Solar cells through the photoelectric effect or photochemical effects of light energy directly into electrical energy. To work in thin film photovoltaic solar cells for the mainstream, but to work wet photochemical effects of solar cells is still in its infancy.
The term “Photovoltaics” comes from the Greek, meaning light, volts, and electrical, from the name of the Italian physicist Alessandro V, Alexandrov V later in the “V” will be used as voltage units.
History of the development of solar energy, the light shines on the material caused by the “light from electricity” behavior, when in the 19th century has been discovered.
1849 The term “light – V” only appeared in English.
In 1839, the first photovoltaic effect discovered by the French physicist AEBecquerel.
1883 Preparation of a solar cell by the success of Charles Fritts. Charles, covered with a layer of germanium semiconductor thin gold layer of semiconductor metal junction, the device only 1% efficiency.
By the 1930s, the camera’s exposure meter extensive use of light from the principle of power behavior.
Application in 1946 Russell Ohl patented the modern solar cell manufacturing.
To the 1950s, with the gradual understanding of semiconductor properties, and processing technology, the United States in 1954 when Bell Labs found that in the experiment with the silicon semiconductor mixed with a certain amount of impurities is more sensitive to light after the phenomenon The first solar cell was born in 1954 at Bell Labs. The era of solar cell technology has finally arrived.
1960s, the United States launched a satellite to use solar cells have been used as a source of energy.
The 1970s energy crisis, let the world aware of the importance of energy development.
The oil crisis occurred in 1973, people began to move to the application of solar cells in general livelihood purposes.
At present, the United States, Japan and Israel and other countries, have extensive use of solar energy devices, more towards commercial goals.
In these countries, the United States in California in 1983 to build the world’s largest solar power plant, its generating capacity can be as high as 16 megawatts. South Africa, Botswana, Namibia and other countries in southern Africa have set up projects in remote rural areas to encourage installation of low-cost solar power systems.
The implementation of solar power the most active countries devaluation Japan. Japan’s implementation of the 1994 incentive grants to promote the 3,000 watts per “grid connected Solar photovoltaic energy system.” In the first year, 49% government grant funding, and then gradually decline after the grant. “Grid connected Photovoltaic Power Systems” is the time in the sunshine, the solar cells provide electricity to its own loads, if the excess electricity is stored separately. When the power is low or no power when the electricity needed by the power company again.
By 1996, Japan has 2,600 households installation of solar power systems, has installed a total capacity of 8 megawatts. A year later, 9,400 families have been devices, the total installed capacity has reached 32 million watts. In recent years the upsurge of environmental awareness and government grant system, estimates Japan’s demand for residential use of solar cells will rapidly increase.
In China, the solar power industry has also been strong government encouragement and support. March 2009, the Ministry of Finance announced the proposed construction of large-scale photovoltaic solar energy projects to be subsidized.
