New hybrid CPV\/PV modules, that use innovative solar tracking strategies, allow using new optics solutions to overcome the limitations related to the sun incidence angles on the module, thus simplifying the optical design.<\/p>\n<p>&nbsp;<\/p>\n<p>In this contribution, a new solar concentrator for innovative hybrid CPV\/PV modules using aspherical and non-radial symmetric lens is simulated and experimentally tested. These optics exploit the asymmetry in the kinematics of the tracking system along the two orthogonal tracking axes, allowing to get light transmittance higher than 80%, within the 300 &#8211; 1800 nm spectral range, despite the inevitable infrared absorption and the absence of AR coating.<\/p>\n<p>&nbsp;<\/p>\n<p>The solar concentrator only consists of a single thin primary lens in PMMA, with a geometric concentration factor of 400X. The lens shape was designed and optimized for multiple incidence angles, to maximize performance at various operating conditions with acceptance angle ranges of \u00b117\u00b0 and \u00b15\u00b0, in the two orthogonal directions.<\/p>\n<p>&nbsp;<\/p>\n<p>The optical system, mounted on a test bench, was characterized indoor with a quasi-collimated Xenon lamp, and the results were in good agreement with the simulations. The new optics represents a promising solution for the development of next-generation PV modules, characterized by high energy yields, low costs and reduced environmental impact.<\/p>\n","scarica_file":false,"link_estreno":[{"link_text":"Download Publication","link":"https:\/\/www.spiedigitallibrary.org\/conference-proceedings-of-spie\/13014\/130140A\/Design-and-characterization-of-innovative-asymmetrical-optics-for-high-performance\/10.1117\/12.3029580.short"}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2024-04-11","autori":"F.
