II. CONCENTRATED SOLAR TECHNOLOGY

Within the realm of concentrated solar technology, this section meticulously examines three prominent technologies: solar concentrators, parabolic troughs, and solar towers. Solar concentrators utilize optical systems to concentrate sunlight onto a small area, intensifying the solar flux. This focused energy is then converted into electricity or used for thermal applications. Parabolic troughs, characterized by curved mirrors, concentrate sunlight onto a receiver tube running along the focal line. The absorbed heat is subsequently utilized for power generation or other thermal processes. Solar towers, on the other hand, employ an array of heliostats to redirect sunlight onto a central receiver atop a tower, where the concentrated heat is harnessed for electricity production [4].

The review elucidates the working principles of each technology, emphasizing their unique attributes and operational intricacies. Additionally, it explores the efficiency gains associated with these concentrated solar technologies, showcasing how they outperform traditional rooftop solar systems. By focusing sunlight and intensifying energy capture, concentrated solar technologies enhance the overall performance of solar power generation, making them particularly relevant in the context of rooftop installations where space constraints necessitate maximizing energy output.

High-efficiency photovoltaic materials form the cornerstone of this exploration, as they hold the potential to significantly enhance the conversion efficiency of solar cells. By leveraging cutting-edge materials with superior light-absorbing and electron-conducting properties, such as perovskite and multi-junction solar cells, the overall energy conversion efficiency can be substantially increased. The utilization of these materials ensures that a higher percentage of incident sunlight is converted into electrical energy, optimizing the overall efficiency of rooftop solar systems [6].

Furthermore, the integration of advanced thermal storage materials addresses the intermittency and variability inherent in solar energy generation. Materials with high thermal conductivity and heat retention capabilities, such as phase-change materials and advanced ceramics, enable efficient storage of excess thermal energy generated during periods of sunlight abundance. This stored energy can then be utilized during periods of low or no sunlight, thereby extending the availability of solar-generated power and enhancing the reliability of rooftop solar systems.

Coatings also play a pivotal role in this integration, serving to protect and optimize the performance of solar components. Anti-reflective coatings minimize energy losses by maximizing light absorption, while hydrophobic coatings can mitigate the impact of dust and environmental factors, reducing maintenance requirements and prolonging the lifespan of solar panels.

The focus of this section is not only on the theoretical aspects of these advanced materials but also on their practical implementation and effectiveness in real-world rooftop solar applications. By critically evaluating their impact on performance, efficiency, and durability, this review aims to provide valuable insights into the tangible benefits and challenges associated with the integration of advanced materials in rooftop solar power generation.
