0001 The invention relates to the development of an enhanced luminescent solar concentrator panel employing a unique method for capturing and concentrating the maximum amount of solar energy in a specific area using an "inverse" focusing effect. The solution involves a luminescent solar panel that absorbs all incident energy without dispersion in the opposite wall (no semitransparency). 0002 This type of enhanced luminescent solar concentrator operates with sunlight and consists of a transparent material, an intermediate zone made up of a diffusive layer and multiple internally reflecting and focusing cones, a horizontal discontinuous reflective layer beneath the cones, a second reflective layer at the panel's base, and photovoltaic strips positioned along the lateral edges of the transparent portion. 0003 Sunlight striking the panel is diffused by the pigment and trapped underneath through a funnel-shaped zone directed by an inverse optical lens. Thanks to reflection between the intermediate layer and the lower reflective base of the panel, the trapped light remains concentrated and is transferred by reflection to the photovoltaic elements. 0004 This invention is innovative because it enables the creation of an enhanced luminescent solar concentrator (LSC) panel that absorbs the majority of incident energy while reducing losses. This application is highly effective as it can be used as a cladding for opaque surfaces (non-glazed) for green energy generation, and i
