My research broadly encompasses Energy Materials & Devices, in two main areas:
I lead Swansea's "Materials-Hub" as part of the WEFO funded SPARC II project, and as part of the SPECIFIC-IKC (EPSRC EP/N020863/1) and Sêr Solar programs, my research area focuses on solution processed photovoltaic materials and device physics. My PV research group utilizes time & frequency domain techniques such as Intensity Modulated Photovoltage Spectroscopy (IMVS) or Transient Photovoltage Decay, to characterize carrier transport, recombination and mobility in photovoltaic devices.
Two new projects were started in October 2018. The first will develop ultra-light weight flexible tandem silicon/perovskite solar cells in collaboration with IQE plc. The second (EPSRC EP/R032750/1) is a collaboration between Materials Engineering and Computer Science to develop the next generation of novel perovskite powered IoT devices. I am also very excited to be involved with the SUNRISE GCRF (EP/P032591/1) project with the aim to rapidly accelerate and prove low cost printed PV for use in off grid Indian communities.
I lead SPECIFIC's newest research activity on novel solution processable thermoelectric materials and devices, focusing on organic and hybrid materials. See our latest work in Advanced Materials on thin film SnSe thermoelectric generators.
