11-Sunlight can be converted directly into electrical output by photovoltaic cells. These cells have been used for auxiliary power generation in spaceflight applications as well as for terrestrial applications in remote areas. Investigate the principle of operation of photovoltaic cells for electric power generation. What efficiencies are achieved by present designs, and how are the efficiencies defined? What is the potential for more widespread use of this technology? Summarize your findings in a memorandum.
