December 19, 2023 -  DAS Solar, a leader in N-type technology, attended the High Efficiency Solar Technologies 2023 virtual conference, showcasing its latest N-type products and technology. The virtual conference deep-dived into current technological status and development trends in the photovoltaic industry.. A keynote speech entitled "DAS DAON Leading N Time" was delivered by Mr. Alex Chen, the Overseas Technical Support Manager of DAS Solar Sales technical support department, during the TOPCon technology session on the 19th.

DAS Solar is dedicated to continuous exploration and rigorous research in N-type technology, consistently surpassing industry standards in cell and module efficiency. As Alex Chen pointed out in his speech, the DAS Solar N-type TOPCon 4.0 technology incorporates a new charge carrier transport mechanism, a new structure, a new Poly-finger technology, and a new material application. It has exceeded 26% efficiency in mass production. Equipped with DAS Solar's cutting-edge TOPCon 4.0 cell technology, the cell achieved an impressive cell laboratory efficiency of up to 26.33%, and the 735mV open circuit voltage record, making it the world's highest open-circuit voltage TOPCon solar cell, demonstrating its technological advantages in the N-type technology.

To maximize value across the entire supply chain, DAS Solar collaborates with several leading enterprises to standardize rectangular product dimensions, following the development philosophy of collaboration and mutual success. This initiative encourages the integration of the industry supply chain, reducing various costs, including manufacturing, maintenance, installation, and operation.Recently, a 72-cell N-type 4.0 module was officially launched. Module conversion efficiency is 22.8% with a power output of 615W. Comparing the past design, it demonstrates high bifaciality, efficiency, and low attenuation, resulting in a 30W increase in module output power and lower system BOS costs as well as LCOE.

DAS Solar modules have demonstrated outstanding performance in multiple outdoor tests and N-type products shipments rank among the Top 3 globally. DAS Solar will continue to contribute to global green and sustainable development through technological innovation in the future.
