Moser Baer tips 7.3% efficient a-Si modules

Moser Baer says it has upped the conversion efficiency of its amorphous silicon single-junction thin-film modules from 6% to 7.3%, which translates into a module wattage improvement of 400W/panel from 340W/panel (for full-size 5.7m2 modules).

March 11, 2010 – Moser Baer says it has upped the conversion efficiency of its amorphous silicon single-junction thin-film modules from 6% to 7.3%, which translates into a module wattage improvement of 400W/panel from 340W/panel (for full-size 5.7m2 modules).

Key to the improved efficiency is “judicious optimization of multiple layers in the device structure,” which Ratul Puri, executive director of Moser Baer India Limited, called “a game changer” in a-Si technology for solar farms that will help the company “address certain sections of the market” as soon as the current quarter (2Q10). He also emphasized that the achievement is from an Indian company.

Besides improving module efficiency and wattage, the upgrade offers a ~20% cost advantage, and has helped the company increase its thin-film capacity from 40MW to ~50MW, added Rajiv Arya, CEO of Moser Baer’s PV solar business.

Besides its thin-film segment, Moser Baer says it also has about 80MW capacity each for crystalline solar cells and modules, and a few MW for concentrated PV.
