Resumen

The present invention relates to a solar cell and to a method of manufacturing thereof, the solar cell comprising: a layer of an n-doped semiconductor, a layer of a p-doped semiconductor and an intermediate band layer being disposed between the n-doped and the p-doped semiconductor layers, the intermediate band layer comprising: an amorphous semiconducting host material, a plurality of colloidal quantum dots embedded in the host material and substantially uniformly distributed therein, each quantum dot comprising a core surrounded by a shell, the shell comprising a material having a higher bandgap than that of the host material, and a plurality of metal nanoparticles embedded in the host material and located at least in a plane where a plurality of quantum dots are distributed.
