Innovalight is developing light-activated power generating products based on a unique and patented solvent-based silicon nanomaterial platform. Innovalight claims that it has a cost savings over traditional silicon products by using less silicon and having a more efficient manufacturing process as well as having some unique optical advantages. It is a start-up company aiming to take advantage of the rising cost of solar cells that are based on monocrystalline or polycrystalline silicon as the price of these traditional solar products continues to rise.
Innovalight solution-processes the quantum dots in a so-called silicon "ink" that lends itself to proven manufacturing technology using roll-to-roll printing technology used for printing on paper or film. Being able to deposit ink on flexible substrates allows Innovalight to apply its technology to applications such as clothing and portable chargers for both consumer and military customers.
By controlling the sizes of the dots from 2 to 10 nm the company can tailor either the absorption or emission spectra of the resulting film. This allows capture of everything from infrared to ultraviolet and the visible spectrum in between which is not possible with conventional technology.
The technology is also capable of being used as a very efficient emmiter or light source. By controlling the particle size you can emmit light of any color or a combination of particle sizes that will give off white light.
Innovalight is an early-stage technology start-up company based in Santa Clara, California.
Their technology is similar in some respects to others that are developing thin-film silicon photovoltaics. Kyocera, Unaxis , Ovonics, Sanyo, Energy Photovoltaics , Konarka, Nanosys and Nanosolar are companies in this field that I have written posts about. It seems with all these companies and all the companies developing non-silicon thin-film products, a few should emerge as leaders with low cost solar products.
