Monocrystalline began to replace the polysilicon market demand growth is expected to exceed 30%

This year, the PV industry continued to pick up.

Reporter According to Wind statistics, in the first three quarters of this year, 18 listed companies in the photovoltaic industry is just five losses, the rest were profitable.

Specifically, the number of polysilicon business to profitability; and monocrystalline silicon companies are usher in rapid development period, with costs continue to decrease, increased gross margins, to achieve single-crystal silicon enterprises Lungi shares in the first three quarters of net profit of 180 million yuan, greatly increased 356.59 percent year on year.

Analysts said that despite the current polysilicon dominant market, but the share of single-crystal silicon is increasing. Monocrystalline will begin to implement a partial substitute for polysilicon, market demand growth is expected to exceed 30%, higher than the overall growth of the photovoltaic industry.

In addition, the industry believes that in the long run, the photovoltaic industry development speed positive, but will remain in a deep adjustment phase.

Monocrystalline tide approaching, demand growth is expected to exceed 30%

It is worth noting that the PV market debate about the long time between the silicon and polysilicon.

PV companies in holding the 'get rich quick' idea that many people hope to buy equipment for two years to earn back. Therefore, the rapid expansion in the photovoltaic business process, many companies have chosen the route of polysilicon, first, because polycrystalline cheap, and second, because do not understand a single crystal. Currently only five or six companies producing monocrystalline silicon wafers.

But comparatively speaking, whether from the conversion efficiency or from the cost point of view, the single crystal silicon are better than polysilicon.

Under the same conditions, the higher the component generating the same amount of silicon single crystal nominal power, and a conversion rate of silicon cells is weaker than the attenuation rate of the polysilicon and higher stability.

Data show that the current large-scale industrial production of silicon solar cell conversion efficiency at 19% -20% efficiency monocrystalline silicon (HIT) can reach 23% -24%, while the photoelectric conversion efficiency of polycrystalline silicon cells in 17% - 18%. Improved efficiency monocrystalline silicon solar cells space than the polycrystalline silicon solar cells.

In addition, under the same lighting conditions, every watt monocrystalline photovoltaic power generation system than the polycrystalline high 4% -8%, and operation and maintenance costs per unit of installed capacity is less than polycrystalline. Each crystal system thus the overall cost of electricity generated is much lower than the polycrystalline systems.

Future technological progress or further widen the crystal and polycrystalline cell conversion efficiency gap. Difficult to find, silicon is being recognized by more and more companies in the market.
