Ultra-thin solar cell is flexible enough to wrap around a pencil
Flexible, thin-film solar cells are widely considered the future of power generation.
The solar cell is made from the semiconductor gallium arsenide and then stamped directly on a flexible metal substrate without using an adhesive, which would have added thickness. The cell was fused with the electrode on the substrate by using a cold welding process where pressure was applied at 170 degrees Celsius. The metal bottom layer also acted as a reflector to direct light back towards the solar cell.

......interesting, both the temp and that the film is 1 micrometer thick
