... account for the aperture width of the concentrator, the geometric concentration ratio, rim-angle, and misalignment of the receiver, characterized by the radial and angular offsets. The Latin Hypercube Sampling (LHS)-based ray-tracing method was used. Validation of the method was performed by comparing...

... resulted in a 275% gain in the concentration ratio and a 72.5% reduction in the spherical aberration compared to the original lens of the same aperture diameter and number of facets. The performance of both novel and original Fresnel lenses when used as solar concentrators with a conical coil receiver...

... in detail. The optimum values of the design parameters for low, medium, and high concentration ratio BDPTCs are reported. An online tool for quickly estimating γ is also launched in this paper. While evaluating Eq. (8) , if the roots are imaginary, the ray does not intercept the secondary concentrator...

..., increased efficiency and stationary operation. The acceptance angle of a CPC is associated with its geometrical concentration ratio, by which the size of PV cell could be reduced. Truncation is a way to increase the actual acceptance angle of a mirror CPC, but it also reduces the geometrical concentration...

... large aperture and high concentration ratio of PETAL render the direct characterization of its optical performance a nontrivial task. We have applied a variety of methods in order to assess PETAL ’s optical quality. These include imaging the full moon and Jupiter at night, and analysis of the 3-D...
