Nanosolar prints solar cells and assembles panels to enable the most cost-efficient solar electricity. Nanosolars proprietary approach to printing CIGS (Copper, Indium, Gallium, Selenium) and nanoparticle inks using an annealing process minimizes the use of expensive, high vacuum deposition manufacturing equipment. This allows the Company to utilize equipment from the industrial printing and roll-to-roll manufacturing industries to produce solar-electric foil at high speeds, bringing the economics of printing to the world of solar PV semiconductor manufacturing.
