the high cost of the solar cell, a concentrator system is needed for generation
of more solar energy by solar cell to increase effectiveness and reduce cost.
Fresnel lens could perform efficiently under large aperture optical system;
therefore Fresnel lens was usually applied to the solar concentrator system.
The genetic algorithm was integrated with the commercial program
LightTool to design a non-imaging Fresnel lens. First several test functions
were applied to verify the genetic algorithm. Then the search for optimal
geometry parameter setting of Fresnel lens was conducted for maximization
of energy effective and reduction of optical loss.
