NOVELTY - The system (310) has an outer cladding layer surrounding an air cladding layer, where the outer cladding layer allows penetration of ambient light and serve as a protective layer. An exit port is located proximate to an end of a fiber optical waveguide. Multiple PV cells or solar cells are fixed at the exit port of the fiber optical waveguide. The fiber optical waveguide guides light to the solar cells. Cross-sectional area of an active core of the fiber optical waveguide represents a majority of cross-sectional area of the fiber optical waveguide.    USE - Photovoltaic (PV) system.    ADVANTAGE - The system includes a fabric constructed from fiber optic waveguides, where one of the fiber optic waveguides hosting material configured to absorb and emit light, and the fabric is configured to guide the light to the solar cells for conversion of electrical energy that is stored in energy storage elements, so that the storage elements are configured to provide power to a mobile electronic device via a plug or an outlet. The system has solar ribbons that absorb light guided at the exit ports of the waveguide and generate electricity. The system has effective area in which the waveguide is illuminated, and the solar cells are located at the exit ports of the waveguide requires a narrow matrix of the solar cells to gain solar energy, thus improving efficiency of the solar cells in a system. The guided light at the exit ports of the waveguide structure represents light from an entire structure at the exit port with high intensity, thus allowing the system to operate under very low light level conditions to generate electrical signal. The exit ports have high efficiency of capturing light and maximize difference in refractive index of the light between the core and a cladding.    DETAILED DESCRIPTION - The fiber optical waveguide is a telecommunications fiber. An INDEPENDENT CLAIM is also included for a fiber optical waveguide.
