“Thin film photovoltaic is the development direction of the photovoltaic industry in the future. In the future, the development speed of thin film photovoltaic will exceed expectations.” At the inaugural meeting of China Thin Film PV Industry Alliance held recently, Vice Chairman of the All-China Federation of Industry and Commerce, National Energy Federation of New Energy Li Hejun, president of the Chamber of Commerce, was elected chairman of the alliance. He said that in the next 3-5 years, film will become the mainstream of China's photovoltaic industry.

Industry alliance

The "Twelfth Five-Year Plan for Photovoltaic Industry" proposes to focus on the development of laminated and multi-junction thin-film batteries combining amorphous and microcrystalline, making thin-film solar cells a priority for the development of the photovoltaic industry. The 18th National Congress of the Communist Party of China clearly proposed to take the road of new urbanization development. Under the policy orientation of new urbanization construction, the thin film photovoltaic industry will show greater development opportunities in distributed generation. However, just like all strategic emerging industries in the development and growth, the current thin film photovoltaic industry system is still not perfect, and there are still many tasks to be accelerated in application promotion, and the state needs to be supported by policies.

"In this situation, it is urgent to set up an organization as a bridge and link between the relevant state agencies and enterprises, enterprises and enterprises to communicate and cooperate with each other, supplemented by information services, promote industry self-discipline, regulate market order, and promote solar thin film photovoltaic The healthy and orderly development of the industry." Li Hejun said that the thin film photovoltaic industry alliance came into being under the strong appeal of the majority of thin film photovoltaic companies, in line with the direction of industrial development, but also led many thin film photovoltaic companies to participate in the international market competition and seize the global film. The heavy responsibility of the commanding heights of the photovoltaic industry.

It is understood that the China Thin Film Photovoltaic Industry Alliance is led by Hanergy Holding Group, and is jointly initiated by more than 100 thin-film photovoltaic companies and research institutes such as Dongyue Group, Henderson Weiye, Platinum Sunshine, Dongdian Kechuang and Amarton. Promote the sustainable and healthy development of China's solar energy and new energy industries.

“The establishment of China Thin Film Photovoltaic Industry Alliance marks the official establishment of the nation's first thin-film photovoltaic industry organization, carrying an important responsibility to lead the healthy development of China's solar energy industry, and will have a profound impact on the development of global new energy industry.” People said that the establishment of the alliance will inject new vitality into the development of China's thin film photovoltaic industry, leading the photovoltaic enterprises into the "film era."

Opportunities and challenges coexist

Controlling and reducing the total consumption of fossil energy and increasing the proportion of clean energy use are inevitable requirements for building a beautiful China. It is also the goal of optimizing the energy structure and building a safe, stable, economic and clean modern energy industry system. According to the plan of the Air Pollution Prevention Action Plan, by 2017, the proportion of non-fossil energy consumption will increase to 13%. The "Twelfth Five-Year Plan for Energy Development" promulgated by the State Council proposes that by 2015, the proportion of non-fossil energy consumption will increase to 11.4%, and the proportion of non-fossil energy power generation capacity will reach 30%.

"From the current point of view, the development opportunities and challenges of the thin-film photovoltaic industry coexist." Li Hejun said that the Third Plenary Session of the 18th CPC Central Committee mentioned the ecological civilization construction to an unprecedented height, and proposed a number of markets related to ecological compensation and paid resources. The reforms require that environmental problems such as smog become increasingly severe, and the development of new energy sources, especially clean solar energy, is urgently needed. The state is also actively exploring and introducing relevant industrial policies to promote the healthy development of the photovoltaic industry and increase financial support for the photovoltaic industry. This provides an opportunity for the development of the thin film photovoltaic industry.

It is understood that photovoltaic is divided into two technical routes of crystalline silicon and thin film. The advantage of crystalline silicon solar cell is that the conversion rate is relatively high. The disadvantage is that the production process is polluted. It is only suitable for high light environment and cannot generate electricity under weak light. With the advantages of low cost, flexibility, light weight, etc., it can be widely used in photovoltaic building integration, and flexible film components can also be applied in emerging applications with high added value. At present, in the global photovoltaic market, crystalline silicon accounts for 85% of the market, and thin film photovoltaic cells only account for 15%.

According to Wang Wenjing, director of the Solar Cell Technology Research Office of the Institute of Electrical Engineering, Chinese Academy of Sciences, thin-film photovoltaic cells have experienced two rapid developments, one in the late 1980s, when thin-film photovoltaic cells accounted for nearly 30% of the total photovoltaic cells. Another time was during the surge in polysilicon prices in 2008, when thin-film photovoltaic cells accounted for nearly 20% of the total photovoltaic cells. But since then, with the decline in polysilicon prices, the proportion of thin film photovoltaic cells in the entire photovoltaic cell has dropped to the current 10%-11%.

“There are not many PV companies that choose the film route in China. The main reason is that they are subject to scale and core technology. Because the film is different from crystalline silicon, it can be produced simply by purchasing equipment, but requires continuous technical research and development and capital investment. It is possible to reduce costs by achieving a larger scale of production capacity. The thin-film photovoltaic industry is currently in the early stage of development, and the government should introduce relevant support policies to support it,” an industry source said.

"How to develop the photovoltaic industry is indeed a very important issue before us. From a macro perspective, solar energy is optimistic both at home and abroad, but from now on, the development of the domestic solar industry faces many challenges. New energy companies I hope that the government can give more policy support and give more financial subsidies." Zhang Guobao, director of the National Energy Commission's expert advisory committee and honorary chairman of the China Thin Film Photovoltaic Industry Alliance, said that if an industry only expects state subsidies to develop, it must be done. Not up.

"Photovoltaic and even the development of new energy industry can not rely solely on government subsidies. The fundamental way out for future industrial upgrading is to reduce the cost of enterprises by improving their own competitiveness. First, thin-film photovoltaic enterprises should increase investment in scientific research to further reduce solar modules and solar energy. The cost of the battery; secondly, it is necessary to make the cake bigger, only to grow up to dilute the cost." Zhang Guobao said.

"The new energy price difference is subsidized by the new energy fund. At present, the new energy fund of 60 billion yuan in the country. If the scale of industrial development in the future expands, the financial subsidies will not keep up, and the development of the industry will be limited. It is impossible to form how many subsidies are used. Li Hejun believes that thin film photovoltaic is the development direction of the photovoltaic industry in the future, and is expected to become the mainstream in the next 3-5 years. At present, thin-film photovoltaics account for only about 15% of PV module manufacturing. Since the conversion rate of thin-film photovoltaic modules is 5%-15% lower than that of polysilicon, the on-grid price is relatively expensive and the degree of industrialization is slightly lower. A number of participants said that with the guidance and assistance of the alliance, thin-film photovoltaic enterprises will strengthen management and achieve technological innovation, further reduce costs and promote the industrialization of thin-film photovoltaics.

Thin film photovoltaic is the future development trend

The National Energy Administration recently stated that the scale of China's distributed photovoltaic construction in 2014 was 8 GW, which will bring development opportunities for the thin-film photovoltaic industry with unique advantages in distributed projects such as photovoltaic building integration and photovoltaic agricultural greenhouses.

“The best carrier for PV application in urban areas is architecture. Building is the main source of photovoltaic energy use and carrier.” Zhong Jishou, director of the National Residential and Residential Environment Engineering Technology Research Center, said that thin film photovoltaics can use glass as a substrate or Stainless steel is used as a substrate and can also be used on flexible coils, such as integrated with building materials to replace certain materials. Therefore, in addition to the price of photovoltaic itself, other factors will not increase the cost of the building. In addition, in photovoltaic applications, the roof and wall of the building can be fully utilized for installation, which can effectively save land.

“Thinning and flexibility are the general trends and directions of global solar energy development.” Li Hejun said that the flexible and lightweight characteristics of thin-film batteries make it a broad application market, such as photovoltaic building integration, rooftop power stations, ground power stations, application products, etc. . Applications include solar emergency lights, street lights, camping kits, chargers, and the solar car market.

It is understood that the integration of photovoltaic building refers to the transformation of various buildings into photovoltaic power stations, the establishment of a "spontaneous use, redundant Internet access" distributed power system, making energy use more convenient and more economical. It is estimated that China's available urban and rural construction area is close to 90 billion square meters, with an installed capacity of about 1,000 GW. Only photovoltaic building integration can form a market cake of 30 trillion yuan. Experts believe that flexible, low-light response, efficiency improvement, potential, and easy integration with buildings are the unique advantages of thin-film photovoltaic cells. In the future, thin films will have a huge market development space in the integration of photovoltaic buildings.

"You can compare film and crystalline silicon to the relationship between desktop computers and iPads and iPhones. Desktop computers are always in use, but iPads and iPhones are the mainstream of the future. Now the film is a minority, and it must be the majority in the future." Li Hejun believes that thin film photovoltaic It will be the future development trend.
