NOVELTY - A solar system comprises refraction array including at least one refraction sub-array, and converting array including broadband converting cells. The refraction sub-arrays include refraction sites. The refraction sites refract variable approach-angle collimated solar radiation into solar rays. The solar rays are different waveband, where refraction site directs each of solar ray. The different direction is at least dependent on the approach-angle of the solar radiation. The converting array is positioned such that light refracted by refraction array impinges on the converting array.    USE - Solar system for converting solar radiation into electric energy.    ADVANTAGE - The solar cell exhibits different bandgap energy value, thus absorbing photons of different wavelengths. The sub-cells are disposed in order of increasing effective band gap energy, with sub-cell having lowest effective band gap energy being closest to substrate.    DETAILED DESCRIPTION - The solar system comprises refraction array including at least one refraction sub-array, and converting array including broadband converting cells. The refraction sub-arrays include refraction sites. The refraction sites refract variable approach-angle collimated solar radiation into solar rays. The solar rays are different waveband, where refraction site directs each of solar ray. The different direction is at least dependent on the approach-angle of the solar radiation. The converting array is positioned such that light refracted by refraction array impinges on the converting array. The converting cells receives solar rays of specific waveband originating from different refraction sites and arriving from different directions, where photovoltaic cells include crystalline material, amorphous material, organic synthetic material, and mixed phase material. An INDEPENDENT CLAIM is included for a method for converting solar radiation into electrical energy comprising refracting variable approach-angle collimated solar radiation; receiving refracted solar rays by broadband converting cells, and converting specific waveband refracted solar rays into electrical energy.
