AWhat changed
Chapin, Fuller and Pearson developed a silicon junction device that converted sunlight into usable electrical power, helping establish practical photovoltaics.
Scientific scope
Chapin, Fuller and Pearson developed a silicon junction device that converted sunlight into usable electrical power, helping establish practical photovoltaics. Scope limitation: The device built on earlier photovoltaic and silicon work, including Russell Ohl. This specific cell is not the first observation of the photovoltaic effect or a measure of current commercial efficiency.
Evidence
Assessment uses the catalogue-linked source evidence for the stated contribution. The device built on earlier photovoltaic and silicon work, including Russell Ohl. This specific cell is not the first observation of the photovoltaic effect or a measure of current commercial efficiency.
