Oerlikon Solar uses TCO contacts to reach 10% efficiencies with single junction a-Si cell

Recently verified by the U.S. National Renewable Energy Laboratory (NREL), Oerlikon Solar has repeatedly reproduced amorphous silicon (a-Si) single junction PV cells with stabilized conversion efficiencies of over 10%. The company said that this was a new record for single junction cells and was achieved with the use of its proprietary TCO front and back contact technology.

“We successfully implemented several innovative modifications of key processes, leading to this new record in stabilized cell efficiency which presents a historic milestone for amorphous silicon technology,” noted Dr. Johannes Meier, CTO Thin Film at Oerlikon Solar: “We are confident that our ability to repeatedly achieve record results can be transferred into mass production soon.”

Oerlikon Solar said that they expect to have customers in commercial production with this technology by the end of 2010 and achieve module conversion efficiencies of 10% or more.

Photovoltaics International 16th Edition

This sixteenth edition of Photovoltaics International marks four years of production of the quarterly journal. As always, our focus is on efficiency and quality improvement and cost reduction in manufacturing. As 2012 rolls along, companies are falling by the wayside due to supply and demand issues, ASP declines and drastic governmental subsidy cuts. A clear picture of 2012 is offered through papers from the likes of TÜV Rheinland, Fraunhofer ISE, SEMI PV Group and EPIA, amongst others.
Photovoltaics International Lite, Volume 05 - 2011

This digital interactive Lite sees Tom Cheyney follow Agua Caliente’s progress on becoming one of first truly utility-scale PV power farms, where 40–50MW (AC) will be commissioned by the end of the year. We also feature one of the world’s largest silicon thin-film PV power plants, Avenal; a report on warnings of the collapse of module prices from Solarbuzz and PI-Berlin presents tips on PV module testing. A print version of this edition will be distributed at Solar Power International 2011 in Dallas, Texas.
