In collaboration with national and international researchers, the head of the department of petroleum engineering in the university of Kerbala “Asst. Prof. Dr. Farhan Lafta” published a new review paper titled “Advancement in Fresnel Lens Technology across Diverse Solar Energy Applications: A Comprehensive Review”. The paper was published in “Energies” which is a Q1 Scopus and Clarivate indexed journal published by MDPI.
The research concentrates on the use of Fresnel lenses in various solar energy systems where solar energy can be concentrated by reflection, refraction or a combination of both. The collectors of a reflection system are designed to concentrate the sun’s rays onto a photovoltaic cell or steam tube. Refractive lenses concentrate light by having it travel through the lens. The sun’s rays are partially reflected and then refracted via a hybrid technique.
The research concluded that the use of Fresnel lenses would significantly increase freshwater production of (L/m2/day) by approximately 467% and significantly increase daily efficiency of (L/m2/day) by approximately 84.7% compared to a typical system without Fresnel lenses. Additionally, using a Fresnel lens to focus sunlight on a very small and fixed area that receives heat leads to achieving significant levels of energy efficiency and relatively low levels of heat loss.
