Quick Answer
The first practical silicon solar cell was made in 1954 at Bell Labs. It converted sunlight to electricity far more efficiently than earlier designs.
The Full Story
Bell Labs announced the first practical silicon solar cell in 1954. Researchers Daryl Chapin, Calvin Fuller, and Gerald Pearson created a device that could convert sunlight into usable electric power with much better efficiency than earlier selenium cells. While the earliest solar cells were weak, this invention laid the foundation for modern photovoltaic technology. Solar panels are now used from rooftops on Earth to spacecraft in orbit.
