Here is the MIT site about it:
http://web.mit.edu/newsoffice/2011/printable-solar-cells-0711.htmlYou can download a PDF file about it.
The only process they did is making the foldable electrodes.
The real PV material is still an expensive step via vapour deposition probably
done in a vaccuum chamber, so it is no real homemade cell as one needs expensive
vaccuum equipment.
Also the conversion efficiency is only at 1 % right now...
But maybe they could open source this so many more people could work on this ?
Are the US universities forced to put their research into the open source,
if it is funded by tax payer money as it is in Europe ?
Well we need better any easier solar cells that can really be printed by cheap printers
or being just a paint being put on graphite paper or simular easier cells.
