A solar power company capable of ‘printing’ colourful glass that can generate electricity from the sun’s energy announced a £2m funding boost on Tuesday.

Oxford Photovoltaics, a spin-off from the University of Oxford, said the investment from clean-tech investors MTI Partners will help its solar glass, which can be dyed almost any colour, take a step closer to the commercial market.

‘What we say here is rather than attach [solar] photovoltaics to the building, why not make the building the photovoltaics?’ Kevin Arthur, the company’s founder and CEO, told the Guardian. ‘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. [The solar cell treatment] costs no more than 10% of the cost of the facade.’

These generally cost between £600 and £1,000 per square metre, meaning the new cell treatment wouild cost just £60-£100 extra per square metre.

The technology works by adding a layer of transparent solid-state solar cells at most three microns thick to conventional glass, in order to turn around 12% of the solar energy received into low-carbon electricity. The power can then be exported to the national grid or […]
