The invention involves the development of an enhanced luminescent concentrator solar panel using a specific method to capture and concentrate the maximum percentage of solar energy. The solution is a luminescent solar panel that absorbs all incident energy without dispersion on the opposite side (no semi-transparency). This enhanced luminescent solar concentrator operates with sunlight and is made up of a transparent material, a specific distribution of composite pigment consisting of diffusive and reflective elements with an intermediate layer reflecting solar light, photovoltaic strips positioned at the lateral edges of the transparent portion, and a reflective base. Solar light incident on the panel is diffused by the pigment and trapped in the underlying part through a funnel-shaped region and the reflection between the intermediate layer and the lower reflective base of the panel. The trapped light remains concentrated and is transferred to the photovoltaic elements through reflection. This invention is innovative because it allows for the creation of an enhanced luminescent concentrator solar panel (LSC) that absorbs the majority of incident energy, reducing losses. This application is highly effective as it can be used as a coating for opaque surfaces (non-glass) in green energy generation. These results are achieved without the need for expensive materials or equipment, thanks to the synergies among the constituent parts, making it ready for immediate industrializatio
