The global shift towards sustainable energy systems necessitates the effective utilization of renewable energy sources, with solar energy being a pivotal component. This comprehensive review examines two primary solar energy technologies: photovoltaics (PV) and concentrated solar power (CSP). PV technology, which directly converts sunlight into electricity using semiconductor materials, has advanced significantly, particularly with silicon-based cells achieving high efficiencies and cost reductions. Emerging materials such as perovskites promise further efficiency improvements. CSP technology, which concentrates sunlight to generate heat and subsequently electricity, excels in integrating thermal energy storage, providing dispatchable power. Despite higher initial costs and geographical limitations, CSP systems are advancing through innovations in high-temperature working fluids and storage solutions. This paper provides a detailed comparison of PV and CSP technologies, highlighting their respective strengths, challenges, and future directions. The analysis underscores the importance of both technologies in creating a diversified and sustainable energy portfolio, crucial for addressing global energy challenges and reducing greenhouse gas emissions.
