Concepts towards the next generation of dye-sensitised solar cells: tandem and plasmonic solar cells. This project aims at exploring the feasibility of novel device concepts to enhance the performance of dye-sensitised solar cells. These concepts include tandem solar cells as well as novel energy relay systems based on the ability of nanoparticles to effectively act as antenna systems that can funnel energy towards a sensitising dye molecule.
Innovative high-efficiency hybrid technology for commercial solar cells. The purpose of this project is to develop improved photovoltaic devices of significantly higher efficiency and lower cost than conventional screen-printed solar cells. This in turn will contribute to greatly reduced electricity costs from non fossil-fuel based sources.

Summary
Hydrogen passivation mechanisms in silicon solar cells. This project aims to understand hydrogen passivation mechanisms in silicon solar cells. Most silicon solar cells use low-quality wafers with defects that can reduce performance by >10%. Commercial devices use hydrogen to passivate defects and improve performance. Despite decades of research, these passivation mechanisms are controversial and industrial methods are ineffective. This project will investigate hydrogen charge-state control and ....Hydrogen passivation mechanisms in silicon solar cells. This project aims to understand hydrogen passivation mechanisms in silicon solar cells. Most silicon solar cells use low-quality wafers with defects that can reduce performance by >10%. Commercial devices use hydrogen to passivate defects and improve performance. Despite decades of research, these passivation mechanisms are controversial and industrial methods are ineffective. This project will investigate hydrogen charge-state control and transient hydrogenation processes, and correlate reaction rates and material properties. This should improve the understanding of hydrogen passivation mechanisms and lead to more effective hydrogenation processes that potentially reduce greenhouse gas emissions and the cost of sustainable electricity.Read moreRead less

Advanced Recombination-based Loss Analysis Methods for Solar Cells. Photovoltaic (PV) solar cells are too expensive to become a viable solution for the challenges facing humanity. Increasing solar cell efficiency can reduce the cost of PV-generated power. Improved efficiency requires the ability to identify and quantify loss mechanisms, many of which are recombination related.

Photovoltaic (PV) solar cells are too expensive to become a viable solution for the challenges facing humanity. Increasing solar cell efficiency can reduce the cost of PV-generated power. Improved efficiency requires the ability to identify and quantify loss mechanisms, many of which are recombination related. Thus, innovative analysis methods need to be developed to facilitate improved understanding and identification of various loss mechanisms. The project aims to investigate recombination processes that deteriorate solar cells performance, using a novel measurement system in combination with advanced simulation tools.

Passivating Cadmium free Cu2ZnSn(S,Se)4 solar cell by contact engineering. The project aims to develop new solar cells made of low cost abundant elements. The cells are cadmium-free copper zinc tin sulphide (CZTS) cells formed by rear contact passivation and damage-free evaporated front layers. CZTS has the same efficiency potential as current commercial copper indium gallium selenide (CIGS) cells, but consists of low cost, abundant elements.

The project aims to develop new solar cells made of low cost abundant elements. The cells are cadmium-free copper zinc tin sulphide (CZTS) cells formed by rear contact passivation and damage-free evaporated front layers. CZTS has the same efficiency potential as current commercial copper indium gallium selenide (CIGS) cells, but consists of low cost, abundant elements. Concepts and methods will be developed for passivation of CZTS solar cells via both back and front contact engineering. The cadmium- free buffer layer will be investigated and the application of CZTS will be expanded. This work may be applied to CIGS improvement and could give CZTS materials a significant role in the rapidly growing photovoltaic industry.Read moreRead less

This project aims to enhance understanding of the interface science associated with charge-transfer reactions at nanostructured semiconductor surfaces. Experimental and modelling approaches will be used to unravel the contributions of surface wetting and nanostructure geometry to the kinetics of charge transfer reactions at the surfaces. Expected outcomes include an enhanced capacity to engineer nanostructured semiconductor surfaces for designed functionality and an extended collaborative network which can collectively address significant problems in energy science. It is anticipated that these outcomes will be realised in reliable, low-cost metallisation for silicon photovoltaics and increased power densities for electrochemical storage systems.Read moreRead less

The science and engineering of defects and impurities in photovoltaic silicon. This project will create the knowledge and techniques that are essential to make low-cost, impure silicon suitable for producing highly efficient solar cells. This will help to drive down the cost of solar electricity, since the silicon material itself is a significant component of the overall cost of most photovoltaic modules.
