Solar energy technologies have advanced significantly, transforming the way we harness sunlight into electricity. Photovoltaic (PV) systems and concentrated solar power (CSP) are two primary methods that have gained prominence. PV systems convert sunlight directly into electricity using semiconducting materials, while CSP systems use mirrors or lenses to focus sunlight, generating heat that drives turbines. These advancements aim to increase efficiency, reduce costs, and promote sustainable energy production. This review explored the advances in solar energy technologies with emphasis on photovoltaic systems and concentrated solar power. Findings from this study revealed that recent breakthroughs in solar energy technologies have led to improved efficiency and affordability. Perovskite solar cells have shown remarkable efficiency rates above 30%, while tandem solar cells can capture a wider range of sunlight, boosting efficiency. Bifacial solar panels generate energy from both sides, increasing output. Smart solar panels with IoT connectivity optimize energy production and predict maintenance needs. Advancements in energy storage, such as lithium-ion batteries, enable efficient utilization of stored solar energy. These innovations are driving the adoption of solar energy across residential, commercial, and utility-scale projects. Advances in solar energy technologies have transformed the industry, offering improved efficiency, affordability, and sustainability. Innovations in PV systems, CSP, and energy storage have made solar energy a viable option for various applications. As research continues, solar energy is poised to play a crucial role in the global transition to renewable energy.
