Texturisation, phosphorus diffusion, tunnel oxide deposition, PECVD AR coating, and silver/aluminium metallisation. Each cell flash-tested individually.
04
Module Assembly
Lamination & Framing
Cells tabbed with bus bar ribbons, laid on low-iron glass with EVA encapsulant, vacuum-laminated, framed, and fitted with junction boxes.
05
Quality Testing
IEC 61215 / 61730 Testing
Flash testing, EL imaging, thermal cycling (−40°C to +85°C × 200 cycles), damp-heat 1000hr, hail impact, and PID resistance verification.
06
Dispatch
Certified Global Dispatch
Unique serial numbers, IEC 62759-compliant packaging, quality certificates, test reports, and performance warranty documentation with every order.
Manufacturing Stages
01
Ingot Growth
Silicon Crystal Growing
High-purity polysilicon is melted at approximately 1,420°C and transformed into mono-crystalline silicon ingots through the advanced Czochralski (CZ) crystal growth process. Automated thermal control systems ensure precise crystal orientation, uniform resistivity, and ultra-low impurity levels essential for high-efficiency N-Type TOPCon applications.

02
Wafer Slicing
Diamond-Wire Cutting
Mono-crystalline ingots are precision sliced into ultra-thin wafers using advanced high-speed diamond-wire cutting technology. The wafers undergo ultrapure water cleaning, EL inspection, thickness calibration, and resistivity-based grading to ensure maximum downstream cell efficiency and manufacturing consistency.
