Struggles over the direction of the solar energy industry

The Hina Group Chairman Li River Jun, said at the meeting, saying do not agree with the photovoltaic industry overcapacity, large-scale solar energy applications, an alternative to traditional energy era has arrived.

Crystalline silicon cells and thin-film solar photovoltaic power two different routes, has been engaged in the contest of the cost of the conversion rate. Previously, the outside world had questioned the high cost of Hina thin film solar technology applications, the conversion rate is low here Li River monarch responded and gave a negative.

According to previous media reports, the thin-film solar components once costs are slightly lower, but Suntech, Yingli and other Chinese companies expansion can crystalline silicon PV module prices lower, if single calculation of the cost of photovoltaic power plant equipment, solar panel thin-film modules prices are now higher than the crystalline silicon PV modules to more than 20%, coupled with the use of solar thin-film modules require a larger area to absorb solar energy, thus increasing the cost of land, the system operator costs higher. Do the same solar film First Solar is the world's largest manufacturers of PV modules, is now in decline.

Many people think that the high cost of thin film solar kWh, that five years ago, and is now comparable to crystalline silicon solar Li River Jun said. Hina thin-film photovoltaic technology has reached the international advanced level the conversion rate, which reached 15.5% conversion rate of copper indium gallium selenide (CIGS) components production.

River Jun Lee further said that the cost of power generation of thin film batteries, there is a great decline in space, because the theory of thin film battery conversion rate is 30%, than the crystalline silicon cells with high conversion rate, conversion rate of the latter theory is only 29%.

Talking about the difference between the two, Li River Jun, crystalline silicon cells is the generation of products, thin film battery is a second-generation, three generations of products, and the former is equivalent to a black and white TV, which is equivalent to the LCD TV. In his view, the production of thin-film batteries no pollution, high energy consumption should become the mainstream in the development of solar energy industry, crystalline silicon solar thin film solar difficult to replace.

"PV crystalline silicon and thin-film two techniques, film, flexibility is the overall trend of the development of the World Solar" Li River monarch analysis. Domestic photovoltaic enterprises choose film route is not much, is mainly limited by the size and core technology. Film is not like crystalline silicon, is not simply the purchase of equipment that can be produced, but need ongoing technical research and development and capital investment at the same time to do, such as First Solar (First Solar) as more than 2GW capacity scale, will it be possible to reduce the cost .

He said, Hina has always attached great importance to the research and development of thin-film solar cell technology and inputs, through independent innovation and technology mergers and acquisitions, has seven thin-film amorphous silicon germanium and nanocrystalline silicon and copper indium gallium selenide solar products technology. In June this year, Hina acquired German solar giant Q-Cells, a wholly owned subsidiary Solibro, its film production conversion rate of over 15%, the world leader.

Public information, Hina was founded in 1994, is headquartered in Beijing and currently employs more than 5,000 people. Has branches in several provinces of the domestic as well as North America, Europe, Asia-Pacific and other regions, and is today the largest and highest degree of specialization across hydropower, wind power, photovoltaic power generation private clean energy companies. At present, the total installed capacity of more than Hina hydropower project interests 6GW (600 megawatts), the total installed capacity of 131MW of wind power (13.1 kW), while the PV total capacity reached 3GW (300 megawatts), has become the world's largest thin-film photovoltaic enterprises.

Since 2009 to enter the thin film solar cell industry, which has so far invested in Heyuan, Guangdong, Sichuan Shuangliu, Haikou, Hainan, Shandong Yucheng, Changxing, Zhejiang, Jiangsu Wujin other places to build thin-film solar R & D and manufacturing base, a total investment of about 27 billion yuan .

About photovoltaic industry overcapacity saying Li River Jun, global PV application market is still an annual rate of nearly 30% in the growth, at the same time, the market is not exactly the same film and crystalline silicon film market is not only there is no surplus, but is just the beginning.
