Solar Driven Hydrogen Generation with Dye-Sensitised CuCrO2 Photocathodes
… to fossil fuels. Inspired by natural processes, dye-sensitised photoelectrochemical cells provide a platform for H2 generation from water. Fuel-forming photocathodes are currently limited by the small range of wide-bandgap p-type semiconductors available. The majority of previous reports have …

Integration of liquid crystals with redox electrolytes in dye-sensitised solar cells
… mixtures, and their potential application in dye-sensitised solar cells (DSSCs). The birefringence of LCs causes light modulation, which can be controlled by an applied voltage and electric field. In particular, the LCs are used as one of the components for the electrolyte redox couple which …

Efficiency Improvement of Cross-Compound Parabolic Concentrator for Silicon and Dye-sensitised Solar Cells
… ratio was integrated with third-generation dye-sensitised solar cells (DSSCs) by directly synthesising the solar cell onto the concentrator’s receiver. Initially, to assess the impact of CCPC integration, silicon solar cells were integrated with CCPCs using UV adhesive and evaluated under …

Photocatalytic degradation of pharmaceuticals in aqueous solutions and development of new dye sensitised photocatalytic materials
… to this, composite materials based on TiO2 and dye molecules have been developed in the hope of developing solar/visible light activated photocatalysts. A visible light sensitised photocatalyst based on the porphyrin tetra-(4-carboxyphenyl)porphyrin was successfully developed. This composite was …

Green Photochemistry: The synthesis of fine chemicals with sunlight
This research examines the dye-sensitised photooxygenation procedure as a case study to demonstrate ‘green’ photochemistry. There are three main streams to the research, namely the optimisation of juglone (5-hydroxy-1,4-naphthoquinone) synthesis under green conditions, the extension of the …
