New invention adds solar cells to glass panels that can produce low-carbon electricity
An energy company has been given a £2m funding boost after developing a form of glass that can absorb solar energy.
A University of Oxford spin-off, Oxford Photovoltaics, believe the funding will help them take the remarkable product to the commercial market. The ‘solar glass’ works by adding a very thin layer of transparent, solid-state solar cells to glass, which can then turn up to 12% of solar energy into low-carbon electricity. This means that a new building can use this glass for all of their windows and run a large portion of the building’s electricity needs from it.

This is why Kevin Arthur, the company’s founder and CEO, believes the product can be a commercial success. ‘What we say here is rather than attach photovoltaics to the building, why not make the building the photovoltaics? If you decide to build a building out of glass, then you've already decided to pay for the glass. If you add this, you're adding a very small extra cost, no more than 10%’.
Glass panels for buildings usually cost about £600 to £1000 per square metre, and adding the solar glass would only cost about £60 to £100 extra. This would only be a small additional cost, as the glass would then generate electricity for the new building. The company is mostly targeting customers creating new buildings throughout 2013, but can also retrofit existing buildings with their technology.
