Jacob Rossi PHOTOVOLTAIC POWER CYCLE Conversion of sunlight into electricity via the Photovoltaic Effect Solar Jackets In the most basic form, it’s really similar to normal semiconductor materials: Copper Gold Silver Aluminum Indium Selenium Sulfur Oops: The photovoltaic was accidentally discovered at Bell Labs when impurities were added to Silicon semiconductors. Today’s best photovoltaic cells have a power cycle efficiency of only But, tomorrow’s could approach the theoretical limit of Because of some quantum energy stuff, there exists a “thermodynamic efficiency limit.” Basically, lots of it gets converted into kinetic energy (heat). So don’t worry, it doesn’t break the 1st Law. Even with current technology, the U.S. could become completely independent from oil by building a solar power plant in the Southwest. Its size? 30,000 sq. mi.
