According to information, the domestic leading prospective monocrystalline silicon slice of producers phoenix photovoltaic recently completed a new generation of G6 (Generation6) must monocrystalline silicon slice of trial production, and the phoenix photovoltaic plan in June this year INTERSOLAR Germany during the exhibition started a comprehensive promotion.
It is reported, early in February this year, the phoenix photovoltaic finished G6 must monocrystalline silicon chip technology research and development and the applied for patent. And the G5 compared before technology, phoenix pv of this G6 will no longer will have A, B and C district of points (also some manufacturer according to single crystal area divided into L, M, H), but overall area C (single crystal area of 100%), perfect settlement the original polycrystalline mixed single appearance is not the same problem and increase the efficiency of the battery. New technology is to highlight the G6 original transformation to bubble furnace, after the technical output in polysilicon pieces of single crystal area is higher, in the laboratory data close to 100%, and in the process of actual production by more than 95%. Second, G6 technology can sharply reduce the dislocation proliferation, the efficiency is more concentrated distribution, according to the data of battery customers feedback to see, a line of battery manufacturers can make an average of 18.1% and 18.5% of the highest efficiency, make photovoltaic module power can meet the 260 W and maximum 265 W is tolerance. Meanwhile, in the original polycrystalline bubble furnace relative to buy new reform it and save the bubble furnace large cost. New G6 must monocrystalline silicon piece in every piece of cost of polysilicon than traditional not more than 0.5 yuan high, minimum may drop to 0.3 yuan. For the downstream of battery makers and pv modules, the prospective is single monocrystal silicon sheet, the same specification and photovoltaic cells in components can make higher power, and save the photovoltaic module manufacturers in disguised form production process boc pulp, glass, frame of the complementary material such as consumption (for example 1 MW components need 240 W polycrystalline about 4167 piece, and just an offer of 3847 260 W polycrystalline).
Owing to the production capacity of the single crystal is not released in full, the phoenix photovoltaic current priority will be to supply the G6 in Europe and Taiwan customers, also can be in a wholly owned subsidiary of Shanghai phoenix Yang energy science and technology limited company of photovoltaic power station project adopted some must single crystal products. Phoenix photovoltaic plan in the next years, through the continue to work hard to reduce the production cost, and gradually will of all the capacity of polysilicon to prospective monocrystalline silicon slice, to further enhance the enterprise the revenue ability.
Must single crystal technology in nearly a year and a half of time is one of the most industry, at present there are many enterprises have the capacity to produce accurate is single monocrystal silicon sheet, but there has been no rapid development, the main reason is that the high cost, and end customers can’t accept the original G5 technology of off color. At the same time have cost advantage and technical advantage, under the condition of the phoenix pv G6 technology for market acceptance are very confident.
