-SR). We also have the scope to look at non-standard perovskite materials with enhanced water stability and to work with the project partners to carry out long term stability testing on new devices. The studentship is in the Department of Chemistry at the University of Bath. For more information on what to expect as a CDT-PV student then please see our CDT-PV Handbook that can be downloaded from the CDT-PV website. The supervisory team includes Dr. Petra Cameron and Dr. Simon Lewis at the University of Bath. To apply for this studentship, send your CV to Dr. Petra Cameron (firstname.lastname@example.org) before the 20th January 2017. Please also contact email@example.com if you require any further information. To be eligible for the award a student must have no restrictions on how long they can stay in the UK and have been ordinarily resident in the UK for at least 3 years prior to the start of the studentship.
