MUNICH<\/span>, June 24, 2026<\/span> \/PRNewswire\/ — GCL System Integration Technology Co., Ltd. (“GCL SI” or “the Company”) has announced at Intersolar Europe 2026 held from June 23 to 25 in Munich to officially establish back-contact (BC) cell technology as the core strategic pillar of its next-generation photovoltaic roadmap, as a response to the rising demand for high-efficiency, aesthetically driven solutions. It also unveiled the GPC 3.0 full-screen all-black module at one of the most influential solar industry trade fairs worldwide.<\/p>\n

GCL SI BC Modules Officially Launch in Europe<\/span><\/p>\n<\/div>\n

As China’s solar sector faces mounting efficiency bottlenecks and increasingly diverse end-market demands, the shift to BC technology is driven by both evolving market needs and the company’s accumulated expertise in passivation and contact techniques.<\/p>\n

“BC is the ultimate architecture for crystalline silicon cells,” said GengWeng Huang, Executive Dean of GCL SI’s Cell Research Division. “We’ve already explored TOPCon and HJT extensively, but both are reaching their physical limits. BC is opening a broader window for future efficiency gains.”<\/p>\n

GCL SI’s GPC (Graphical Precise-doping Passivation Contact) product line is its flagship BC technology development. GPC 3.0 targets the premium distributed segment of residential rooftops, C&I rooftops, and BIPV-style applications, where full-screen all-black aesthetics, higher energy yield, and stronger reliability are increasingly valued. GCL SI describes GPC 3.0 as a high-efficiency BC-based module designed to deliver greater real-world rooftop value.<\/p>\n

Notably, GCL SI confirmed that the first containers of GPC 3.0 modules are already on their way to Europe, marking the beginning of its commercial rollout in the European distributed solar market.<\/p>\n

The GPC residential full-screen all-black modules offer a proven benchmark: 475\u2013500 W output, 23.27%\u201324.05% efficiency, dimensions of 1,800 \u00d7 1,134 \u00d7 30 mm, a 30-year linear power warranty with 0.35% annual degradation, and a 30-year product warranty. GCL SI has indicated that GPC 3.0 is designed to further enhance both efficiency and reliability beyond this baseline.<\/p>\n

According to GCL SI, GPC 3.0 integrates several upgraded technologies including MAX design, advanced passivation, multi-layer gradient dielectric films, GPC metallization, and FBR granular silicon, to boost module efficiency, durability, and suitability across distributed scenarios. The technology offers four core advantages:<\/p>\n
