1、 1 附录 A 英文文献 1.The worlds current situation and development of photovoltaic industry forecast Solar cells is the use of the material effects of photovoltaic solar energy into electrical energy directly to the semiconductor devices, also known as photovoltaic cells. In 1954, the first practical silic

Desert power plant is uninhabited desert area in the development and construction of large-scale photovoltaic power generation systems and networks, the s

In recent years, the rapid increase in solar cell production, for 8 years in 30% growth in 2004, even more than the annual growth rate of 60 percent, reaching 1200MW. 2.The Chinese PV market and industry status 2.1 Chinas solar market development China started
7、 research on solar cells in 1958, in 1971, China successfully launched the first applies to the 2nd satellite Dongfanghong. Started in 1973 for ground-based solar cells. Chinas photovoltaic industry in 80 years ago is still in embryonic form, the annual production of solar cells has been hovering be

As a result of restrictions on prices and production, market development is very slow, and apart from, as the satellite power supply, on the ground only for low-power solar power systems, such as beacon lights, railway signal systems, weather station equipment

In the 65 (1981-1985) and 75 (1986-1990), the countries of photovoltaic PV industry and to give support for the development of the market, the central and local gove

At the same time, 75 period, the domestic has introduced from abroad a number of solar cell production line, in addition to the amorphous silicon, a 1MW battery production line, the other is single crystal silicon cell production line, maki

After the nineties, with the shape of Chinas photovoltaic industry and to lower costs to the industrial application areas and application of the developm

At the same time, grid demonstration project began rapid development, from 5kW, 10kW to 100kW development of more than 1MW Expo in Shenzhen in 2004 and works as a grid PV applications in China highlights. The end of 2004, Chinas total i

Shenzhen, Shantou, Guangzhou and Zhejiang, solar garden lights, a large number of exports, with annual sales of as much as 500 million. Garden of the cells used are usually imported, and then with plastic packaging, simple process

The 6MW cells by as much as a year is a large solar applications (which are not into statistics). 2.2 Chinas status of the industrialization of solar cells Although the rapid development of Chinas photovoltaic industry, the size and technological level of industry have been raised accordingly. But
18、 compared with developed countries, there is still a big gap, such as: the degree of domestic raw materials-specific is not high, species was incomplete, already made materials and components, its performance is lower than abroad, such as silver, aluminum paste, EVA, etc. . Packaging components sued

The upper reaches of small photovoltaic industry chain, the lower reaches of large imbalances, the most serious is that the production of solar grade polysilicon is blank, entirely dependent on imports.

For the commercial development of PV will also be actively support policies and support. 3.1 Rural off-grid photovoltaic power generation plans There are about 28,000 of Chinas villages, 7 1 million, 3,000 million people without electricity. These are the distribution of the population without

These areas withou
27、t electricity have a wealth of solar energy resources, photovoltaic power generation in this region has a vast market prospect. Rural electricity supply problem has been through the power to the villages, the fundamental solution works. There are villages without electricity and household electric power supply issues need to be resolved. If every village without electricity in accordance with the 10KWp, households without electricity in accordance with each 400Wp planning, taking into account the expansion of the power station has been built, the potential market is around 3,000 MWp.
