Application of Cutting-edge Technologies Sets New Tone for Industry Development – JINERGY Speeds up the Mass Production of HJT
Recently, with the release of the list of the third batch PV Top Runner Program by National Energy Administration, constantly strengthening technological innovation, focusing on the key industrial technologies and speeding up the transformation and application of cutting-edge technological achievements have already set a new tone for the PV industry of new age.
In face of the new opportunities brought by accelerated transformation and upgrading of new energy industry, the PV practitioners have speeded up the R&D and mass production of cutting-edge technologies with an aim to promote the early realization of PV power generation at grid parity. Since recent years lots of innovative technologies like PERC, N-type PERT and non-crystalline silicon/crystalline silicon HJT have emerged constantly and JINERGY, the leading PV modules manufacturer of Shanxi Province has taken a lead in R&D and mass production of HJT.
At the 2nd N-type crystalline silicon cell and bifacial generation forum held today (December 12th), LI Gaofei, Technical Director of JINERGY made a share themed by “Introduction of HJT Mass Production”. According to the introduction, HJT is featured by simpler processes, no LID, no PID, low temperature coefficient and bifacial generating capacity in comparison with other conventional module technologies. So far the 280W polycrystalline PV modules and 305W PERC monocrystalline PV modules of JINERGY have already realized mass production, the innovative HJT 60-cell bifacial modules have passed the test of TUV and their power reached up to 344W, the mass production power of HJT 60-cell modules has reached 340W, and the cell mass production efficiency has exceeded 22.5%.
However, the mass production of HJT is still faced with many difficulties. LI Gaofei expressed, “In comparison with N-type products, HJT has raised a much higher requirement on the silicon quality itself; meanwhile, the Q-time control is very strict in each process; and structure of double-glazed double-sided modules further increases the difficulty of series connection of cells.”
While overcoming the technical difficulty, JINERGY also makes a dedicated cost-reduction plan to address the high-cost issue during mass production of HJT. Through analysis LI Gaofei expressed, “at present, wafer, conductive silver fluid, target material and flocking additives account for a big proportion of the cell BOM cost. For this case, JINERGY plans to work together with suppliers to develop a fire-new conductive silver fluid, optimize the amount of consumables, and meanwhile achieve cost reduction and efficiency improvement by developing fire-new target materials. By the year of 2018, the gap between the overall cost of HJT products and conventional polycrystalline products is around 30%, and this figure is expected to decrease to 20% or less”.
