Konarka Processes Organic Solar Cells Via Inkjet Printing

Konarka Technologies Inc., developer of Power Plastic material, has conducted the first-ever demonstration of manufacturing organic bulk heterojunction solar cells via inkjet printing.

‘Demonstrating the use of inkjet printing technology as a fabrication tool for highly efficient solar cells and sensors with small area requirements is a major milestone,’ says Rick Hess, president and CEO of Konarka. ‘This essential breakthrough in the field of printed solar cells positions Konarka as an emerging leader in printed photovoltaics.’

Inkjet printing is a commonly used technique for controlled deposition of solutions of functional materials in specific locations on a substrate and can provide easy and fast deposition of polymer films over a large area, the company says.

The demonstration confirms that organic solar cells can be processed with printing technologies with little or no loss compared to clean-room semiconductor technologies, such as spin coating.
