Abstract: A photovoltaic system consists of a waveguide body, luminescent dyes and a photovoltaic cell. Luminescent dyes and their aggregated particulates with larger diameter are dispersed in the waveguide body to scatter light and transform the first light of the external light into a second light, wherein the wavelength of the second light is longer than the wavelength of the first light. Compared to conventional techniques, the use of luminescent dyes of the present invention can be aggregated into particulates with larger diameter to enhance the power conversion efficiency of the photovoltaic cell, without providing a scattering layer, in order to reduce the production cost and the element complexity of the photovoltaic system. A manufacturing method for a photovoltaic system is also disclosed.
