Due to the high cost of photovoltaic power generation, the industry is subsidized by the countries of the world policy-driven. Governments support the introduction of photovoltaic power generation policy, the world’s photovoltaic industry to overcome the international financial crisis, the beginning of warming, coupled with declining investment costs, so that greatly increased the attractiveness of the investment of solar energy. Over the past 10 years regardless of the global PV industry is the production capacity or are over 40% of the compound growth rate of growth in 2008 global production of photovoltaic cells for 6.4GW, an increase of 60%, and continued high growth over the years situation. China has become the world’s largest producer of photovoltaic cells for laptop battery , the production of photovoltaic cells to occupy the global production of around 40%. One of the world in 2008 before the 25 PV enterprises in China accounted for 8, the total output of 1821MW, China Taiwan accounted for three, the total output for the 723.5MW.

From the point of view of the installed capacity in 2008, the world’s installed photovoltaic cells 5600MW, up 134 percent. China’s installed capacity in 2008 is only 40MW, only 0.7%, one can see, the Chinese market for the installation of photovoltaic cells to be activated, the market has great potential.

Chinese version of the solar roof plan ,the domestic photovoltaic industry to help power the coming of spring. Introduced by the end of March the Ministry of Finance “on accelerating the application of solar PV to implement the views of the construction” and so on, in 2009 as a result of subsidies in principle as standard 20 yuan / Wp, PV power generation means that electricity costs can be reduced to 0.58 yuan / kWh, demand for domestic photovoltaic started. We expect that the subsidy program is only the beginning, is expected to launch in May, “the revitalization of New Energy and Industrial Planning,” is expected to further support the introduction of relevant policies.

Thin-film crystalline silicon photovoltaic cells and photovoltaic cells will be growth, compared the cost advantages of more thin-film laptop battery . Crystalline silicon cells cost-per-watt limit for 1.27 U.S. dollars, while the thin-film battery limits cost-per-watt in the following one U.S. dollars. We measured the current installed capacity of silicon cells cost 19 yuan / wp about the cost of thin film solar cells installed in the 12 yuan / wp around. Both are expected to grow, to increase the share of thin-film batteries. The short term the demand for thin-film batteries to focus on areas with low land cost BIPV, and still is the mainstream crystalline silicon, thin-film batteries will increase the share, as the film base of a small battery, and low cost advantages, in its rapid growth, high growth in crystalline silicon cells.

Warmer in accordance with the demand for solar energy industry, all sectors benefit from the different levels of priority, we recommend high-end thin-film laptop battery manufacturers and component suppliers, followed by crystalline silicon cells or the integration of downstream manufacturers, is once again the upper reaches of polysilicon crystalline silicon cells.
