Perc: How to cast high-efficiency photovoltaic beyond

　　Author ：Iflowpower – Portable Power Station Supplier

MEYERBURGER's equipment orders have soared again, and PERC-related equipment is the core of this order, which is reported that the supply of PERC processing line has continued until the second half of 2016. In many high-efficiency photovoltaic cell technology routes, PERC has protruded from the recent foreign military, and became a route for the first-line company. The demand for high-efficiency components and the opportunity of Perc EnergyTrend counts the demand for components in the second quarter of 2015 2015.

The components of the 72-piece cells in the US market exceeds 70%, of which more than 310 watts of components are about 50%; in the Japanese market, the 60-piece power of 260-tile power is more than 25%; in the UK market The 60-piece component share of 260-watt-above power is close to 50%, of which 275 watts are occupied by more than 10%. With the demand for high-efficiency components, the mainstream component companies have begun to adjust their production line layout strategies. my country's market's demand for high-efficiency components has increased significantly in the second half of 2015, and it is desirable from my country's related government departments.

This year, only the 1GW leader base was approved. In 2016, the leader base or will exceed 4GW installed, and the salesman components such as Ningxia, the Xindong New Energy Base require the leader component, 2016 or will have more than 6GW leaders. Component demand.

In accordance with the 2016 20GW measurement, my country's high-efficiency component proportion will exceed 30%. Since most of our production meets the requirements of the leadership plan, the new new network and some processing lines have become the focus. Several high-efficiency technology routes such as IBC, Hit, PERC, Perl, Pert have already produced mass production and pushing market.

As a high-efficiency battery leader, Sunpower is a representative of IBC technology, but its n-type single crystal IBC battery is not pushed away from prices; HIT's representative company is the Panasonic acquired Sanyo, and its market price is about $ 1 /watt. The battery mass production efficiency of the two companies exceeds 23%, and the price of the components is 1 US dollar / tile. The former is lowered by low-dimensional reduction; the latter's market is in the high price subsidies Japan.

Although my country has purchased a HIT processing line from Meyerburger, as the market's demand for high-efficiency components is getting higher and higher, PERC technology route with general assembly price difference is gradually paying attention. Since PERC technology can complete the transformation of processing lines as long as it adds two devices, this technology has been attached importance to, Tianhe Light, Crystal, British, Atters, Hairnge, etc. in the past two years.

Technical mass production components, Le Ye Photovoltaic, Jincheng integration, Jinneng Technology, etc. are preparing for the mass production of PERC components. Bloomberg Dramatory Master Wang Ting Ting said that PERC battery market share is expected to increase from 4% in 2014 to 6% in 2015, and 61% in 2018.

According to ENERGYTREND Decomposition Teacher Lin Yulin, the recent 270 watts of polycrystalline PERC components is 0.59—0.63 US dollars / watt, 280—285 watts of single crystal PERC components about 0.

6—$ 0.7 / tile. Plus tax and conversion of currency approximately 4.

5 yuan / watt. It is understood that in the bidding of a 100MW leader project in China, the 280W single crystal component exploded the price below 4.2 yuan / watt, which is lower than the 270W polycrystalline component bidding price, showing single crystal in high-efficiency products.

Higher efficiency is a higher power of single block components. The corresponding cost per watt balance system will decrease, and the PERC component starts to reduce the cost-effective gap between the conventional products on the market. As for the total life cycle of the whole life.

It is still waiting to be observed in competitiveness. Lin Yuling said that the PERC production expansion of each manufacturer will cause the price to decline, but it is expected that the roof distributed market in the United States, Japan, Europe, Australia, etc. will continue to rise, and the demand for high-efficiency components will be stable and improved.

If the PERC trend can use a general P-type single crystal, the battery efficiency can achieve the efficiency of 19.8%, if you do not need PERC technology, it is difficult to over 20%. After the battery team goes to PERC processing line, after the internal decision is a large-scale adoption of PERC technology, Dang Yiping, the integrated director of Rongji Shares, said that through Perc Technology, our battery efficiency can be 20.

5%, after a period of development can reach 21%. Longji stock subsidiary Le Ye Poap is in Jiangsu Taizhou layout 2GW high-efficiency PERC single crystal battery processing line. PERC, which means passivated emitted back contact (passivated), only through the back passivation and two new steps of the laser engrave groove, and the cost of processing lines can be completed, and the cost is about 30 million yuan.

According to Lin Yonglain, the cost of each watt cell film after PERC technology has increased by about 4 cents, about 0.25 yuan. However, accordingly, the number of watts of each piece of the battery is improved, which reduces the cost of wafer per watt.
