Photoactive Semiconducting Biopolymers. The basic aims of this project are to elucidate, manipulate, and utilise the unique chemical and physical properties of a class of biopolymers called the melanins.

Enhancing the performance of thin-film photovoltaic cells via the application of luminescent down-shifting layers. Photovoltaic (PV) devices convert sunlight directly into electricity. For decades, the dominant PV technology has been based on thick, costly silicon wafers. However, due to higher energy conversion efficiencies and manufacturing processes, thin film PV cells can provide lower price than of the conventional wafer-based technologies. This project takes one of the leading thin film ....Enhancing the performance of thin-film photovoltaic cells via the application of luminescent down-shifting layers. Photovoltaic (PV) devices convert sunlight directly into electricity. For decades, the dominant PV technology has been based on thick, costly silicon wafers. However, due to higher energy conversion efficiencies and manufacturing processes, thin film PV cells can provide lower price than of the conventional wafer-based technologies. This project takes one of the leading thin film technologies and couples it with a passive optical layer, which will result in a 30% performance enhancement by overcoming internal absorption losses. It is anticipated that the increased performance will enable the thin film PV technology to be far more commercially viable and attractive for future commercialisation, and hence reduce the cost of solar power.Read moreRead less

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
