LG Quality The solar modules produced by LG meet the most stringent quality criteria – guaranteed by one of the world’s leading electronics companies.
Our state-of-the-art manufacturing facilities are designed to produce high quality, high performance cell and panels that come ready to perform
Each wafer is thoroughly examined and measured to eliminate defects, so only the best-quality wafers are selected.
Selected wafers then undergo a wet etching process where the surfaces are immersed in acidic (multi) and alkaline (mono) solutions to help reduce light reflection.
N-type emitters are formed by loading P-element POCI3 gas into P-type wafers.
The wafers are then coated with an anti-reflective (SiNx:H) film through a PECVD method which uses SiH4 and NH3 to reduce reflection and improve transmission.
Metallic electrodes are composed to gather activated electrical carriers (electrons and holes) for each cell.
Cells are finally measured and sorted by efficiency, as well as being classified by colour and electrical characteristics.
Each incoming wafer is checked again to eliminate any faults and defects.
Cells are then welded with strings by busing ribbons to meet the required power output.
Cells are assembled with layers of glass, EVA film and back sheet to protect them from external damage.
These layered modules are then encapsulated to protect the cells from water infiltration.
Modules are installed with a junction box for electrical connection and framed to ensure mechanical strength.
Each module is tested under simulated conditions to check output performance and classified accordingly before completion.
