“…Solar energy utilizations lead to no emissions of harmful gases and dust, and are thus valued by many researchers. Solar energy resources can be used in many application fields, for instance, heat storage [32][33][34], thermal power generation [35,36], photovoltaic electricity production [37,38], hybrid photovoltaic-thermal utilization [39][40][41], freshwater production [42][43][44][45], multi-energy complementary utilization [46][47][48][49] and hydrogen production [50][51][52].…”

For achieving carbon neutralization and promoting the coordinated development of solar and coal-fired power generations in the context of energy transition, this paper develops a public–private partnership project including the government, carbon exchange enterprise, solar thermal power plant and a coal-fired thermal power plant. Using the four-party evolutionary game theory method, the evolutionary stable strategies are evaluated. The influence estimate results of key factors show that a higher carbon emission penalty and a green electricity subsidy as well as a lower carbon trading tax rate will be beneficial to the carbon trading market, as well as facilitate carbon neutralization. In most instances, the government and carbon exchange enterprise can hold acceptable participating intention. For relatively suitable reference value ranges, the carbon emission quota sale price range of the solar thermal power plant sold to the carbon exchange enterprise is 5.5~6.0 USD/t, that of the carbon exchange enterprise sold to the coal-fired thermal power plant is 5.0~6.5 USD/t, that of the solar thermal power plant sold to the coal-fired thermal power plant is 5.0~5.5 USD/t, that sold to the coal-fired thermal power plant by outside organizations is 9.0~10.5 USD/t, and the carbon trading tax rate range is 6.0~6.2%.

“…Among the types of concentrators used in the design of LCPVs [6], this work will focus on the small-scale linear Fresnel reflector (SSLFR). In addition to having a lower manufacturing cost than other solar concentrators, they showcase a well-proven technology that has been the subject of multiple studies (see [7][8][9][10], for instance). These reflectors concentrate the sunlight onto a secondary system by means of a row of longitudinal mirrors.…”

A New Two-Foci V-Trough Concentrator for Small-Scale Linear Fresnel Reflectors

et al. 2023

We present the design of an original secondary cavity for use in Small-Scale Fresnel Reflectors in photovoltaic applications. The cavity is similar to the classical V-trough, but the primary reflector system is configured so that there are two focal points on the aperture. The rays coming from each side of the primary system reach the opposite side of the cavity, producing a non-symmetrical distribution of the irradiance. This modifies the acceptance half-angle and allows us to break the maximum limit for the concentration ratio of ideal symmetric concentrators. Our study is analytic, and we provide formulas for any number of reflections. Numerical simulations with a ray-tracing program based on MATLAB are included. We provide a comparison of optical concentration ratio, height and cost parameter between our system and two classical designs with a single focal point: the V-trough and the Compound Parabolic concentrators. This way, we verify that our design yields better concentration ratios while keeping the ray acceptance rate at one. Our solution proves to be better than both the classical one-focus V-trough and the Compound Parabolic concentrator. Specifically, the proposed solution is significantly better than the classical one-focus V-trough in optical concentration ratio, with an increase between 15.02 and 35.95%. As regards the compound parabolic concentrator, the optical concentration ratio is always slightly better (around 4%). The height of the cavity, however, is notably less in this design (around 54.33%).

“…The reflector concentrator with a Fresnel lens − or a parabolic mirror , is commonly used to improve light-harvesting of solar cells. − Solar concentrators are categorized into low (<10×), medium (10–100×), high (100–2000×), or ultrahigh (>2000×) depending on light concentration . Such a concentrating photovoltaic system is effective to increase the solar cell output power.…”

Dye-sensitized solar cells (DSSCs) are attractive due to their simple fabrication process, low cost, performance stability, and eco-friendly characteristics. The power output (P out ) can be improved by applying an external concentrator, but this is rarely applied because of increasing temperature. Here, we successfully increased the P out of bifacial DSSCs with the V-shaped plane, and concave mirrors showed an improved power output (P out : 6.42 and 24.31 mW/cm 2 , separately) compared to ones without mirrors (4.25 mW/cm 2 ). The high surface temperature on the concave mirror can be reduced with 1 cm mirror distancing followed by a reduction in P out (19.07 mW/cm 2 ).
