City accounted for more than 50%? SE technology application prospect is considerable

Solar photovoltaic (pv) net news: in the development of photovoltaic cell technology route, the efficiency is an eternal theme. The P type single polycrystalline PERC cell technology has become the mainstream of the market, and selective emitter technology ( 我发射器,SE) Because of its conversion efficiency, compatible with cell line strong advantages, more to the development of the PERC cell rise space.

recently, chint new energy said in a news release, the company single crystal p-type PERC average cell production efficiency at 22. 23%. The chint cell production efficiency is above 22%, is through on the basis of the single crystal p-type PERC cell stack laser SE technology, on the spot, diffusion, sintering, the slurry screen is optimized, average cell production efficiency at 22. 23%, the highest efficiency reached 22. 55%. Through the optimization, chint PERC + laser SE cell, open pressure as high as 680 mv, a non SE battery efficiency 0. 4%.

Moore pv experimental data show that by optimizing the process of laser doping selective emitter solar cell preparation, after the SE technology, both reduced silicon wafers and the contact resistance between the electrodes, and reduces the surface of the compound, improved the life of Jane, to achieve steady improvement in battery slice production efficiency 0. More than 25%, to the component link can make existing 60 pieces of component increasing power of 5 w. Because SE is improved for the battery positive emitter, and on the back of the PERC passivation technology has the effect of the addition to each other, so applying SE in the PERC efficient battery is expected to play a better value, more production on the market at present the PERC battery manufacturers have introduced SE techniques and take effect.

in the second half of 2018, love xu solar news release, the company production single crystal PERC cell has exceeded 22%. Subsequently, Su Minxin energy single crystal PERC + SE production efficiency also reached 22 on average. 10%. In addition, P type PERC single crystal peak efficiency record 23. 95% of the holder, crystal energy, in the record (SE) has been used in cell technology.

at present, SE technology has been applied to crystal, longji, ja, tong wei xu, TRW, love a line component companies such as cell production. Which affected by photovoltaic leader base demand and capacity is the greatest love xu 5 gw solar monocrystal PERC cell line supplies, two single crystal solar, tong wei love xu PERC cell line is in a state of full capacity.

is the key to the application of SE in 2018 year, the current PERC technology has matured. Various photovoltaic enterprise in order to increase conversion rate and create differentiation with other enterprise products, select SE technology will be the first choice for various photovoltaic enterprise. By 2020, SE technology will occupy more than 50% the PERC battery market share.

according to the set consulting, a new energy research center, according to dramexchange new energy network EnergyTrend quotation since November 2018, efficient single crystal cell average quotation from 1. RMB 145 / W up to 1. RMB 225 / W; Efficient monocrystalline cells ( The conversion & gt; 21. 5%) The average bid from 1. 19 yuan/W increase to 1. 28 yuan/W. Photovoltaic industry mainstream cell enterprises ( Such as TRW, hanwha, longji, Oriental nison, ja, etc. ) , although there are single crystal PERC battery capacity, but mostly produce their own. And part of the photovoltaic capacity is insufficient, enterprise itself to the seasonal demand for overseas markets continue to production, also need to outsourcing cell, thus present a recent industry to the single crystal PERC cell demand gap bigger market as a whole.

after 531 new round big reshuffle, from flowers to the photovoltaic industry, the survival of the fittest, superior bad discard. Enterprises in order to save his life, in addition to authors efficiency of technological innovation, most took to the road to move beyond. Overseas market form, if there is a layout abroad early, increase investment in overseas markets, may soon be able to work, even in the face of the United States, India, Turkey and other countries, double anti policy, can also pass the factories overseas
