The document discusses the application of solar cells. It begins by outlining the objectives of understanding the principles of solar cells, their common usage among undergraduates, benefits and drawbacks, and future development. It then provides details on how solar cells work, their applications in households, vehicles, space technology and battery charging. The document reports the results of surveys on student usage and perceptions of solar cells. It finds most students recognize the environmental and cost benefits but have room to improve their understanding of technical aspects. It concludes solar cells provide a renewable and pollution-free alternative to fossil fuels that will become more prevalent as efficiency and affordability increase over time.
