Jinergy Attended the “HJT and Tandem Technology Industry Summit 2023” and Shared its New Progresses in R&D
What is the latest progress of HJT cost reduction technologies? What is the development trend of tandem cell? How to achieve high-quality development for enterprises in HJT in the future? With the exploration of these questions and its latest technological progress, Jinneng Clean Energy Technology LTD. (hereinafter referred to as “Jinergy”) attended the “HJT and tandem Technology Industry Summit 2023” jointly sponsored by SOLARZOOM and Soochow Securities to discuss the cutting-edge issues of HJT and key future technologies.
Yin Jinjie, Jinergy’s Product Manager, shared in his speech themed by Jinergy Research Progress of HJT and tandem Technology, “Jinergy has followed the technology iteration strategy, industrialized the advanced reserve technologies in the critical period of N-type iteration, and steadily improved the efficiency of mass production of HJT. Meanwhile, we have achieved certain results in the development of perovskite+ HJT tandem technology, thus providing high-efficiency and high-reliability N-type products that meet the market demands by lean production. The first phase of Jinergy 8GW TOPCon high-efficiency cell project will be put into production soon. By then, N-type products will account for more than 80%, and the efficient production capacity will facilitate the high-quality development of the Company.”
HJT has always been the R&D focus of Jinergy. Jinergy owns many patented technologies, which are gradually implemented with the promotion of the cost reduction in the whole industry chain. Jinergy has carried out continuous work in phases on technologies such as bifacial microcrystal and optimization, 0BB, structure optimization and metallization optimization, aiming to achieve the efficiency target of 26%.
China Solar Industry Association predicts that by 2025, the total proportion of ultra-efficient cell technologies represented by HJT and TOPCon will be close to 40%, and is expected to exceed 75% by 2030. Higher efficiency and lower cost are the key for the industry to betting on HJT while shorter processes allow more room for later cost reduction and the development of products with lower carbon value. With its own transparent conductive oxide (TCO) layer, HJT can be perfectly matched with the perovskite layer, thus to break the efficiency limit again. In the perspective of future layout, perovskite/HJT tandem cell is also a new focus of Jinergy’s “one generation in R&D.
Jinergy’s R&D team has worked with higher research institutes to utilize vacuum evaporation method to develop the 400cm² perovskite film. Meanwhile, it has made new progress in the controlled production of the core technology NiOx hole transport layer, the research on the photoelectric performance of IZO transparent electrode thin film, and the production of high-performance perovskite solar cell modules by cured in place pipe (CIPP) method. Mr. Yin introduced in his speech that, “At present, Jinergy has achieved the efficiency of 25.05% in small-area perovskite cells, 28.5% in small-area calcium-silicon tandem cells, and nearly 19% in perovskite modules. By now, Jinergy has built the calcium-silicon tandem cell demonstration line and produced large-size cell samples.”
Specifically, HJT/perovskite tandem cell represents the future. In Jinergy’s layout of “one generation in mass production”, with considering investment intensity, conversion efficiency, industrial chain maturity and other aspects, Jinergy has regarded TOPCon as the iterative product of Jinergy’s mass production in the period of industry restructuring, aiming to provide more valuable product programs for terminal customers in the market. In the future, with the gradual breakthrough in the cost of HJT equipment and materials, high-tech products with more cost advantages will be launched, and flexible manufacturing will meet the diversified needs of customers. Jinergy will pay attention to the low-carbon nature of the whole life cycle of the products, and reduce the cost of ICOE to help the terminal obtain higher green income.
