The Technology
The NanoPower Window system involves covering windows with thin films of silicon nanoparticles, which act as photovoltaic solar cells – absorbing ultraviolet light and converting it into electrical current. The process doesn’t significantly affect the transparency of the window, and requires no major changes in manufacturing infrastructure. The silicon nanoparticles are produced by a patented electrochemical and ultrasound process. They are identically sized, (1 to 4 nanometers in diameter), and provide varying wavelengths of photoluminescence and high quantum efficiency of 50% to 60%.

Until now, the weak link in the process was the application of the particles on to the glass. Octillion previously relied on manually constructed, purpose-built, custom electrospray system elements. By replacing them with less costly, commercial components, Octillion has made the process faster and more cost-effective.

“This advancement allows us to speed-up one of the most important steps in development of our NanoPower Window technology, and certainly helps better prepare for the transition from the lab towards larger-scale testing and production,” explained Mr. Nicholas S. Cucinelli, President and CEO of Octillion Corp. “This new ability to integrate off-the-shelf components in the deposition process is promising and indicative of a path towards building a lower-cost production technology.”
