The group has a primary research interest in the understanding and development of low cost, large area photovoltaic technologies.
The group's research interest is multi-interdisciplinary with a particular focus to study fundamental photophysics and optoelectronics of disordered semiconductors - the working principles and loss-mechanisms - for use in photonic device concepts; aiming to elucidate design principles that enable technological development.
Light driven electron and energy transfer reactions on relevant timescales, and electronic response of device, are studied by employing time resolved and steady state optical and optoelectrical spectroscopic techniques to explain the relationship between device property and molecular structure. These techniques offer a broad spectrum of analytical tools that have proved vital in analysing disordered solar cells.
We have many collaborations, including with experts on innovative material synthesis, modelling and morphological studies. Current collaborators are: University of Potsdam, Imperial College London, Chinese Academy of Sciences, South China University of Technology, University of Queensland.
Recent research highlights include exploring the interplay between charge transfer states and free carriers on bimolecular recombination, the role of charge carrier mobility in charge photogeneration of light harvesting systems, and explaining why some organic semiconductors allow for substantially thicker active layers; a highly desirable quality for future commercialization.
