The basic aim of this project is to assess the viability of using semiconducting biopolymers from the melanin family of macromolecules in photoactive device based applications. In order to do this, key optical, structural, electronic, and photochemical properties will be assessed on thin films in the solid state. The melanins are the only known semiconducting biopolymers, and are non-toxic, biocompatible and biodegradable. Their use as ?active? materials in solid state or photo-electrochemical devices has never before been suggested. Specifically, these materials could be used as the light harvesting components in dye sensitised Gratzel cells, or, as the donor material in soft solid photovoltaic junctions. The melanins are also a key class of biomolecules (their involvement in skin cancers is well documented), and hence, any advancement in our understanding of their functions and properties could have biological importance.Read moreRead less

This project aims to develop a multi-functional solar-thermal desalination device to simultaneously produce clean water and electricity. Interfacial solar evaporation-based desalination technology has the unique advantage of using solar light as the sole energy source for affordable clean water production.
