200 B.C. Archimedes ,Legend holds that Archimedes, a Greek scientist, used a series of mirrors on the shoreline to concentrate the sun’s energy and set fire to incoming enemy ships.
1839 ,Photovoltaic Effect,A.E. Becquerel observed that shining light on certain materials would cause the creation of electric current. This was the launching point for photovoltaic technology.
1883,1st Solar Cell,Charles Fritts produces the world’s first solar cell, a device that converts sunlight into electricity, using selenium and gold. The cell’s efficiency was less than 1%, meaning than less than 1% of the light energy was converted into electricity.
1921,Photons,Albert Einstein is awarded the Nobel Prize in Physics for his “discovery of the law of the photoelectric effect.” Einstein was the first to postulate the existence of light quanta, now called photons, providing a theoretical foundation for modern PV technology.
1954,Commercial Solar,Silicon solar cells make their way into the mainstream market. The New York Times noted that the silicon cell could lead to “the harnessing of the almost limitless energy of the sun for the uses of civilization."
1958,Space Race,The space race between the U.S. and Russia sparks significant investments in solar technology. Some of the earliest man-made satellites, including Vanguard 1, were powered by photovoltaic cells.
1985,20% Efficient Cells,A silicon solar cell breaks the 20% efficiency barrier. High-efficiency, low-cost silicon solar cells make their way into commercial production.
1960,silicon solar cells were connected to the grid for the first time
1978, the U.S. built a 100 kw photovoltaics
1983, the United States referred to 1MW photovoltaic power station
1986,6.5 MW photovoltaic power station
1990, Germany proposed the Solar 2000 solar roof project, each household roof installation 3-5 kw solar power station
1997, the United States offered President Clinton a visit to the solar rooftop project, and Japan's 4.3 gigawatt solar project
1998, the Dutch government proposed a million photovoltaic rooftop project
1999, Japan surpassed the United States for the first time in total solar cell production
2006,The Silicon Rush,Solar industry surpasses the computer industry as the largest consumer of high-purity silicon. Although this created a temporary silicon supply shortage, it sparked major industry investments that lowered the price of solar panels.
2010,EU plans to produce 6 GIGAWATTS OF PHOTOVOLTAIC CELLS
