In order to improve the conversion efficiency of solar energy, evaluating cavity receivers in Cross Linear Concentrated Solar Power (CL-CSP) systems would thus be very imperative. This study explored several aspects of optical and thermal performance of cavity receivers focusing on challenges during modeling and material degradation during actual operations, considering variable weather patterns. The emphasis of recent technological advancements is on the development of high-temperature materials, advanced alloys and ceramics, and novel selective coatings that enhance optimal absorption of heat with a minimum amount of energy loss through emissivity. Further, hybrid systems-on-chip approach with high thermal storage solutions and sophisticated modeling tools, such as computational fluid dynamics software and ray-tracing software, significantly enhance the overall efficiency of conversion and storage of energies. Experimental validation through controlled testing is important to ensure that these models can realistically simulate the actual behavior of a real system in practice, thus the step between theoretical predictions and practical outcome. The economic and environmental issues are also introduced by the study, citing the expensive initial cost but also how technological and material advances change with time to diminish high costs, improving the economy of the systems. Environmentally, the CL-CSP system is sustainable because it has the capability to reduce greenhouse gas emissions and can operate efficiently under variable solar conditions. As technology advances, CL-CSP systems are going to play a significant role in renewable energy infrastructure expansion that would support the global shift toward sustainable large-scale solar power solutions.
