NOVELTY - Fabricating a solar cell module (1), comprises: (a) providing a solution having a luminescent dye; (b) mixing the solution with a first waveguide material to obtain a first mixture; and (c) placing the first mixture and a second mixture having nano-powder and a second waveguide material into a mold to form a waveguide body (10) having a first layer body and a second layer body stacked on first layer body. The waveguide body has a top surface (10a), a bottom surface (10b) opposing to the top surface, and a lateral surface (10c) connecting the top surface with the bottom surface.    USE - The method is useful for fabricating a solar cell module.    ADVANTAGE - The method: has decreased production complexity; is of low cost; provides a solar cell module with many layers, more flexibility, and having a enlarged light reception area and higher collecting efficiency; and is capable of controlling the luminescent dye and position.    DETAILED DESCRIPTION - Fabricating a solar cell module (1), comprises: (a) providing a solution having a luminescent dye; (b) mixing the solution with a first waveguide material to obtain a first mixture; and (c) placing the first mixture and a second mixture having nano-powder and a second waveguide material into a mold to form a waveguide body (10) having a first layer body and a second layer body stacked on first layer body. The waveguide body has a top surface (10a), a bottom surface (10b) opposing to the top surface, and a lateral surface (10c) connecting the top surface with the bottom surface. At least a solar cell is disposed in the mold and embedded in the waveguide body. An INDEPENDENT CLAIM is also included for a solar cell module, comprising: a waveguide body having a first layer body and a second layer body stacked on the first layer body, where the first layer body has a first waveguide material and a luminescent dye, the second layer body has a second waveguide material and nano-powder, and the waveguide body has a top surface, a bottom surface opposing to the top surface, and a lateral surface connecting the top surface with the bottom surface; and at least a solar cell embedded in the waveguide body.
