Do you know the historical origin of photovoltaic power generation?
In 1839, 19-year-old Becquerel, France, experimented with physics and found that the current of two metal electrodes in conductive liquid was increased when illuminated by light, thus the "photovoltaic effect" was discovered. In 1930, he first used "photovoltaic effect" to make solar cells, making solar energy into electricity.
In May 1954, Chapin, Fuller and Pearson of Bell Laboratory in the United States developed a single crystal silicon solar cell with efficiency of 6%. This is the first solar cell with practical value in the world. In the same year, Wick first discovered that nickel arsenide has photovoltaic effect and deposited nickel sulfide film on glass to make a solar cell. The practical photovoltaic technology of transforming sunlight into electricity was born. It happened and developed.
