Design and analysis of solar-tracking 2D Fresnel lens-based two staged, spectrum-splitting solar concentrators

In this study, we investigated a spectrum control method that improves the uniformity of concentration flux and changes the direction of energy that temperature is likely to generate by Fresnel lens (FL). This design is mapped by the ray tracing method based on Snell's law and the reflection law of the lens, spectral splitter, and secondary reflector. In order to investigate the illumination pattern on the receiver of the spectral splitting collector consisting of FL and two dichroic mirrors, a spectral allocation algorithm has been developed that can define a three-point coordinate set of prisms on all the lenses . . Coordinates are then ported to TracePro for FL creation and light path validation. The study also investigated an appropriate second stage composite plate concentrator to recover radiation outside the target range. Acrylic-based FL computer simulation determines the maximum energy available under the lens. Published measurement data has been used to calibrate the results before being used to plot the position of the spectral segment on each target. In this research, we can investigate the details of the spectral composition in various places through adjusting the target position, and help to adapt the various focused wavelengths to the appropriate application.

One of the most common uses of Fresnel lenses is the collection of sunlight. This is considered to be very close in parallel (infinite conjugate system). Concentration with Fresnel lens is ideal for converging on photovoltaic cell and heating surface. For example, Fresnel lenses can be used for general home maintenance, such as home and pool heating. In these cases, the total surface area of ​​the lens determines the amount of light collected. Although it is common for solar applications, Fresnel lenses are very suitable for applications requiring cheap, thin and lightweight positive lens parts. Although Fresnel lenses are not novelty, their popularity has been increasing due to improvements in manufacturing techniques and materials. Fresnel lenses are truly unique optical lenses, making it an ideal tool for a variety of interesting and interesting optical designs.

Solar energy is one of the most promising renewable energy sources and is very important for sustainable development of energy. This paper presents a new type of solar concentrator with focus Fresnel lens. The design principle of the solar concentrator was demonstrated and the spectral collection performance was simulated by Monte Carlo ray tracing (MCRT) and compared with the linear Fresnel lens. The results showed that spectral concentration uniformity and optical efficiency of the Fresnel lens by focusing are better than those of linear focusing Fresnel lenses. At the same time, analyzing some characteristic parameters of Fresnel lens concentrators with different focusing conditions, the result of the optical efficiency of the concentrating solar power generation (CPV) system is to focus the Fresnel lens concentrator from a high ratio Can be improved. In the middle.
