ZNShine showcases graphene-coated TOPCon module range
ZNShine has introduced a new line of graphene-coated TOPCon photovoltaic modules designed for various applications, including utility-scale projects and load-bearing roofs. The graphene coating provides self-cleaning properties and increased mechanical durability.
Why it matters
Advancements in solar module efficiency and durability are critical for the global transition to renewable energy and reducing operational costs.
ZNShine recently showcased a range of graphene-coated TOPCon PV modules, spanning a quarter-cut high-efficiency module, a busbar-free module for utility-scale projects, and a lightweight module aimed at roofs with load-bearing limits.
The 670 W module uses 264 G12R-size quarter-cut cells interconnected in a gapless design that increases the module's active area, reaching a maximum efficiency of 24.8%. Shorter cell busbars reduce resistance and lower power losses compared with half-cut cell designs. Open-circuit voltage is 50.90 V and short-circuit current is 16.54 A. The module is laminated with front and rear glass and framed in steel rather than aluminum for added mechanical durability in ground-mounted utility or C&I installations, and measures 2,382 x 1,134 x 30 mm.
