Photovoltaics

Upon completion of this course, students will be able to:

• analyse and discuss the physical processes that determine the output of different types of solar cells, as well as relate this to the mathematical models that can be used to calculate this output
• explain the mechanism of current and voltage generation in illuminated semiconductors
• describe how solar cells are connected into a module, what the losses are and how these can be minimized
• describe the role, operating principle and performance of the main components of a PV system
• demonstrate understanding of the most common types of electronic power conversion circuits in PV system components
• independently design simple stand-alone, as well as grid-connected, solar electricity systems and choose components for optimal system performance

The course deals with various semiconductor materials and their suitability for solar cell manufacturing, absorption of solar radiation in semiconductors and the principles of solar cells and their physics. Different types of solar cells are studied, their characteristics and how they are assembled in photovoltaic modules. Identification and minimization of losses, degradation, as well as the interpretation and use of the module datasheets as well as manufacturing of photovoltaic modules and the use of photovoltaic modules in both off-grid and grid- connected systems are covered in the course.
During the course, students study different types of batteries, regulators and inverters. The course ends with computer simulations of photovoltaic systems, the design and selection of components.
