The efficiency of photovoltaic generators based on different semiconductor materials with optimized band gaps can achieve considerably higher values than those obtained with single junction solar cells. A new type of a concentrating system is presented which allows high concentration and simultaneously splitting of the spectral region. This dispersive and concentrating (DISCO) system is based on volume phase transmission holograms which exhibit minimum absorption, high diffraction efficiency and adjustable dispersion. The spectral imaging properties of volume phase transmission holograms can be optimized in respect with the requirements for solar applications. An essential tool for this optimization process is the theoretical and numerical description of volume phase holograms.
