- Previous attempts at solar cells (using selenium) had an efficiency of less than 1%. This silicon cell achieved an efficiency of 6%, a massive breakthrough.
- During the public announcement on April 25, 1954, Bell Labs demonstrated the technology by using the solar panel to power a small mechanical toy Ferris wheel.
- The technology was quickly adopted by the space program; the Vanguard 1 satellite (launched in 1958) was the first artificial earth satellite powered by solar cells.
