A deposition process developed at the National Renewable Energy Laboratory (NREL) is a key technology for creating a new type of solar cell: a film-based cell consisting of a layer of highly aligned crystalline silicon (c-Si) deposited on a flexible metal substrate. The process could marry the best features of c-Si solar cells and thin film solar cells, resulting in efficient and inexpensive solar modules that are also flexible and lightweight.

In 2008, Innovalight, a start-up company in Sunnyvale, California, invented a liquid form of silicon, called Silicon Ink. It contains silicon nanoparticles that are suspended evenly within the solution. Those nanoparticles contain dopant atoms that can be driven into silicon solar cells, which changes the conductivity of the silicon and creates the internal electric fields that are needed to turnphotons into electrons -- and thus into electricity. The ink is applied with a standard screen printer, already commonly used in the solar industry. The distinguishing feature of Silicon Ink is that it can be distributed in exact concentrations in precisely the correct locations on the surface of the solar cell. This allows most of the surface to be lightly doped, enhancing its response to bluelight, while heavily doping the area around the electrical contacts, raising the conductivity in that area to allow the contact to work more efficiently. The accuracy and uniformity of the ink distribution allows the production of solar cells that achieve higher power production at a minimal additional cost.
