On April 10, the 210 large-size microcrystalline heterojunction PECVD equipment developed by Hunan Red Sun Optoelectronic Technology Co., Ltd. was officially sent to a customer factory, which is another new milestone after the company released the special PVD equipment for large-capacity heterojunction in April 2021, marking a major breakthrough in the company's "CVD+PVD" dual-core traction strategic layout in the field of heterojunction.
Under the support of the National Photovoltaic Equipment Engineering Technology Research Center platform, the company has been committed to the research and development of heterojunction PECVD equipment, and has launched the first generation of principle machine, the second generation of quasi-mass production machine and the third generation of mass production machine in the past two years, and the main engine adopts I-IN-P structure combination and with automation overall solution. The equipment adopts modular design, which has a unique design and intellectual property layout in terms of automatic and rapid regulation of silicon wafer temperature, rapid improvement of large area carrier board, rapid response of RF feed-in, large-area multi-layer cloth air spray board and uniformity control of capacitive coupled RF plasma field, etc., which can realize single-sided or double-sided microcrystalline process, help customers achieve 25%+ high efficiency goals, and release the green value of heterojunction cells.
At the same time, the company's PVD equipment has also been reported frequently, and the key technical indicators of the equipment are leading in the industry, and the orders of the head enterprises have been obtained successively. The company will further consolidate the technical foundation, focus on the localization of heterojunction high-end photovoltaic equipment, and boost the cost reduction and efficiency of the photovoltaic industry and high-quality development.
