SOLAR CELLS

Multi Crystalline Silicon Solar Cells XL 156mm

Multi-crystalline Solar Cells will be manufactured by XL Energy Limited in their state-of –the art, high capacity facility located at fab City – Hyderabad, India.

The process tools are housed in a clean room and comprise of acid etching, Phophorous diffusion, Silicon Nitride coating using PECVD and contacts by screen printing.

The quality of cells are continuously monitored using both in-line and off-line characterization of product and processes by well trained and highly skilled personnel.

At the end of the line , each cell undergoes an automated inspection for both visual and electrical characteristics and the cells are graded based on their characteristics.

Some of the main feature of XL Cells:

  • High efficiency, resulting in high power output.
  • Made with the help of state-of –the –art technology and using the reputed ECN process.
  • Finest quality of pastes to ensure good bonding and solderability.
  • High precision screen printing to enable automated stringing.
