As the global population and industrialization of developing countries being accelerated, global energy consumption are increasing at a rate of 3% presently, and will keep this growth rate in a long period of time in the future. At present, the world's proven reserves of primary energy are expected to be depleted within 100 years. Therefore, all the countries and regions need to actively develop and utilize renewable energy sources. Because of its cleanliness, health, safety, resource-rich, and many other advantages, solar energy becomes the most important renewable energy sources, and more and more attention are paid to its development.

With the durative decline of PV scale of production and prices, photovoltaic power generation capacity is expected to account for about 20% of all electricity power, becoming one of the basic energy.

However, in the rapid developing PV industry in China, silicon raw materials, and consumer markets are in foreign countries, which will become the latent danger of sustainable development.

Looking forward to the future, Sinotes consultation analysts believe that China PV industry development will show the following trends:

1. Upgading the efficiency and reducing production costs continuously

 Conversion of efficiency and the cost are the two main factors in consideration. For the current silicon solar cells, it is much more difficult to further improve the conversion efficiency. Except exploring new battery materials, the researching focus in the future is centered on how to reduce the cost upward. Existing high-conversion efficiency of solar cells are made of high-quality silicon, which is the most expensive part in manufacturing silicon solar cells. Therefore, how to reduce the cost, while insuring high conversion efficiency, becomes particularly important.

2. Increasing the share of thin-film solar cells

In various types of solar cells, crystalline silicon solar cells still occupy more than 85% of the share. However with the mature of the thin-film solar cell technology, its share will be increased. Polysilicon thin-film photovoltaic cells, organic photovoltaic cells and other membrane can save much valuable silicon materials, and its costs are several times lower than common polysilicon and monocrystalline silicon cells now. Therefore, most industry experts are optimistic about its prospects. each countries consistently invests a great deal of capital in the research and development of thin-film solar cell, and search for the techniques which is low-cost in large scale generation. On the other hand, due to the expansion of PV market size, as the main raw material, high-purity polycrystalline silicon solar cells has small space to reduce costs, and because of technical and financial barriers, expansion program has been greatly restricted.

3. Demand to overcome the bottleneck of raw materials

Facing a broad development prospects, the PV cells manufacturing enterprises are longing for expanding production capacity generally. However, on the one hand the whole industry chain presents a "pyramid" pattern, which cause the expansions of the silicon manufacturers has lagged far behind the battery chip manufacturers; but on the other , to protect their own countries' competitiveness of solar cells, Japan, Germany, Sweden and other countries which export the key raw materials for solar panels have reduced the supply to China, and most of the domestic photovoltaic businesses at the downstream are in a "no rice to cook" position.1000－ton polysilicon launching projects are increasing in various regions at present, 1260-ton-project in Sichuan Xinguang Group，3000-ton-project in SINO-SISINO-SI In Luoyang Province, 1000-ton-project in Chongqing Province, 1000-ton-project in Shizuishan in Ningxia Province, and 1000-ton-project in Linghai Jinhua city in Liaoning Province, etc.

4. The domestic market to start up

China has not been a consumer of photovoltaic products ever. The domestic PV cumulative installed capacity is only tens of megawatts. In 1958, China began to study solar cells, and solar cells were first used in satellite in 1971, and began to use it on the ground in 1973. Due to price control, it slowed down the market development. Solar cells were only used in low-power solar power systems, such as navigation beacon, and railway signal system.

However, in the latest "renewable energy sources and long-term planning", China proposed that: by 2010, China's total capacity of solar photovoltaic power generation will reach 40 million kilowatts, and 220 million kilowatts until 2020, which means that each year the amount of PV power installed capacity will exceed the sum of the past years, and domestic demand will also become very strong. The introduction of the new policy will promote China's solar PV industry, and uplift the development of solar photovoltaic capacity to a new level.
