Solar power history
Since 1954, the first practical photovoltaic cells, solar photovoltaic power generation has made considerable progress. But the development of computer and optical fiber communication more slowly. The reason may be the pursuit of information is particularly strong, and conventional energy can meet the demand for energy. The environmental pollution problem of the oil crisis of 1973 and 90, greatly promoted the development of solar photovoltaic power generation. The development process of Jane as follows:
In 1839 the French scientist Becquerel discovered the "photovoltaic effect", namely "photovoltaic effect".
In 1876, Adams discovered the photovoltaic effect in solid metal and selenium.
In 1883 produced the first "selenium cell", used as a sensitive device.
In 1930 Schottky proposed the Cu2O barrier "photovoltaic effect" theory. The same year, Langer was first proposed by the "photovoltaic effect" manufacturing "solar", the solar energy into electrical energy.
In 1931 Bruno will compound of copper and selenium silver electrode immersed in electrolyte, in the sun to start a motor.
In 1932 Audu Bott and Stora made the first "CDs" solar cell.
In 1941, Orr discovered the photovoltaic effect in silicon.
In the United States in 1954 Qiabin and Pilson Baer laboratory, first made of single crystal solar battery of the utility, efficiency is 6%. The same year, Wei Kerr first found the GaAs photovoltaic effect, and the deposition of cadmium sulfide thin films on the glass, the first piece of thin film solar cell.
The photoelectric conversion efficiency optimization design in 1955, when Ginny and base material. The same year, the first appearance of photoelectric navigation light. The United States of America RCA research of GaAs solar cell.
In 1957 the silicon solar cell efficiency up to 8%.
In 1958 the solar cell for the first time in space applications, the United States of America the vanguard 1 satellite power supply equipment.
In 1959 the first polycrystalline silicon solar cell, efficiency is up to 5%.
In 1960 the first realization of parallel operation of silicon solar cell.
The photoelectric conversion efficiency of up to 13% 1962 of GaAs solar cell.
The 1969 film CDs solar cell efficiency up to 8%.
In 1972, when base developed violet photocell, efficiency is up to 16%.
In 1972, America Astronautics Co BSF cell appearance.
In 1973 the GaAs solar cell efficiency up to 15%.
In 1974 COMSAT proposed no reflection textured cell, the silicon solar cell efficiency up to 18%.
In 1975 the amorphous silicon solar cell appearance. The same year, with silicon cell efficiency up to 6%~%.
In 1976, polycrystalline silicon solar cell efficiency up to 10%.
In 1978 the United States built 100kWp solar photovoltaic power station.
Monocrystalline silicon solar cell efficiency in 1980 reached 20%, GaAs cells reached 22.5%, up to 14.5% of polycrystalline silicon cells, CDs cells reached 9.15%.
In 1983 the United States built 1MWp photovoltaic power station; metallurgical silicon cell efficiency up to 11.8% (extension).
In 1986 the United States built 6.5MWp photovoltaic power station.
In 1990 Germany put forward "2000 photovoltaic roof plans", each family roof installed photovoltaic cell 3~5kWp.
High efficiency in 1995 reached 32% spot of GaAs solar cell.
In 1997 the United States put forward the "President Clinton million solar roofs plan", before 2010 1000000 households, each household to install 3~5kWp. Photovoltaic cells. The sun times volts to the roof of the power supply, meter inversion; without sun grid to power homes, the meter is turned. The family only "net electricity".
In 1997 the Japanese "new sunshine plan" proposed that by 2010 the production of 4300000000 Wp photovoltaic cells.
In 1997 the European Union plans to 2010 production of 3700000000 Wp photovoltaic cells.
The efficiency of crystalline silicon PV cells reached 25% in 1998. The Holland government proposed "the Holland million solar roofs plan", to be completed in 2020.
