Patrick is working on the design and development of transparent conducting oxide electrical contacts for thin-film solar cells.  The primary focus of his research is band gap engineering and manipulation of the electrical properties of p-type metal oxides.

Patrick graduated with a 2:1 MSci in Geoscience from the University of Durham in 2008, and obtained an MSc in Engineering Geology from Newcastle Unviersity in 2010.

A key part of any solar cell is the top electrical contact.  This needs to be both electrically conductive and optically transparent so as to enable maximum current extraction whilst simultaneously maximising transmission of incoming light to the photoactive layers.  This project involved the investigation and further development of existing n-type transparent conducting metal oxides, in particular aluminium-doped zinc oxide, as well as design and development of various copper based p-type metal oxides.  The project aimed to produce a range of effective materials for use in a variety of different cell types and architectures, and to maximise cell efficiencies by reducing electrical and optical losses.  A key area involved investigation of methods for overcoming the inherent low mobility issue in p-type metal oxides, including the synthesis of very highly doped materials, alloying and exploration of modulation doping.
