The market share of single and polycrystalline solar products in the terminal market is about 2:8, mainly due to the high production cost of monocrystalline silicon wafers and batteries. The market share in the past 10 years is even below 20%, which is also insufficient. Surprisingly, but in 2015, the effective development of battery-side PERC technology has increased the efficiency of single-crystal cells, and has been well received in the terminal market. The development potential is greatly optimistic. Therefore, in 2016 and 2017, PERC became the main driving force for the expansion of the solar energy industry chain. Stepping into the mass production scale, it is expected to reduce the mass production cost.
Polycrystalline solar cells have encountered bottlenecks in efficiency pull-up. Even though polysilicon is considered a killer black silicon technology, it is expected to make great progress in terms of cost and efficiency. However, it seems that mass production maturity is still Not as expected, even the major solar farm laboratories on both sides of the strait are still actively investing in R&D and small-volume production. The relevant solar plant said that it is still not pessimistic in 2017, because each family is in full swing and has the opportunity to enter mass production.
Black silicon cells are considered to be the last layer of the current polycrystalline product to allow the city to make the walls, mainly polysilicon wafers, which can be effectively reduced by the diamond cutting method, and converted to dry or wet etching at the battery end. In order to improve efficiency, the black silicon battery will enter the city in a cost-effective manner. However, the development progress in 2016 is not as expected. In 2017, there will be a problem of insufficient security of the city wall.
Because of the fierce expansion of single-crystal PERC cells, the monocrystalline silicon wafers have also expanded significantly, and the cost-effectiveness of single-crystal products has become clearer. Monocrystalline silicon fabs insist on maintaining a “safe distance†between quotations and polycrystals. In the past two years, it was to consolidate the existing territory and not to allow a little loss. After the rapid growth of PERC, it was able to rob the city of polycrystalline solidity for many years.
The solar industry estimates that if the performance of black silicon cannot break through the current situation in 2017, I am afraid that the market share of polycrystalline will be reduced from 80% to 60%, and the single crystal will increase from 20% to 40%. Moreover, once the single-crystal PERC battery is put into mass production scale and the production cost is reduced again, it is feared that the single and polycrystalline generations will be alternately started, because the single crystal can create high efficiency space higher than polycrystalline, and become the mainstream of the market, polycrystalline In the future, there will be no chance to turn over, and the market share will probably be defeated. As in the past, the silicon film will retreat to the marginal market with extremely poor prices and gradually withdraw from the market.
The battery factory can adjust the output weight of single and polycrystalline batteries through process conversion, and the component adjustment degree is not large. Therefore, the proportion of single and polycrystalline market share is re-adjusted. The biggest impact is polysilicon fab, because single and multiple The silicon wafer process is independent and cannot be converted. Once the single crystal dominates the control, the polycrystalline production capacity will become a burden that is difficult to create a surplus.
In 2016 and 2017, the monocrystalline silicon wafers expanded greatly, and some polycrystalline plants began to cross the single crystal to avoid losing the market. The representative factories included the leading factories in mainland Longji, Central Central Europe, Poly GCL, and the expansion plan. AUO, Jingke, etc., while the polycrystalline field has made bottlenecks with existing capacity, including GCL-Poly, Saiwei, Qihui, and Taiwan Green Energy.
Single, polycrystalline solar energy in 2017 or the history of the most powerful offensive and defensive war
Abstract The mainstream P-type single and polycrystalline solar products are expected to launch the most intense territorial attack and defense in history in 2017. The market share is maintained at about 20% of P-type single crystals. With the help of high-efficiency PERC technology, there is a chance to make a big move.

The mainstream P-type single and polycrystalline solar products are expected to launch the most intense territorial attack and defense in history in 2017. The market share will remain at around 20% of P-type single crystals. With the help of high-efficiency PERC technology, there is a chance to grab a large number of The food market has a polycrystalline market that accounts for 80% of the market. Polycrystalline is not as good as expected due to the progress of black silicon cells. If the security of the city wall is insufficient, if the current situation cannot be reversed, it is estimated that the single and polycrystalline market will be changed in 2017. For 4:6, and, in the future, polycrystalline fears of a crisis of ruin and retreat.
