| Popis: | 95 This thesis first part describe the Fresnel Lens apply to solar cells. The simulation 3D Dome-shaped on concentrator ratio 25X. For an acceptance angle of a = 1.5 deg and collection efficiency with 96.8%. Tolerate angle and discussion absorption efficiency and tolerance angle in different wavelength. Second part describe the Fresnel Lens apply to solar lighting system. For an acceptance angle of a = 0.2 deg and collection efficiency with 60%. We designed better efficiency of the visible light greater than ultraviolet light and infrared light on concentrator lens. Therefore the optical fiber absorb lesser ultraviolet light and infrared light, and discussion absorptive efficiency and incident angle of light guide on visible light. This thesis first part makes the Lens, the simulation as compared with product result, energy diagram and efficiency of solar energy spectra. Under sunlight, the focus point size is 3mm and we got a higher efficiency of visible light region. |
