摘要：

A model for the thermal properties of holographic planar concentrators on module performance is presented and verified with experimental data. The holographic planar concentrator modules consist of ribbons of volume holograms placed next to photovoltaic cells to achieve a low level concentration effect. The holographic ribbons increase the surface area required to produce a fixed amount of output power but reduce the cost of the module by eliminating approximately half of the photovoltaic cell material, in this case monocrystalline bifacial silicon cells. Due to the low concentration, the temperature reduction effect of the added surface area overcomes the added heat provided by the holograms. The theoretical point at which the added concentration by holograms overcomes the cooling effect provided by the extended region for varying theoretical holographic contributions is also presented.
