Oerlikon touts >10% a-Si cells

Oerlikon Solar says its amorphous silicon single-junction photovoltaic cells have reached an NREL-confirmed >10% conversion efficiency, proven in a repeatable process.

September 23, 2009 – Oerlikon Solar says its amorphous silicon (a-Si) single-junction photovoltaic cells have reached an NREL-confirmed >10% conversion efficiency, proven in a repeatable process.

The record mark, achieved thanks to what the company’s thin-film CTO Johannes Meier called “several innovative modifications of key processes” — including proprietary TCO front and back contacts — “serves as basis” to push the company’s achieve Micromorph PV technology to production modules with stabilized efficiencies of 10% or more.

He said the company is confident the record-efficient cells would be transferred to mass production “soon,” with price-competitive (vs. conventional energy) PV module production lines ready by the end of 2010.
