Abstract
This communication presents a preliminary study and a prototype of a holographic solar concentrator where both focusing and dispersive properties of holographic optical elements are exploited. In such a concentrator, the image of the sun is chromatically dispersed and projected on a photovoltaic cell array ; each cell corresponds to a specific band of the solar spectrum. This configuration insures the matching between the spectral response of the cells and the solar spectrum. Due to this matching, the photovoltaic cells can work in optimal conditions, that is, with maximum energy efficiency. The aim of this work is to underline the different problems and perspectives of such a realization. The problems are connected to chromatic aberrations, amplitude of dispersion, diffraction efficiency, stability in time, etc.
