A review on the applications of porous materials in solar energy systems

According to energy policies, it is necessary to replace electrical energy or fossil fuels by renewable energy sources. Solar energy systems are recognized as one of these sources. In such systems, high-performance is one of the essential needs. Porous materials have been introduced as one of the most efficient and affordable techniques to improve the heat transfer and energy efficiency in solar energy systems. In this review, the applications of porous materials and their advantages and limitations on different types of solar energy systems are summarized. Moreover, the structures of each system with their applications are briefly introduced. Solar energy systems covered in this paper contains both energy conversion and energy storage systems.
