Standards Enhance Cohesiveness and Efficiency for China’s Photovoltaic Manufacturing Industry

Standards Enhance  Cohesiveness and Efficiency for Chinas Photovoltaic Manufacturing Industry

SEMI China PV Standards Technical Committee 2014 Annual Fall Conference held in Dalian

By SEMI China

For a long time, photovoltaic (PV) power generation has been a “hot topic”  in the industry with many reports in the news — including  the introduction of the “Eight Real Estate Market Regulation Measures” in China in 2013; the implementation of PV ground station grid-generated electricity sales prices and distributed generation subsidies; the increase of China’ installed capacity for PV power generation over to 13GW in 2013; and the large investment of private capital China Minsheng Investment Co., Ltd. into PV power generation..

In contrast to the bright focus on PV power generation,  China’s PV manufacturing industry, which experienced an unprecedented market depression and  industrial integration, is accustomed to painstaking efforts to make progress.  Forging ahead SEMI China, which leads and is supported by PV manufacturing standards, is devoted to re-building a solid foundation and enhancing the cohesiveness and efficiency of China’s photovoltaic manufacturing industry.

On September 12th, 2014, the SEMI China PV Standards Technical Committee 2014 Annual Fall Conference was held in the Dalian Shangri-La Hotel. The conference was the 11th meeting held since the inception of the SEMI China PV Standards Committee at the end of 2011. This conference put forward and discussed 11 standards proposals in all, including six proposals for SEMI global standard round-five voting feedback standards, two proposals for SEMI global standard round-seven voting standards, and three proposals for new standards.

During the conference, committee members discussed the feedback and revisions for the six standards involved in the SEMI 2014 global standard round-five voting. The six standards include:

  • Specification for Framing Tape for PV Modules proposed by Yingli
  • Specification for Ultra-thin Glass for PV Modules proposed by Trina Solar
  • Terminology for Back Contact PV Cell and Module proposed by Sibco
  • Specification for Aluminum Paste, Used in Back Surface Field of Crystalline Silicon Solar Cells proposed by Suntech Power
  • Test Method for Determination of Total Carbon Content in Silicon Powder by Infrared Absorption after Combustion in an Induction Furnace and Test Method for the Measurement of Chlorine in Silicon by Ion Chromatography proposed by GCL.

After discussion and voting by the attending committee members, these six standards proposals were all placed into the review process for SEMI global standards, and are close to their final release.

In addition, three new standards proposals were submitted to the Committee for review and formal filing by the vote of the attending committee members. The three new standards proposals include:

  • Detection Method for Microdefects in PV Modules proposed by Changzhou Trina
  • Guide for Material Requirements of Internal Feeders Used in Mono-crystal Silicon Growers proposed by Dalian Linton
  • General Technical Requirements for Electroluminescence Defect Detection System for PV Modules proposed by the China Photovoltaic Industry Measurement and Testing Center (prepared)

The conference also passed these proposals, moving them into the SEMI 2014 global Standard “Round 7” voting phase:

  • Specification for Quasi-Monocrystalline Silicon Wafers for Photovoltaic Solar Cells

Test Method for Determining B, P, Fe, Al, Ca Contents in Silicon Powder for PV Applications by Inductively-Coupled-Plasma Optical Emission SpectrometryIn addition, Mrs. Sheng Hong, SEMI China Standards Manager, notified the group of recent activities about global SEMI  Standards activity.  As of the end of August 2014, SEMI has released 912 effective standard items and 54 photovoltaic standard items.

The eight restructured task forces reported the status and progress of their respective work after the restructuring by their respective representatives. Currently, the SEMI China Photovoltaic Standards Committee has set up eight task forces:  photovoltaic silicon raw materials, photovoltaic silicon wafers, crystalline silicon solar cells, photovoltaic modules, silicon thin film photovoltaic modules, photovoltaic diffusion furnace testing, multi-wire cutting wire saws, and photovoltaic power plant equipment integration efficiency.

Up until now, the SEMI China Photovoltaic Standards Committee has released six photovoltaic standards worldwide, and has 19 standards under development. Since its inception in December 2011, the SEMI China Photovoltaic Standards Committee has used SEMI’s advanced standards model  for organizing, formulating, and releasing technical standards. SEMI China has attracted leading domestic and international PV manufacturing, materials and equipment companies to be actively engaged in PV standard formulation activities, and set up a core technical committee consisting of 28 veteran technical experts in the photovoltaic industry.

Nearly 110 representatives from SEMI China, Dalian Linton PV & SEMI Machine, JA Solar, Yingli Solar, Canadian Solar, the National Center of Supervision and Inspection on Solar Photovoltaic Product Quality (CPVT), Trina Solar, Suntech, GCL, GD Solar and 41 other organizations participated in this conference, which was chaired by director Liu Jun. In addition, Dr. Haoan Lu, vice president of SEMI Global and Miss Jun Liu, SEMI China PV Standards Committee Chairman, issued SEMI China PV Standards Technical Committee Honor Certificates to two new committee members, Dr. Xinmin Huang from JA Solar and Dr. Da You from GCL.

The SEMI China PV Standards Core Technical Committee heldits next meeting will be held in Changsha on December 5, 2014.
