1. Please provide several English literature on solar energy and add a Chinese translation (at least 5000 words in Chinese)

Harnessing the Power of the SunWith rising fuel costs, climate change concerns and a growing demand for electricity, renewable energy resources such as solar power are becoming an increasingly valuable part of the world"s energy mix. Around the globe, businesses and homeowners are harnessing the power of the earth"s most abundant natural resource - sunlight - to provide energy using solar power.GE"s solar electric power systems and products offer high quality, reliable power generation for residential, commercial and industrial applications. By partnering with the sun, solar energy can supply local power for on-and off-grid applications with zero noise pollution and air emissions. Mastering the sun and rising fuel costs, attention to climate change, and increasing demand for electricity, renewable energy resources such as solar power are becoming an increasingly valuable part of the worlds energy structure. Enterprises and homeowners around the world have access to the most abundant natural resource on Earth - sunlight - providing energy for solar power generation. The sun light in the semiconductor pn junction, the formation of a new hole - electron pairs in the pn junction of the role of the electric field, the hole flow from the n area p areas, electronic flow n by p zone area, connected to the circuit after the current form. This is the photoelectric effect of the working principle of solar cells. First, the way solar power generation solar power in two ways, one is light - heat - electricity conversion mode, and the other is light - electric direct conversion approach. (1) light -

heat - electricity conversion of solar radiation through the use of thermal energy generated by power generation, is normally provided by solar collectors to heat absorbed by refrigerant into steam, and steam turbine-driven power generation. A process before it is light - heat conversion process; after a process of heat - electricity conversion process, as with an ordinary power. Drawback of solar thermal power generation is highly inefficient and costly, it is estimated that at least its investment than the average fire Power your 5 to 10 times. a 1000MW of solar thermal power plants need to invest 20 to 25 billion U.S. dollars, an average of 1kW of investment from 2000 to 2500 U.S. dollars. Therefore, at present, can only be applied to small-scale special occasions, and large-scale use in the economy is very uneconomical, but also with ordinary competing power plant or nuclear power plants. (2) Optical - Electric direct conversion approach is the use of the photoelectric effect, solar radiation will be directly converted into electrical energy, light - the basic power conversion is the solar cell device. Solar cell is a kind of volts due to the effects of photovoltaic solar energy will be directly converted into electrical energy device is a semiconductor photodiode, when the sun"s light to the photodiode, the photodiode will be the sun"s light energy into power, resulting in current. When many cells are connected in series or parallel can be up to become a relatively large output power of a square solar cells. Solar cells is a promising new type of power supply, with a permanent, clean and flexibility of the three major advantages. Solar battery life long, as long as there is sun, solar cells can be an investment
