The future of solar power?

Improved 3D printing can ‘revolutionise’ industry

Following the news that a company has been given £2m funding to develop ‘solar glass’, technology that allows buildings to produce their own low-carbon electricity through their windows, the future of the solar industry looks even brighter thanks to the potential of 3D printing.

Printing 3D solar cells has an advantage over the standard method of PV models because they are less complex to create, weight less and do not need direct overhead sunlight to absorb the UV energy. Studies have also shown that 3D cells can be 20% more efficient than standard flat solar panels, according to researchers at the prestigious Massachusetts Institute of Technology (MIT).

Another benefit of 3D solar cells is cost. It has been estimated that production of 3D cells would be 50% cheaper than traditional panels because it would eliminate inefficiencies associated with wasting materials. Also, as 3D printing can take place anywhere, shipping costs will be reduced considerably. 

On top of this, 3D printing of solar cell is not limited to one form. Solar cells can be added to things ranging from glass, paper and even fabric, meaning that solar cells creating by 3D printing can be used in more advanced ways compared to traditional methods of creating solar panels.

With the potential of 3D printing starting to gain momentum within technology circles, it seems that solar power, something that has stuttered somewhat in recent years, could finally have a way of becoming a major player in the renewable energy industry.

'Solar glass' lets buildings generate own power

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.
