Screen-Printed Solar Cells: Be Green Fashionably

Solar panels don’t fit in any environment, so this might be a solution: these printed solar cells will provide a different look to your solar setup. They are translucent and it is even possible to print text on them – is this going to spawn a new generation of solar powered billboards on highways? This is also suitable for homes because they could even be inserted into windows (ok – that’s a little extreme).

There’s a downside, the efficiency is only 4% – which is really low. Usually silicon-based cells convert around 25% of the sun’s energy, if I remember correctly.
