Photovoltaic devices or solar cells are provided. More particularly, the present invention provides photovoltaic devices having IR and/or UV absorbing nanostructured layers that increase efficiency of solar cells. In some embodiments the nanostructured materials are integrated with one or more of: crystalline silicon (single crystal or polycrystalline) solar cells and thin film (amorphous silicon, macrocrystalline silicon, CdTe, CIGS and III-V materials) solar cells whose absorption is primarily in the visible region. In some embodiments the nanoparticle materials are comprised of quantum dots, rods or multipods of various sizes.
L'invention porte sur des dispositifs photovoltaïques ou sur des cellules solaires. Plus particulièrement, l'invention porte sur des dispositifs photovoltaïques possédant des couches nanostructurées IR et/ou d'absorbtion des UV qui augmentent l'efficacité de cellules solaires. Dans certains modes de réalisation, on intègre aux matériaux structurés des cellules solaires de silicium cristallin (monocristallin ou polycristallin) et ces cellules solaires de film mince (silicium amorphe, silicium macrocristallin, CdTe, CIGS et matériaux III-V) dont l'absorption se trouve principalement dans la zone visible. Dans certains modes de réalisation, les matériaux nanoparticulaires sont constitués de points quantiques, de tiges ou de multipods de différentes dimensions.
