Solar light concentration photovoltaic conversion system using a wavelength splitter and lambda-specific photovoltaic cells optically coupled to lambda-dedicated fibers illuminated by respective split beams

摘要

A solar light concentration photovoltaic conversion system, uses a solar light collector to focus collected light onto a termination of at least one multi-fiber cable. A wavelength splitter is optically coupled to the other termination of the multi-fiber cable for producing light beams of different wavelengths, each illuminating the optical termination of one or more lambda-dedicated tap fibers or multi-fiber cables. From the wavelength splitter depart a number of lambda-dedicated groups of tap fibers adapted to convey the radiation to remotely arranged lambda-specific photovoltaic cells, configured for efficiently converting light energy of the specific wavelength spectrum carried along respective fiber or group of fibers into electrical energy. The lambda-specific photovoltaic cells are formed onto light spreading structures optically coupled to a respective tap fiber or multi-fiber cable, adapted to trap the injected light and convert it into electricity.
