Guangdong Golden Glass Technologies Limited(300093) on April 10, the official wechat showed that the battery efficiency of Guangdong Golden Glass Technologies Limited(300093) heterojunction production line exceeded 24.5%. This means that the production line has reached the expected conversion target after more than three weeks of the whole line. It also shows that Suzhou Maxwell Technologies Co.Ltd(300751) the first mass production microcrystalline process production line still has great potential in improving the conversion efficiency.
On June 28, 2021, Guangdong Golden Glass Technologies Limited(300093) announced that it would invest 832 million yuan in the construction of 1.2gw large-size half chip ultra-high efficiency heterojunction Cecep Solar Energy Co.Ltd(000591) battery and module project, which is expected to generate more than 2 billion yuan of sales revenue every year after its completion.
It is understood that the project adopts half chip front-end process, 210 large size, the largest single scale, and the final module power exceeds 700W. It is the world’s first and leading enterprise of photovoltaic equipment Suzhou Maxwell Technologies Co.Ltd(300751) hjt equipment, the first GW level whole line delivery and hjt3 First order for 0 device. Using the whole line heterojunction equipment developed by Suzhou Maxwell Technologies Co.Ltd(300751) and equipped with MES tracking system, it can realize large-scale mass production chip level tracking and traceability, realize accurate online process control by using big data, and realize digital intelligent manufacturing.
On March 12, 2022, Guangdong Golden Glass Technologies Limited(300093) heterojunction battery production line was connected with streamers, and the battery conversion efficiency was 24.28% in the first phase.
Tianfeng Securities Co.Ltd(601162) research report points out that Guangdong Golden Glass Technologies Limited(300093) heterojunction production line mainly has four innovations: first, half piece 210 specification is adopted for GW level whole line for the first time, second, chain impurity absorption equipment is adopted in mass production for the first time, third, high-efficiency coating process is tried with mass production equipment for the first time, and fourth, new concept automatic production line is tried for the first time. At the same time, at present, the team members have rich production experience in the photovoltaic industry, gathering heterojunction cell production experience, traditional crystalline silicon cell industry experience, amorphous silicon cell production experience and semiconductor industry experience. At present, the team can make full use of their respective advantages to ensure the promotion of heterojunction photovoltaic projects.
After overcoming many unfavorable factors including epidemic situation, Guangdong Golden Glass Technologies Limited(300093) recently successfully started the microcrystalline process commissioning of CVD equipment in 210 heterojunction battery production line. After the first round of microcrystalline process parameter optimization for nearly a week, by April 9, under the condition of multiple groups of optimized parameters, the maximum conversion efficiency of the battery reached and exceeded 24.5%, and the average value was close to 24.3%.
Guangdong Golden Glass Technologies Limited(300093) said that next, the technical teams of both sides will quickly carry out the second round of production parameter optimization and challenge to achieve the target of 25% mass production efficiency.
