pb225 - Renewable Energies I (Complete module description)

Präsenzzeit: 56 Stunden Selbststudium: 124 Stunden

Introduction to physical principles and application of renewable energies, with special emphasis on energy conversion, utilization and planning. The student will be able to understand the funda-mental principles of renewable energy technologies. In either the field of wind energy or photovoltaics the student will be able to determine the natural resources, to analyse the physical principles and to design a basic energy converter/power plant. In addition, the student will be able to assess the economics and ecological effects.

Introduction to Renewable Energies: Energy supply and demand; energy use & climate change, energy resources; renewable energy sources (resources, technology & application): photovoltaics, solar thermal systems and power plants, wind power, hydropower, geothermal energy, biomass; hydrogen technology and fuel cells; energy storage; sustainable energy supply. Wind Energy Utilization: history and prospects, wind resources, typology and function of wind energy converters, aerodynamic design, basic characteristics and power control, mechanical and electrical design of wind tur-bines for grid connection or stand-alone, loads and dynamics, wind farms, offshore wind power, economics, ecological and political aspects. Photovoltaics: Introduction to solar cells, properties of sunlight, p-n junction physics, operation of solar cells, cell characterization (I-V curve under dark and illumination, conditions, cell efficiency, fill factor, short-circuit current, open-circuit voltage), PV technologies (single crystalline Si cells, micro-, poly-, and multi-crystalline Si cells, amorphous Si cells, III-V multijunction cells, concentrator PV, CIGS solar cells, CdTe solar cells, Dye-sensitized solar cells, organic solar cells), nanotechnology and solar cells, module manufacturing, PV economics.
