Thin-film crystalline silicon solar cell can shake the dominance?

Since opening in 2013, Hina Holdings Limited strong expansion, coupled with the crystalline silicon photovoltaic cells continued to slump, the photovoltaic industry was once ignored film photovoltaic cells once again became the focus of the industry. The dispute surrounding the crystalline silicon and thin film planes, the industry formed two diametrically opposed views.
Thin film batteries as a "last straw"
     Thin film batteries as a rising star in continuing to enhance its technical potential is limitless. In the current market conditions, as if the threat to the dominance of crystalline silicon cells.
     On the one hand, after the acquisition of the German company's Q-CELLS thin-film battery manufacturer Solibro, Hina Holding Group realized mass production of thin film solar conversion rate of 14.7%, while thin film solar modules with an annual capacity 3GW, the world's largest thin-film solar business and solar power system integrators. On the other hand, a few days ago the largest CIGS (copper indium gallium selenide) thin-film power plant and power generation, its operators called profit is very considerable.
     In crystalline silicon photovoltaic cell production capacity surplus, prices plummeted, falling profits and experience Europe "double reverse" in the background, thin-film photovoltaic cells has become in the eyes of part of the industry "straw." Han Chairman of the Holding Group Board Jun Li River even said, in the case of crystalline silicon PV products to enter the hardship situation, the only way out is to take a thin film photovoltaic industry line.
      Currently, the industry is mainly respected film photovoltaic from five aspects. First, the development of thin film photovoltaic can effectively solve the trade protectionism. Since last year, the United States and the European Union on China's crystalline silicon photovoltaic products launched the "double reverse" investigation of crystalline silicon photovoltaic products in the European markets cost advantage wiped out, and thin-film photovoltaic products are not in the "double reverse" list.
     Second, thin-film photovoltaic products more suitable for building integration. According to Hina global R & D center, President and CEO Ding said that in a given market, the film has irreplaceable advantages, particularly in terms of building integration. Thin-film photovoltaic cell because it has good flexibility and light transmission characteristics, it can be very easily applied to the outer surface of the building, to facilitate the demolition, to avoid damage to the mounting bracket on the building structure, the same applies to the limited carrying capacity of old construction and light construction.
      Third, compared to crystalline silicon thin film solar PV is more stable, more generating capacity. American Institute chief researcher of the original Sharp, Hunan Science and Technology Co., Ltd. to create a photovoltaic chief scientist Li Tingkai said thin-film battery is suitable for light, low light and scattered light environment, even if the sun is not too strong in the morning, evening or haze weather, too have stable power output. Meanwhile, thin film batteries have a much lower than the temperature coefficient of crystalline silicon cells, the conversion rate of decay with increasing temperature is much lower than the crystalline silicon cells.
Fourth, the thin film PV industry is the solar energy industry China has independent intellectual property rights. In the field of film, have appeared in recent years, domestic Hina Group, Fujian Jun stone with independent intellectual property rights of enterprises have overcome technical bottlenecks low light power generation, reach the world advanced level, from equipment manufacturing, battery production to generate electricity, the entire industrial chain with completely independent intellectual property rights.
Fifth, the thin-film PV costs down fast, affordable Internet access is the first to achieve a strong contender. Does not require the production of thin-film battery slice, refined crystalline silicon ingots, silicon consume less energy, less process chain is short compared to crystalline silicon cells in terms of cost reduction has more space.
View of the above, really informative. Crystalline silicon cells debut earlier, and the technology is relatively mature and stable, high conversion efficiency, it occupies the bulk of the market; thin-film battery as a rising star, and its technology has continued to improve, the potential is limitless. Therefore, under the current crystalline silicon cold market conditions, the film seemed a threat to the dominance of crystalline silicon.
Hard to shake the mainstream crystalline silicon
Crystalline silicon cells have achieved an overwhelming scale production, but also in the conversion efficiency of the core technical indicators still a great advantage, but also in a very long time to occupy the mainstream market.
"Crystal silicon cell efficiency of 0.5 percent per year in accordance with substantially improved its market share accounted for more than 85%." Jia Rui researcher at the Institute of Microelectronics, Chinese Academy of Sciences, said, "Even if 5% of market share year after year attenuation, crystalline silicon cells also able to maintain at least 8 to 12 years, the mainstream position in the market, not to mention has yet to see this happen. "While the traditional process to enhance the efficiency encountered great difficulties, but the new technologies emerging, such as selective emitter plus new backside processing technology, industrial efficiency as high as 19.3%. Jiarui Jiang stressed that although the crystalline silicon cells currently facing a variety of problems, but the development of thin-film batteries will never be easy.
Ding said that the current 15% market share of crystalline silicon cells beyond the basic swept by the thin-film battery, the proportion of silicon-based thin-film battery is about 10%, and the proportion of CIGS thin-film cadmium telluride and other type of battery is approximately 5%. But we know , Hina thin film battery line is silicon thin film battery, the drawback is the low conversion efficiency, short life. Hina go silicon thin film route to nowhere, not to switch to the competition has been fierce crystalline silicon market, you can only choose to update the thin-film technology. Solibro Hina company acquired the world's second-largest CIGS thin film battery manufacturers, although the higher conversion rates, but CIGS itself is still a relatively niche technology, its biggest problem is copper, indium, gallium, selenium four elements together control very difficult, and indium is a rare element. Therefore, even if the prospects for CIGS technology can be compared to already have a mature business model and crystalline silicon cells, a few years later it can become a mainstream technology is hard to say.
Although the long term, thin film batteries is expected to become the future direction of development of photovoltaic cell technology, but crystalline silicon cells have achieved an overwhelming scale production, but it is still much on the efficiency and service life of the core technical specifications advantages, but also in a very long time to occupy the mainstream market. "It is often said the country still have not mastered the key technology of polysilicon, in fact, this is wrong." Jiangsu to deputy general manager Lv Jinbiao said, "From the entire industry to see if there is no breakthrough technology and leading, and not may develop to the current level. "Lv Jinbiao stressed that in difficult times, we must continue to move forward firmly, the potential to play out.
