Moser Baer achieves 7.3% module efficiency through its proprietary process

PV Technologies India Ltd. (PVTIL), a subsidiary of Moser Baer India Ltd. (MBIL), has successfully completed the testing and validation of a process that will enhance the stable efficiency of its single-junction amorphous-silicon thin-film module from 6% to 7.3%.

The process has been designed at PVTIL's Greater Noida plant by its in-house research team. The new method is anticipated to improve the module wattage from 340 watts per panel to 400 watts per panel on full-size modules of 5.7m2. The breakthrough has been achieved by judicious optimization of multiple layers in the device structure.

Ratul Puri, executive director at MBIL, said, "The breakthrough proprietary process will improve the viability of amorphous-silicon technology for the solar farm projects. This proprietary process is a game changer and will help us in addressing certain sections of the market by Q2 2010."

"What makes this proprietary process special is that for the first time any Indian player has achieved this level of efficiency leading to an approximate 20% cost advantage in this module size."

Dr. Rajiv Arya, CEO of PV solar business, commented, "This achievement is very timely as it has already enhanced our thin-film's capacity from 40MW to the range of 50MW and will help us reach the goals set in the National Solar Mission effectively by deploying these modules in large-size solar installations. I appreciate the efforts of our process team, which has once again demonstrated Moser Baer's innate capabilities in improving efficiency and introducing new products to cater to the demands of the market. These thin-film modules can be used for rooftop installations and for solar farms."
