NOVELTY - Three-dimensional array for solar power generation comprises solar compressor sandwich assemblies, each solar compressor sandwich assembly including: (a) first and second photovoltaic cell arrays, each array comprising photovoltaic cells (2); and (b) a solar compressor (1) sandwiched between the first and second photovoltaic cell arrays so that the solar compressor has internal faces adjacent the first and second photovoltaic cell arrays, and narrow faces extending between the internal faces.    USE - The three-dimensional array is used for solar power generation (claimed).    ADVANTAGE - The edge(s) of the solar compressor is/are exposed to daylight and the received solar photon energy is deflected off of the reactive surface of the solar compressor onto the photovoltaic cells, where even with a reduction in energy output of around 20% as the depth of the array increases, there is a marked gain in output for the same area as a flat two dimensional array of the same footprint area.    DETAILED DESCRIPTION - Three-dimensional array for solar power generation comprises solar compressor sandwich assemblies, each solar compressor sandwich assembly including: (a) first and second photovoltaic cell arrays, each array comprising photovoltaic cells (2); and (b) a solar compressor (1) sandwiched between the first and second photovoltaic cell arrays so that the solar compressor has internal faces adjacent the first and second photovoltaic cell arrays, and narrow faces extending between the internal faces. The solar compressor is made from any optical material, either clear or opaque, with a suitable light transmittance value; of any thickness; and either solid or hollow in construction. The internal faces have a light reactive finish formed by media blasting, random grinding, grinding, or acid etching, where the light reactive finish is arranged to permit a portion of light entering the solar compressor to be reflected at the internal faces and a remaining portion of light entering the solar compressor to be transmitted through the internal faces to the first and second photovoltaic cell arrays. The solar compressor sandwich assemblies are arranged so that light can enter each solar compressor via one or more of its narrow faces.
