Solar cells convert sunlight into electricity. There are many environmental advantages of solar cells as they use sunlight as a source of fuel and there are no emissions. Solar cells have no moving parts, and electricity is generated noiselessly. They can be installed on the roofs of houses where solar radiation is optimal. Solar cells are still too expensive to compete with conventional forms of electricity production, but the price is expected to fall due to progress in research and increased production.
Research on solar cells at LTH is conducted within the divisions of Energy & Building Design and Building Physics. The division of Energy & Building Design also provides an Internet-based course on solar energy engineering.
