Delsolar, IBM to jointly develop new thin film PV technology

(ADPnews) - Sep 29, 2010 - Taiwanese photovoltaic (PV) firm Delsolar Co Ltd (TPO:3599) said on Monday it had agreed to collaborate with IBM Corp (NYSE:IBM) in the development of new efficient thin-film solar cells technology.

The new technology is based on the use of earth-abundant non-toxic and inexpensive materials, compared to the use of silicon, cadmium telluride and other components in former thin-film technologies, and is designed for commercial applications, Delsolar said in a statement.

IBM added that it has recently presented record solar cell efficiencies using copper zinc tin sulfur selenide.

The new technology can also provide enhanced spectrum sensitivity, reduced working irradiance, wider temperature latitude, notable rise in power output, and adjustable light absorbing properties.

IBM said it is already co-operating with Japanese Tokyo Ohka Kogyo Company Ltd (TYO:4186) in the development of manufacturing tooling and chemistry needed for this technology.
