1930 put forward for the first time to use photovoltaic effect to make solar cells and convert solar energy into electric energy.
1932 Audubot and Stora made the first "cadmium sulfide" solar cell.
194 1 year, Odu discovered the photovoltaic effect on silicon.
1954 In May, Bell Laboratories Chapin, Fuller and Pierre released a monocrystalline silicon solar cell with an emission efficiency of 6%, which is the first solar cell with practical value in the world. In the same year, Wake first discovered that nickel arsenide has photovoltaic effect, and deposited a layer of nickel sulfide film on glass to make solar cells, and the practical photovoltaic power generation technology that converts sunlight into electric energy was born and developed.
At the beginning of 20 14, Jinzhai County of our province took the lead in launching photovoltaic power generation poverty alleviation projects in order to implement the new requirements of the provincial party committee for precise poverty alleviation and implement industrial poverty alleviation.
