Focusing on Market Concerns and Responding to Customer Needs

As an important market hub at the intersection of Europe and Asia, Turkey and its surrounding regions have seen growing demand for high-efficiency, reliable photovoltaic products. For customers, stable mass production capacity, multi-scenario adaptability, and whether products can deliver higher value at the application end have become key areas of focus.

In response to these market concerns, on April 9, Xiao Feng, Senior Engineer of Overseas Customer Service at the Platform Quality Department of Tongwei Solar, gave a systematic introduction to the mature mass production foundation, performance, and application potential of the TNC series high-efficiency cell products in her presentation. Based on the mature mass-produced N-type technology platform, Tongwei can stably mass-produce TNC cell products with a conversion efficiency exceeding 26.3%, maintain stable performance under diverse operating environments, and continuously unlock higher power potential for module manufacturers.

From TNC 1.0 to TNC 3.0: Continuous Advancement in Product Capability

During the presentation and exhibition, from TNC 1.0 to the TNC 3.0 quarter-cut product highlighted this time, Tongwei continuously demonstrated the iterative upgrade path of the TNC series high-efficiency cell products. Among them, the TNC 2.0 half-cut product has been continuously optimized in terms of efficiency performance, power gain, and module compatibility; the TNC 3.0 quarter-cut product has further improved in power output, safety performance, and edge passivation, enabling a module power gain of over 10W, a 5% increase in bifaciality, and a conversion efficiency exceeding 26.3%, bringing more value-added space for high-efficiency modules.

The value of Tongwei's TNC series high-efficiency cells lies not only in the continuous improvement of performance parameters, but also in the comprehensive performance in terms of power output, reliable operation, scenario adaptation, and value delivery. Following this direction, Tongwei has always been committed to promoting product iteration and upgrading, and continuously improving product adaptability and application potential.

Strengthening Customer Trust Supported by Intelligent Manufacturing and Service

Behind product capability lies stronger manufacturing and service support. Relying on the world's first lighthouse factory in the global PV cell industry, Tongwei's leading "cell-level tracking" system, and full-process quality control capabilities, Tongwei Solar continues to consolidate the stable and reliable quality foundation of its products. Meanwhile, in response to overseas market demand, Tongwei Solar provides services including rapid response, on-site support, technical consulting, and process optimization, further strengthening long-term connections with customers.

Looking forward, Tongwei Solar will continue to promote the iteration and upgrading of TNC series high-efficiency cell products based on market demand. With more competitive product capabilities and clearer value proposition, Tongwei will continue to demonstrate greater potential of its high-efficiency cell products in terms of efficiency improvement, power gain, and value release to the global market.
