Abstract: The present disclosure relates to a transparent luminescent solar concentrator (LSC). The LSC according to an embodiment of the present disclosure includes a polymer resin panel uniformly doped with phosphors. Accordingly, it is possible to greatly improve the transmittance and optical haze compared to the existing LSC manufactured by physically mixing or coating phosphors on the front side of the panel. In addition, it is possible to greatly improve the light collection efficiency of the LSC through the arrangement structure of the solar cells embedded in the polymer resin panel. The polymer resin panel according to an embodiment may be manufactured with flexibility or rigidity according to the purpose of use, and thus can be widely applied to curved structures, for example, building windows, automobile glasses and greenhouse roofs.
