In Episode Four of the University of Bath’s Research with Impact podcast, Roland Pease heads to the roof of the Chancellors' Building to discuss the future of solar energy with experts leading the way at the University of Bath.

In this episode he meets:

Professor Alison Walker from Bath's Department of Physics. Alison’s research concerns multiscale modelling of perovskite solar cells and organic devices such as displays. In 2019, she chaired the Solar Commission whose aim was to show how UK innovation and industrial capabilities could be harnessed to allow the UK to be a global player in solar in the years ahead. The report was launched in the House of Lords. She directs the 7 university Centre for Doctoral Training in New and sustainable photovoltaics, CDT-PV. Locally, students funded by the CDT-PV worked with Bath Abbey to explore how could be installed on historic buildings to reduce emissions.

Professor Petra Cameron from Bath's Department of Chemistry. Her group researches energy materials and makes perovskite solar cells. She focuses on understanding ion motion in perovskites (perovskites are mixed electronic-ionic conductors), making perovskite solar cells with carbon coatings for water splitting to make solar fuels. This is about making perovskites more stable to help scale up their production. Her work has helped to position the University as somewhere of real solar energy expertise and has also helped to put the UK to the forefront of perovskite development.
