Solar energy is derived from the sun's radiant energy, which travels to Earth in the form of electromagnetic radiation. This radiation encompasses a wide spectrum, including visible light, infrared radiation, and ultraviolet radiation. Applied physics provides the tools to analyze and understand the characteristics of this radiation, including its intensity, wavelength distribution, and energy content. This knowledge is essential for designing solar energy systems that can effectively capture and convert solar radiation into usable energy.

Solar cells, the heart of photovoltaic systems, are devices that convert sunlight directly into electricity. Applied physics plays a pivotal role in the development of solar cell technology, from understanding the fundamental principles of semiconductor physics to designing and optimizing cell structures. The efficiency of solar cells is directly related to their ability to absorb sunlight and generate electron-hole pairs, a process governed by the principles of quantum mechanics and solid-state physics. Applied physics research has led to the development of various types of solar cells, including silicon-based cells, thin-film cells, and organic solar cells, each with its own advantages and limitations.

Solar thermal energy utilizes the sun's heat to generate electricity or provide hot water. Applied physics is instrumental in designing and optimizing solar thermal systems, including concentrating solar power (CSP) plants and solar water heaters. CSP plants use mirrors to concentrate sunlight onto a receiver, generating high temperatures that drive a heat engine to produce electricity. The design of these systems involves principles of optics, thermodynamics, and heat transfer, all within the realm of applied physics.
