Polycrystalline silicon black PERC battery production line.
Recently, GCL Integration announced that the average efficiency of its high-performance polycrystalline silicon PERC battery mass production continued to achieve a breakthrough on the basis of 20.5% at the end of 2017, with the highest efficiency exceeding 21% to reach 21.3%. Polycrystalline 60 version module power Breakthrough 300W, once again refresh polycrystalline PERC battery production efficiency.
It is understood that GCL has started mass production of black silicon PERC batteries based on diamond wire cut polysilicon films since February 2017. Currently, GCL's integrated high-efficiency battery production capacity is 2GW, and it will reach 3GW in 2018. It is 295W more. The crystal black silicon module participated in the bidding for the front runner project. The conversion efficiency of this component was 17.9%, which exceeded the national leader's component efficiency of 0.9%, and reached the highest power requirement for the components of the leading project.
'Every time the efficiency of GCL's integration is based on breakthroughs in fully mass-producible technologies, it is not limited to laboratory or pilot line technologies and efficiency, and the cost per watt of batteries and components continues to decrease. These high-efficiency and low-cost The battery and components can be quickly mass-produced to bring significant economic benefits. '
Industry analysts stated that the goal of the PV industry is to access the Internet at a parity price, and the PV market will always favor the products that contribute more to cost-effective Internet access and more cost-effective products. From the perspective of market conditions, market share occupies 80% of the third batch of front runner projects. The polycrystalline remains as the main force of the cheap internet route. In the future, the market share and trend of polycrystalline and single crystal will be more determined by the market.
Wang Bohua, secretary-general of the China Photovoltaic Industry Association, once said in a public speech: 'Highly cost-effective products are a solid foundation for PV's affordable access to the Internet.' In the past five years, the costs of all aspects of the industry chain have fallen by half, 2016-2017, The decrease in PV module prices still reached nearly 21%. The decline in the cost of modules lays a solid foundation for the PV grid to access the Internet and large-scale deployment. High-efficiency polycrystalline wafers are the first choice for cost-effective products, and have become the main force for cheap Internet access.
The relevant research data shows that the efficiency of polysilicon cells has huge room for improvement, and the efficiency breakthrough of the German institute also provides examples. The efficiency of polycrystalline cell industrialization can reach over 21%, and the optimistic estimate can reach 22%. Jia Rui, director of the Center for Applied Research of Solar Cells and Systems at the Institute of Microelectronics of the Academy of Sciences, once predicted that: 'With the development of diamond cutting, black silicon, and PERC technology, high-efficiency polycrystalline products will also dominate the market in the next three to five years. Status. '
The cyclical, continuous technological progress and iterations of the photovoltaic industry have brought about continuous reductions in product costs, and the rapid expansion of market and industry scale. This time, the average efficiency of GCL's integrated polysilicon PERC battery production reached 20.8%. , will greatly promote the continuous progress of the photovoltaic industry.
