However, the ratio module's cost/energy produced remains a major issue for classical photovoltaic energy. Many technologies have been developed to solve this problem, by using micro-or nanostructuring on the solar cell or on the module. These kinds of structuring are often used as antireflection and light-trapping tools. In the meantime, other solar technologies are considered, such as concentration photovoltaic modules. This article presents a module combining both approaches, that is, nanostructures and concentration, in order to increase the module's profitability. Sol-gel derived TiO 2 diffraction gratings, made by dynamic interferometric lithography, are added on the top of the glass cover to deflect unused light onto the solar cell, increasing the module efficiency. %G English %2 https://ujm.hal.science/ujm-01514970/document %2 https://ujm.hal.science/ujm-01514970/file/Journal%20of%20Nanomaterials.pdf %L ujm-01514970 %U https://ujm.hal.science/ujm-01514970 %~ UNIV-ST-ETIENNE %~ UNIV-SAVOIE %~ IOGS %~ UGA %~ CNRS %~ INPG %~ LAHC %~ PARISTECH %~ IMEP-LAHC %~ LMGP %~ INC-CNRS %~ UDL %~ TEST-HALCNRS %~ UGA-COMUE %~ USMB-COMUE %~ TEST2-HALCNRS
