All screen-printed 18% homogeneous emitter solar cells using high volume manufacturing equipment

The Innovalight Cougar™ Platform is a portfolio of simple to implement technologies that, when combined with Innovalight Silicon Ink, enables the manufacture of a selective emitter solar cell with a non-masking single-step diffusion. Cell efficiencies of up to 19% have been achieved. Innovalight Silicon Ink is a highly engineered silicon nanoparticle colloidal dispersion, implemented for both high volume ink-jet and screen deposition, and further optimized to be produced and delivered in commercial volumes [1].
