Abstract
This invention concerns a grouped nanostructured unit system forming a metamaterial within the silicon and the manufacturing process to arrange them therein in an optimal manner. The nanostructured units are grouped and conditioned in an optimal arrangement inside the silicon material. The process comprises the modification of the elementary crystal unit together with the stress field, the electric field and a heavy impurity doping in order to form a superlattice of nanostructured units grouped in an optimal arrangement so as to improve the efficiency of the light-to-electricity conversion by means of efficient use of the kinetic energy of hot electrons and efficient collection of all electrons generated within the converter.
