OLEDs May Generate Electricity

Posted by timothy on from the another-step-toward-off-grid-computing dept.

It turns out, however, that if you apply light to these devices, you can get them to produce electricity; in other words, they will run backward...'"

    A friend of mine has been working on organic solar cells for the last 4 months (MSc Project), he's hoping to reach 4% efficiency. Last time I spoke to him he was just about to put the ITO transparent contacts on, then test it with different wavelengths of light.

    The possibilities of making organic solar cells have been considered almost as long as organic LEDs have been known (one of my professors was in the Cambridge group who discovered the effect) but the efficiency will probably never be near that of good polycrystaline silica.

    To power my laptop I'd need half a metre square of high grade solar cell, about £500...
