Mathematical modelling of dye-sensitised titania solar cells: a route to improved efficiency in production. Dye-sensitised titania solar cells (DSCs) provide a technically and economically credible alternative to silicon photovotaic devices. Increasing the efficiency of commercially produced DSCs to 12% from the current production cell efficiency of 6%,will result in significantly lower delivered energy costs than the current alternative photovoltaic devices. This project will develop a mathemat ....Mathematical modelling of dye-sensitised titania solar cells: a route to improved efficiency in production. Dye-sensitised titania solar cells (DSCs) provide a technically and economically credible alternative to silicon photovotaic devices. Increasing the efficiency of commercially produced DSCs to 12% from the current production cell efficiency of 6%,will result in significantly lower delivered energy costs than the current alternative photovoltaic devices. This project will develop a mathematical model of a DSC as a first stage in the development of a decision support capability for the manufacture of more efficient DSC's. The model will extend existing models to incorporate full transport modelling and side-reactions in the electrolyte and will be validated by experimental work.Read moreRead less
Enhancing the Understanding and Performance of Passivating TiO2 Coatings for Photovoltaic Devices. Titanium dioxide (TiO2) has been widely used as an antireflection coating in the silicon (Si) photovoltaics industry as it exhibits excellent optical properties and low deposition cost. However, recently manufacturers have been turning to alternatives such as hydrogenated silicon nitride coatings that exhibit greatly improved electronic properties, but cost 4 - 10 times more to deposit. This proj ....Enhancing the Understanding and Performance of Passivating TiO2 Coatings for Photovoltaic Devices. Titanium dioxide (TiO2) has been widely used as an antireflection coating in the silicon (Si) photovoltaics industry as it exhibits excellent optical properties and low deposition cost. However, recently manufacturers have been turning to alternatives such as hydrogenated silicon nitride coatings that exhibit greatly improved electronic properties, but cost 4 - 10 times more to deposit. This project seeks to understand the fundamental limitations behind the poor surface passivation afforded by TiO2 to a Si wafer, and subsequently develop a passivating TiO2 coating that can reduce the cost of electricity generated by Si solar cells.Read moreRead less
