Research Professor in Solar Energy and Opto-electronics at Swansea University.Current research interests include thin film photovoltaic (PV) research, transparent conducting oxides (TCOs), MOCVD of II-VI semiconductors, in-line deposition of thin film coatings for thin film PV, PV module fabrication, inkjet printing of metal contacts, characterisation of PV devices and PV modules. Interest in the fundamental mechanisms of MOCVD include reaction kinetics, precursor chemistry and nucleation mechanisms. The PV research entails innovative methods for improving PV module efficiency such as light management and extending the spectral range of PV devices. Monitoring of PV systems is aimed at exploring methods for extracting more energy under different climatic conditions. Other aspects of research into PV performance include long term degradation mechanisms and carbon footprint of PV module manufacture. Professor Irvine has a particularly interest in novel PV materials and devices for Building Integrated PV (BIPV) systems and PV for space applications.
Dan is the SPARC II project manager. In this role, Dan coordinates project management across the whole SPARC II consortium and provides technical leadership and engages in research activities on some aspects of the research programme. One of Dan’s current areas of research interest is high-power, low-weight, flexible thin film photovoltaics for space application. He has conducted research in collaboration with the University of Surrey, Qioptiq Space Technology and Surrey Satellite Technology Ltd leading to the first reported direct deposition of a thin film solar cell onto 100-micron thick space qualified cover glass. Most recently, Dan has collaborated with the Surrey Space Centre and the UK and Algerian Space Agencies to build a flight demonstrator of the CSER solar cell which is now orbiting the earth as part of the AlSat Nano mission. The solar cell on-board AlSat Nano feeds back live data on the cells performance and give this innovative technology all important space heritage.
Senior Research Officer
Andy is currently working on thin film tin sulphide (SnS) photovoltaics (PV) using a prototype inline metal organic chemical vapour deposition (MOCVD) reactor. He also works on transparent conducting oxides (TCOs) using a large area inline MOCVD system and is currently focused on aluminium doped zinc oxide (AZO), as well as using zinc oxide (ZnO) as a resistive barrier layer. Andy is working towards an Earth abundant non-toxic solar cell device and has interests in the investigation of suitable n-type buffer/window layers for an effective p-n junction in a SnS-based solar cell. Other interests include the CVD approach for fabrication of perovskite films for improvement of structure stability and long term performance of solar cells using tin halides. Andy has designed and built a gas delivery system for perovskite CVD, with use of metal organic chemical precursors and capability for industrial scale-up. He has also established a robust platform process for thin film cadmium telluride (CdTe) PV with tight control on all MOCVD process parameters from substrate to solar cell device. This included development of ultra-thin CdTe solar cells, working towards reducing material consumption and production costs for commercial manufacture.
