PERC will undoubtedly become the mainstream of the market in the short term.

The route of single crystal replacing polycrystal was confirmed, and the market share of high efficiency single crystal gradually expanded.Monocrystalline cells have a natural advantage over polycrystalline cells in terms of product efficiency.Polycrystalline battery full application of black silicon technology, single crystal field is a large-scale popularity of PERC technology, is expected in 2-3 years in the field of polycrystalline will all be replaced by PERC technology.Due to the different crystal growth processes, the crystal quality, electrical and mechanical properties of monocrystalline silicon wafers and polycrystalline silicon wafers are significantly different from those of single crystals.Monocrystalline silicon has fewer defects, higher mechanical strength, lower fragmentation rate, greater room for efficiency improvement, higher intensification, and longer decay period.

The market share of high-efficiency single crystal is expanding gradually.With the continuous development of photovoltaic market, efficient battery will become the leading market, monocrystalline silicon battery market share gradually increase, monocrystalline silicon slice of the market share of more than 50% in 2019, as the heterojunction cell type, N PERT battery application promotion, n-type silicon slice of the market share, will also increase year by year, monocrystalline silicon slice of the market share of the future will gradually rise.

Single crystal furnace plate Jingsheng, Liancheng duopoly.According to the downstream manufacturer's planning, the new production capacity of 19GW, 26GW and 47GW from 2019 to 2021 is designed, and the demand for photovoltaic single crystal furnaces is respectively 1900, 2600 and 4700.At present, the main single crystal furnace manufacturers in the Chinese market are Jingsheng Electromechanical, Dalian Liancheng, Beijing Yuncom, etc., among which Jingsheng Electromechanical and Dalian Liancheng dominate the market, while foreign single crystal furnace equipment manufacturers have basically withdrawn from the Chinese market.

Battery equipment: short-term benefit PERC expansion, medium to see the HIT mass production process

To improve the conversion efficiency of photovoltaic cells has always been the goal pursued by the photovoltaic industry.

Photovoltaic industry mainly choose efficient battery technology route are: P type, single crystal PERC cell technology,N type single crystal PERT/ TOPCON cell technology,N type single crystal HIT cell technology and N type single crystal IBC cell technology.

In 2020, the average conversion efficiency of the mass production of polycrystalline black silicon cells reached 19.2%, the use of PERC cell technology of single crystal and polycrystalline silicon cell efficiency increased to 21.8% and 20.3%, compared with 2019 respectively increased 0.5 percentage points and 0.3 percentage points, PERC will undoubtedly become the mainstream of the market in the short term.
