Since polysilicon prices plummeted after the financial crisis, the original with less silicon consumption, low cost of production can still be a short and long-crystalline silicon thin-film sony vgp-bps8 battery, sony vgp-bpl8 battery industry group into a predicament. Recently, as China’s largest-ever large-scale photovoltaic power plants of 280 MW of concession bidding ended thin film solar project almost “wiped out”, the industry is experiencing an unprecedented crisis.

However, the industry said, thin-film batteries are only short-term bottlenecks encountered the phenomenon of rebirth ushered in the fastest possible next year.

Thin-film batteries have been abandoned

PV companies this year was supposed to be a collective carnival of the year. Strong recovery in the overseas market, from upstream to downstream components of polysilicon photovoltaic manufacturers and other orders than last year’s surge in performance has soared.

But the thin film battery industry is undergoing a series of tests.

As the PV industry representatives, Suntech Power has announced second quarter earnings in the same time announced that it will adjust the company’s development in the next line, to stop the production of amorphous silicon thin-film batteries.

The same battery to lose faith in the film along with Sanyo. The company recently announced suspension of production of thin film solar cell program.

Baoding Yingli Group executives also said in an interview, crystalline silicon still has great room for improvement, while the thin film battery technology is not mature enough, and short life. Therefore, “Yingli Group does not want to film within a decade.”

In addition, some thin-film battery equipment companies dell latitude d630 battery, dell inspiron mini 10 battery in Taiwan have also complained that the orders received since late last year almost to zero.

“As manufacturers of thin film solar cells misgivings about the future, making the expansion pace of stagnation. Most of the film works since late last year to almost any device is no longer under the orders, which also make some equipment manufacturers complain incessantly.” Industry sources said a .

Taiwan thin-film battery plant a person in charge said that as demand and prices for solar cells simultaneously dropped, and it gets squeezed thin film batteries to survive. Thin film batteries last 97% due to reduced use of silicon raw materials is attracting market attention, but since then manufacturers have in the production of polysilicon, silicon raw material prices consecutive “diving” after the cost of polysilicon and thin-film batteries have been far apart, with thin-film batteries high equipment costs, making the film factory investment expansion will be greatly reduced.

However, all of which are smaller than 280 MW of the last round of concession bidding of large photovoltaic power plants to the impact of thin film battery industry. According to this reporter know, thin film battery in the tender of the 13 projects, only one bid because the project consider that the efficiency and reliability of thin-film asus a31-f9 battery, asus a32-f9 batteries on the market and yet the test of time.

Thin film batteries do?

The outside world “misread” thin-film battery?

Reporter learned from the industry, is currently questioned by the parties to the thin film battery mainly in three aspects: first, investment expensive. Industry that, while low-cost amorphous silicon cell material, but with the process of synchronization in the production equipment generated costs, transportation costs, the system cost compared to crystalline silicon cells do not have the obvious advantage. There are even reports that production of amorphous silicon thin film battery components of the device than the crystalline silicon cell module production equipment costs four to five times higher.

Second, the current conversion efficiency of thin film photovoltaic cell is only about 7%, 18% of crystalline silicon cells with a conversion rate is still a considerable gap. Zhengrong Shi, Suntech’s chairman said earlier that the thin film solar cells in the conversion rate of only 6% or 8% of the cases, it is difficult and the crystalline silicon cell competition. The long run, the conversion efficiency of thin film solar cells have to be competitive at 10%.

Finally, the stability of thin-film batteries have also been criticized by the outside world. China Renewable Energy Society, Vice President of Mengxian Gan believes that the current major concern is the business of amorphous silicon thin-film batteries decay. As thin-film batteries instability, 6% -7% of the design conversion rate used in the long process of decay can occur.

But in some thin-film hp pavilion dv6000 battery, hp pavilion dv9000 battery manufacturers, these problems can be solved, some of which only the outside world misreading.

“In fact, thin-film battery devices are relatively expensive. At present the project stopped at the thin-film battery devices that really expensive, since they are all imported from overseas. But as we jointly developed with foreign enterprises that make their own equipment, the cost is much lower . “cell leader in the domestic film directors of Johnson & Johnson Optical Changsha Xiaolin told this reporter that if the introduction of equipment, depreciation expense allocated to more than 0.3 yuan per watt to, and self-built equipment, as long as the depreciation cost of 0.05 yuan per watt.

Previously, Johnson & Johnson’s third-largest optical and vacuum equipment manufacturing companies jointly developed a new thin-film battery technology, core equipment, has achieved the fifth-generation thin-film battery production line in China for the first time in volume production.

As for conversion rates, general manager of the new Austrian photovoltaic home Swank said in an interview, “This is not a conversion rate of over 10% more competitive, but rather in different application fields the question who is more advantageous . ”

He pointed out that thin film batteries in the morning and evening, cloudy and so low-light conditions, can generate electricity, therefore, in the same geographical and meteorological conditions, the annual power generation of crystalline silicon cells higher than 10% -15%. The crystalline silicon cells after the temperature exceeds 50 ℃ will be significantly attenuated. Therefore, in the sunlight strong effect of crystalline silicon cells in areas but poor. The thin film cells only a weak attenuation toshiba pa3476u-1brs battery, toshiba pa3399u-1brs battery at high temperature, especially suitable for high temperature, desert construction of power stations.

For the stability problem, Sha Xiaolin told reporters cited four examples to illustrate the stability of thin-film battery is not bad. First, the amorphous thin film battery from successfully developed over 50 years now, after a long test; Secondly, a thin film of California’s electricity power station 18 consecutive years, is still in power generation; Third, UL, Europe TUV amorphous thin-film batteries have been on the simulation test, the test environment is a continuous 85 days in the high and low temperature conversion box withstand hot and cold, the results prove that stability can be achieved 20 years of power generation; Finally, the German insurance group Munich Re has insured our thin film batteries 20 years, this is also the argument by the insurance company.

Welcome turning point next year or

Despite the recent suffered a setback, but in many of the industry view, once the breakthrough technologies of the future, or further increases in the price of polysilicon, thin film battery is still great potential, “An example is the world’s largest solar energy company is a pure FirstSolar thin film battery business, they rely on the cadmium telluride is a unique technology. ”

Ministry of Industry and Information Technology Wang Bo, deputy inspector of electronic information had previously said publicly that the current domestic battery business more than 60 films, although the proportion is still high, but as a representative of the new technology, the energy conversion efficiency is gradually increased, production costs also reduced the proportion expected in the future will be increasingly high, and the next play to its own advantage.

“Although the price of the product hp 500 battery, hp 520 battery with the decline in crystalline silicon, thin film cells differentiated competitive advantage has been weakened, but the company is still devoted much of its energy, and is gradually enhance their competitiveness.” Zhejiang Chint Solar Energy Technology Co., Ltd. General Manager YANGLI the reporter said.

Baoding Tianwei Ma, general manager of thin film photovoltaic literature also quite confident that the future of thin-film battery, “the relevant thin-film battery technology is still in its infancy, is much room for technological advances, the cost can fall, we should be on the emerging products to give sufficient confidence. ”

“Thin-film batteries is likely to usher in the next inflection point.” Sha Xiaolin pointed out that polysilicon prices began to steadily rise, making the cost advantage of thin-film batteries again starting to show. On the other hand, countries to reduce subsidies for solar installation is the trend, while the decline means that the cost pressures to increase subsidies, which impact on the crystalline silicon cells is much greater than the thin film battery, “the lower the subsidy, the better thin-film batteries.”

According to him, the amorphous silicon thin film battery construction of the lowest cost power plants can do 1200-1300 yuan / MW, while the crystalline silicon cells in order to build power plants, is still difficult to achieve the cost line.
