Abstract: The paper discusses options for the design of concentrator photovoltaic modules with reduced structural heights; those options are based on trade-offs between reducing the Fresnel lens optical efficiency, changing the profile of the light power distribution in the focal spot, and ensuring the required (permissible) misorientation angles at the pre-specified average geometric concentration in the lens-solar cell pair.

Keywords: Fresnel lens, multijunction solar cell, average geometric sunlight concentration, misorientation angle.
