One of the key components missing at the time to make those batteries more than a mirage, where the lack of proper flexible solar panels. For some time there has been "bendable" panels available, but those where still attached to quite thick substrate.
|Actual cells in use. Not too curvy, these are!|
The substrate is normally made of glass, not flexible, in solar panels. Substrate can also be made of special polymers (plastics) for thin film solar panels that are more or less flexible. The major new development, as far as I understand, is that the substrate is no longer necessary for the cells to function and thus can be removed. These new PV cells can be applied to non special materials and could give product designers new freedoms in adding powers sources to their products without compromising in their designs.
Maybe this technology could be used to produce tear off pages in a booklet for DIYers to stick on any odd project laying around? Sign me up for a couple!
Happy New Year!
