Abstract: The invention relates to an innovative solution for producing solar energy based on nanoparticles. The invention has an efficient design and has a low cost per generated watt, and is based on the principle of multiple chambers for multispectral capture provided with optical concentrators and a novel antireflective coating capable of absorbing the light spectrum, from ultraviolet rays to infrared rays, independent of the angle of incidence of the ray. The photovoltaic cells can consist of organic and/or inorganic thin-films deposited by grafting particles using ion or plasma beams and/or printed on the cells by piezoelectric inkjet or laser printing. The invention covers methods for improving the deposition surface and relates to an efficient, high-yield direct logistics flow roll-to-roll system, as well as to real-time quality control during the production (figure 1). Using a nanometric preparation of CIGS/CIS in the form of an ink or a powder for visible rays, doped layers of TiO 2  are formed for trapping ultraviolet (UV) rays and/or infrared (IR) rays and are applied by inkjet, laser and/or continuous rotary printing on any rigid or flexible substrate. Other innovative aspects of the invention include an increase of the overall yield thanks to the flattening of the deposited or printed layers, either by laser or by a chemical processing of the surface receiving the solar rays for the CIGS/CIS layers. The device is capable of following the sun and thus generates electricity at a high yield. The device respects cleanliness and environmental restrictions and is designed for producing clean electricity without toxic elements. The device has a favourable energy ratio as it can compensate for the energy required for the production thereof in a few days (fig. 2 to 10). The invention can be used,  inter alia , for the household and industrial fields. The product has a general form of rigid or flexible panels or discretely deployable films providing energy for generating electricity. Due to the flexible structure and lightweight properties of the invention, it can easily be integrated into buildings or into the bodywork of cars as well as into vehicles travelling outside Earth's atmosphere. Moreover, a variant of the invention can be used for converting calories into piezoelectric current and/or into WiFi, OE or OS wave current, thereby ensuring providing wireless energy transfer.
