Winchester, UK - Germany's Federal Ministry of Education and Research (BMBF) is supporting a future oriented development project through a consortium that is headed by Konarka Technologies, Inc., and is providing funding of nearly EUR 2.5 million over the next three years.

The project, called 'OPV stability' aims to increase the lifespan of organic solar cells (OSC) with the goal of yielding competitive organic photovoltaics (OPV) for potential commercial use.

Established to develop stable organic solar modules, the consortium consists of academic partners including University Tubingen, University Wuppertal, Julius-Maximilians-University Wurzburg, Ludwig-Maximilians-University Munich and the Max-Planck-Institute for Polymer Research in Mainz.

"The partners of this BMBF initiative are participating to break through technological and economic barriers in innovation in the field of organic photovoltaics," commented Christoph Brabec, CTO at Konarka, an innovator in development and commercialization of Power Plastic. "We are expected to make significant contributions to extending the lifespan of organic solar cells, ultimately delivering future organic photovoltaic technology with increased commercial attractiveness."

Organic solar cells are flexible, semi-transparent and inexpensive to produce but existing barrier materials result in a limited lifespan. Higher life expectancy can only be realized by combining high-quality encapsulation with high intrinsic stability of photoactive materials, which is the focus of the BMBF Stability Project. There have been many improvements in OSC technology in the recent past, but due mostly to improved packaging of cells rather than an extension of the lifespan.

The BMBF is also supporting another future-oriented development project by a consortium of companies, including Konarka, which aims to develop innovative polymeric solar cells for energy-autonomous systems. The BMBF Efficiency Project is expected to yield solar cells that are optimized for specific applications with efficiencies of more than 10 percent and are highly competitive with other PV technologies.
