Solar photovoltaic technology related knowledge is introduced

( A) High efficiency low cost solar battery research and development

1. Background

solar energy and other new energy for the world economic outlook in 2000 one of the most decisive influence of the five technical field, and solar photovoltaic power generation is one of the most high-profile projects. In 1994, the world solar energy battery sales volume has reached 64 mw, rapid development present situation. Solar battery sales in China for more than 1. 2 mw. Cumulative dosage of about 5 mw, its application range is also growing. In recent years, the market sales increasing at a rate of 20%, by 2000, the solar battery annual consumption in China will more than 10 mw.

the crystalline silicon solar cell components has been in short supply shortages. To satisfy the increasing market demand, in addition to existing enterprise to play to the existing production potential, and actively develop a variety of high efficiency and low cost of photovoltaic cells, expand the scale of our solar cell industry, improve the technical and economic benefits.

　　2. Target

to improve efficiency, reduce costs, expand the scale, the development of photovoltaic industry development in our country high efficiency and low cost of polycrystalline silicon solar cell technology, research and the combination of introduction, establish YiTiao annual production capacity of production line for megawatt. Improve the efficiency of monocrystalline silicon solar cell components, reduce the production cost, play to the existing production capacity, to meet the market demand.

　　3. Content

1 megawatt polycrystalline silicon solar cell components production line: the establishment of the main technical economic indicators components efficiency 13% life 20 ~ 25 years

2. Monocrystalline silicon solar cell components production line technological transformation of the main technical and economic indicators: component efficiency components of 14 to 15% life 20 ~ 25 years

3. High efficiency and low cost for the development of new type of solar cell.

　　( 2) 。 Solar cell research and demonstration application branch wood

1. Background

solar battery application field in widening in our country, has been involved in agriculture, animal husbandry, forestry, transportation, communication, meteorological, oil pipelines, culture, education and family power, many aspects, such as photovoltaic power generation in remote areas without electricity power supply and many different occasions have remarkable effect on electricity. But look from the overall technology level and scale, the only large gap compared with developed countries, the main problem is the cost of pv systems is on the high side, system supporting engineering equipment without industrialization and application demonstration is not enough and the public the lack of the understanding of the great potential of solar cell application as well as the system application is limited to run independently, have no parallel operation and combined with construction. Therefore, it is necessary to strengthen the solar cell application technology research and demonstration, to promote industrialization, broadening the application fields and market.

　　2. Target

through the project execution, achieve the following goals: small light power industrialization of 100 mw capacity of independent operation of photovoltaic power station under the seriation, standardization, the commercialization of research pattern, photovoltaic power generation technology for large scale preparation

3. Content

(1) small power industrialization of photovoltaic power supply power range: kw, the tile industry scale, the total capacity is greater than 1 mw system cost: than & other; Weaving & throughout; More than 30% lower average price

(2) independent photovoltaic power station operation standardization, standardization and commercialization. Power range: 10 kw to 100 kw system cost: than & other; Weaving & throughout; More than 30% lower average price.

(3) grid photovoltaic power generation technology research and demonstration. Megawatt grid photovoltaic power station in the previous study of 10 kw grid photovoltaic power plant 100 mw demonstration grid photovoltaic power station developed using inverter & throughout; Photovoltaic power station operation and power system related technology research.

4. Young Cheng Guang main technical indicators: the development of the electric pump lift 50 ~ 100 m solar cell power 5 kw ~ 10 kw. 【 The above content of the solar street light for you publish 】
