Abstract

Cylindrical asymmetrical nonimaging concentrators with receivers based on fin absorbers immersed in dielectric rhombuses are introduced and shown to be ideal. They have the same concentration factor as dielectric filled devices but require only a small amount of dielectric around the absorber. The asymmetric shape and nontracking property of the collectors allow their arrangement in flat panels that, integrated with a supporting thermal insulator, may be the roof or the wall of a small building situated in a remote locality. This would passively satisfy the electric requirements of the building.
