China thin film solar cells will be the “world factory”

Oerlikon as the world’s first thin-film solar modules to provide Turn-Key service vendors, and its thin film solar modules using amorphous silicon technology solutions and microcrystalline silicon thin film technology stack to provide include conducting glass (TOC) production, PECVD deposition , laser cutting and other critical thin-film battery manufacturing process steps. Oerlikon Solar Division, Sun Haiyan, general manager of technical marketing in Asia that China has relatively abundant raw materials (glass) market and talent pool, China thin film solar cells will become the “world factory.”

SIChina: Do you think Chinese enterprises to enter the thin film solar PV market, where the starting point?

IRRIGATION: We first from the perspective of industry chain to talk about why should thin film solar cells: First, the thin-film solar has a cost advantage; Second, the thermal expansion coefficient of less widely used. Again, China has the advantage into the thin-film solar industry. Because the cost of thin film solar cell structure, raw material in glass accounts for about 40%, while domestic glass production is the largest, relatively low raw material prices. At the same time the country has rich reserves of talent, these people including those from the semiconductor, FPD and electronic industries. With the semiconductor and flat panel display industry, compared to thin film solar cell equipment and capital requirements, technology, lower than the threshold value, if our goal is 0.7 dollars per watt, then the middle position must have a dessert, the key to see how you do.

SIChina:: able to analyze the trend of thin film solar cell technology?

IRRIGATION: thin-film batteries have a 30-year history, limited by the conversion efficiency, in the past did not form large-scale production of thin film batteries to open the market. The past two-junction amorphous silicon thin film solar cell conversion efficiency is only about 5%, there are also problems with packaging technology, and thus the cost advantage of thin-film batteries can not be displayed. Current industry began to enter the thin film solar cell mass production. Oerlikon began in 2002 to devote additional microcrystalline amorphous project, the use of this process, after the initial decay can be expected after the conversion efficiency of 10% or more, at present, we can ensure that customers achieve the conversion efficiency of 9.3%. Through equipment upgrades, you can upgrade process technology from the amorphous to microcrystalline amorphous plus technology. The future of thin film solar cells bottleneck is: First, how to improve the conversion efficiency; the second is how to improve its manufacturing efficiency, Oerlikon and customers can build database, for the equipment company in terms of lower TackTime time is critical, that is reduce the manufacture of each piece modules of the time; The third is to form a scale, through the overall control, to achieve cost-effectiveness.

SIChina:: As the world’s first thin-film solar modules to provide Turn-Key service vendors, you think this pattern of Turn-Key will give the battery on the domestic film industry, what impact the development? As producers of technology depends on the equipment suppliers, will result in customer product no difference?

IRRIGATION: The current process is mainly dependent on thin film solar cell equipment supplier. The technology developed by Oerlikon laboratory, pilot production line and then, we recommend the entire line of large customers to buy product also bought the pilot line of 1:1. 1; 1 pilot online customers increased efficiency in the conversion there are a lot of space. Can be 1; 1 in a pilot process successfully transplanted directly to the menu production line. Thin film battery has just started a large-scale industrialization, it is not yet time to consider product differentiation, each solution has the market for Oerlickon, we seek not a big size, and above all the maturity of the production line. An important sign is by TUV and other international certification. Oerlikon’s amorphous silicon modules has been TUV certified in 2006, most recently through the use of their TCO, TUV certification process production modules, which can make the products to customers quickly enter the market. Besides the high conversion efficiency is the goal we seek. The maturity of the existing platform can be upgraded to increase the conversion efficiency of the battery. Process to increase from the amorphous microcrystalline amorphous process, possible future increase in the amorphous and microcrystalline an intermediate layer between the increase in the degree of light absorption in order to improve transformation efficiency, the production line can continue to upgrade with the upgrade process, it has the equipment can be subsequently upgraded, so the production line efficiency, cost reduction.

SIChina: Do you think thin film solar cells with silicon-based solar cells when it comes time rival?

IRRIGATION: We estimate the global solar PV market will grow from $ 1,000,000,000 in 2000 to expand by 2015 to 1500 billion U.S. dollars, while the thin film market share may be increased from 2% to 52%, beyond the crystalline silicon solar cells, into the mainstream.

Solar cells “hiding” the glass change materials

Reporter November 24 public cultural center in Weihai on construction sites to see, Optoelectronics Co., Ltd. Weihai several staff being on-site measurements of solar roof “glass cell” installation has entered the implementation stage. It is reported that members of the public cultural center of the roof of Weihai total area of 6,000 square meters, all with embedded thin film solar glass, is the world’s largest amorphous silicon photovoltaic roof project (ie, solar glass, batteries), the project also broke the solar “glass cell” is all the conventional plane, is the world’s first solar energy to wave-shaped design of the “glass cell” roof.

In order to promote use of renewable energy, Weihai cultural center in the design of the public, decided to 6,000 square meters of roof used in all BIPV (building integrated photovoltaic) mode building, that the entire roof is a huge solar “glass cell” . Traditional solar cells are laid over the existing roof, and this project requires the direct use of solar energy “glass cell” to do the roof, building materials, but also to the wave-shaped design, construction difficult. Weihai City in October this year, the General Assembly has held a tender, the world within six companies to participate in bidding, Weihai lowest BID.

It is reported that in use the world’s largest amorphous silicon photovoltaic roof project is a New York subway station Stillwell 210 kW amorphous silicon photovoltaic roof. “The Stillwell subway station is open style, for the roof insulation performance no special requirements. In addition to our large area of the project, unique addition to the building because the roof is closed, the ‘glass cell’ of the thermal insulation performance requirements for high This made our products a higher demand. “Weihai Xin, General Manager, Industry said.

Use of solar power generation does not use any chemical fuel, emissions of harmful substances into the environment will not, and no moving parts and no noise, is a real renewable energy in the clean green energy. It is understood that, coupled with lighting district, Weihai public cultural center area of the photovoltaic power generation system of more than 7800 square meters, DC-rated power 273 kilowatts, the annual power generation of about 330,000 kwh. 118 tons of standard coal can be saved annually, 327 tons of carbon dioxide emissions, 9.8 tons of sulfur dioxide emissions, 780 kg of nitrogen oxides emission reduction has become a veritable “green building.” It is estimated that electricity generated by the system can meet the cultural center of the public part of the office lighting needs and use of electricity, roofing works will be completed next January, the entire project will be put into operation late next year.
