Semiconductive nanocristalline inks: revolution start from here?

inchiostri-semiconduttoriThe active part of the photovoltaic silicon cell is extremely thin compared to the thickness of the cell itself. The part polarized in reverse doping of the substrate, which allows the photovoltaic effect of separating charges is actually less than 300A, a third of a micron compared to the approximately 200um of normal thickness of the photovoltaic cell.

This is known, but this aspect has aroused some years now, the chance to explore semiconductor inks that appropriately treated on poor materials for the substrate, permit the construction of photovoltaic paint.

This aspect is well known, the novelty instead derives from the fact that some new inks based on the compound Cu2ZnSnS4 (CZTS) (Copper Zinc Tin Sulfur) allows to obtain a nanocrystalline film that can be applied with very low cost process and will allow a considerable reduction of the costs of the cell thus obtained. It is most likely that during 2015 some important
