Basic physics of semiconductors : Solar Energy

This course on Basic Physics of Semiconductors: Solar Energy provides a foundational understanding of how semiconductor materials enable the conversion of sunlight into electrical energy. It begins with core concepts such as atomic structure, energy bands, charge carriers, and intrinsic and extrinsic semiconductors. Participants will explore the behavior of electrons and holes, carrier generation, recombination, and transport mechanisms in semiconductor materials. The course then connects these principles to photovoltaic (PV) technology, explaining how p-n junctions form the basis of solar cells.Learners will gain insights into the working principles of solar cells, including light absorption, electron excitation, and current generation. Key performance parameters such as efficiency, fill factor, and open-circuit voltage will also be discussed. The course further introduces different types of solar cells, including silicon-based and emerging technologies. Practical aspects such as material selection, losses, and device optimization will be covered to bridge theory with real-world applications. By the end of the course, participants will have a clear understanding of semiconductor physics and its critical role in solar energy systems.
