A concept developed by Head of Photonics Professor Stephen Sweeney offers a solution to the energy consumption crisis being driven by the internet age. With internet traffic growing at 60 per cent a year, today’s telecommunications and data networks are being put under increasing strain, requiring cooling systems that consume large amounts of energy – which contributes significantly to the world’s carbon footprint. Working with other members of a major EU-funded project, Head of Photonics Professor Stephen Sweeney is developing a...

A new class of disordered photonic materials has demonstrated the first isotropic photonic band gaps and freeform waveguiding. The field of photonics which enables control over the generation and propagation of light has advanced tremendously through the development of micro and nanostructured photonic materials. An important class of such materials is represented by photonic band gap (PBG) materials that prohibit light propagation in a certain frequency band for all directions and polarizations. A PBG is the photonic analogue of the electronic band gap in a semiconductor, and is key in...

A new mobile app, designed by academics at the University of Surrey, will radically change the way visitors interact with museums and gallery spaces. The technology will not only enhance the visitor experience through additional ‘augmented reality’ content including a mixture of audio and visual materials, but will also offer an innovative way for curators and owners of smaller galleries and exhibitions to track how visitors are interacting with exhibits. The project team, which has combined computing and tourism academics from the University, has successfully trialled the...

Professor Ravi Silva of the University of Surrey’s Advanced Technology Institute has identified the range of combinations of organic and inorganic materials that will underpin new 4th generation solar cell technology – opening the door for more efficient, cost-effective and larger scale solar power generation. Solar power – the greenest form of renewable energy – is in increasing demand across the world, with the global capacity for solar power generation now topping 100GW. The new 4G solar cells defined by Professor Silva are a hybrid that combine the low cost and...

At the opening keynote address at the 10th International Conference on Nanoscience and Nanotechnology (NN13), held in Thessaloniki, Greece, Professor Ravi Silva from the Advanced Technology Institute at the University of Surrey outlined his definition for 4th generation (4G) solar cell technology to an enthusiastic and receptive audience filling the conference hall.  4G Solar cells based on ‘inorganics-in-organics’, offers improved power conversion efficiency to current 3rd Generation (3G) Solar Cells, while maintaining their low cost base. The 4G solar cells defined in this...
