Optical and thermal performance of a uniaxial bidirectional tracked linear‐focusing Fresnel lens solar concentrator.
Publication Type: Academic Journal
Source(s): International Journal of Energy Research. 10/25/2022, Vol. 46 Issue 13, p18768-18780. 13p.
Abstract: Summary: The focal length of linear‐focusing Fresnel lens changing with incident angle is unavoidable, which goes against high‐efficient solar energy collection. This paper proposes a uniaxial bidirectional tracked linear‐focusing Fresnel lens solar co...
Performance optimization of the hybrid HDH‐RO desalination system powered by photovoltaic‐thermal modules using solar dish concentrators.
Publication Type: Academic Journal
Source(s): International Journal of Energy Research. Sep2022, Vol. 46 Issue 11, p14946-14963. 18p.
Abstract: Summary: The lack of pure water and electricity in remote regions pushes to simulate of an innovative high‐productive hybrid desalination system with the lowest power consumption rates, and this represents a major challenge recently. To achieve this go...
Performance Investigation of Ethiopian Local Drinking Alcohol Distillation System Using Solar Dish Concentrator.
Publication Type: Academic Journal
Source(s): Journal of Energy (2356-735X). 4/11/2022, Vol. 2022, p1-8. 8p.
Abstract: In Ethiopia, in addition to the large quantity of biomass consumption per year for daily cooking, production of the traditional local "Areke" consumes large amounts of fire wood which further accelerates deforestation. This study introduces solar-based...
Stationary point focus solar concentrators—A review.
Publication Type: Academic Journal
Source(s): International Journal of Energy Research. Apr2022, Vol. 46 Issue 5, p5678-5702. 25p.
Abstract: Summary: The innovation in concentrated solar power (CSP) systems is one of the many vital solutions to meet the ever‐increasing global energy demands. Among various CSP systems, point focus solar concentrators can attain a higher concentration ratio a...

Abstract: • Design and test a new semicircular concentrator with an acceptance angle of 90°. • Use rising film and enhanced condensation techniques to improve still's efficiency. • When mean daily solar radiation is 606.0 W/m2, the water yield efficiency is 81.6...
Novel solar‐powered thermoelectric‐based mobile charger with the capability of operating with different small refractive/reflective concentrators.
Publication Type: Academic Journal
Source(s): International Journal of Energy Research. Feb2022, Vol. 46 Issue 2, p1043-1058. 16p.
Abstract: Summary: The output power of a thermoelectric module (TEM) is not high enough to harvest trivial heat, so it cannot be used to directly harvest solar heat. In this study, a novel method is proposed to utilize a TEM to directly harvest solar energy. The...
Concentrating behavior of elastic fresnel lens solar concentrator in tensile deformation caused zoom.
Publication Type: Academic Journal
Source(s): Renewable Energy: An International Journal. Jun2023, Vol. 209, p471-480. 10p.
Abstract: The focal length of the Fresnel lens changing with the light incident angle will decrease Fresnel lens solar concentrators' energy efficiency and daily working hours, which seriously hinders its commercial application. Existing solutions, mainly includ...
Self‐Tracking Solar Concentrator with Absorption of Diffuse Sunlight.
Publication Type: Academic Journal
Source(s): Advanced Optical Materials. 5/19/2023, Vol. 11 Issue 10, p1-9. 9p.
Abstract: The highest solar cell efficiencies are obtained with concentrating systems. However, these systems have two major drawbacks: solar tracking is needed and diffuse sunlight is poorly absorbed. Here, a system that overcomes both limitations is presented,...
