Paper Abstract

The fundamental idea of this new type of solar concentrator consists in the use of con-vergent lens, which on concave face (exposed toward the Sun) has an infrared reflecting layer, what determines the formation of a spherical mirror for this spectral range; a visible range is concentrated by lens in classical manner. Thermal or photovoltaic receivers with optimum performances, for these spectral bands can be placed in respective foci. In the case of thermal receivers, selective surfaces for narrow spectral bands could be achieved by a less sophisticated technology. Use of these concentrators for photovoltaic receivers would allow manufacturing of manyspectral photovoltaic converters. A mathematical model which takes into account spectral and geometrical characteristics of concentrators and receivers has been elaborated for performances evaluation by computing simulation.
