Abstract
The present invention relates to a plasma texturing method for silicon based solar cells and the nanostructured silicon solar cells produced thereof. The silicon based solar cell comprises a silicon substrate having in at least part of its surface conical shaped nanostructures having an average height between 200 and 450 nm and a pitch between 100 and 200 nm, thereby achieving low reflectance and minimizing surface charge recombination.
