The course is aimed to provide a theoretical background of the photovoltaic solar energy conversion. It is focused not only on the classical crystalline silicon cells but it follows also modern trends in exploiting new materials, including polymers, and new physical principles. The students will learn mathematical and theoretical background of the photovoltaic effect in various functional structures and materials. The part of the course will be dedicated to the practical and economical aspects of the application of solar cells in the distribution power networks. The life cycle assessment will provide students with better understanding of the relation between the photovoltaic cells application and environmental protection.


Knowledge of theory of solid states and semiconductors physics ( lectures 11TPL, 11POL1 at FNSPE)
