KIT intensifies printable organic solar cell research to boost efficiencies by more than 10 percent
July 04, 2012 // Paul Buckley
A group of researchers at Karlsruhe Institute of Technology (KIT) headed by Dr. Alexander Colsmann at the Light Technology Institute (LTI) are beginning to intensify a four-year project of printable organic solar cell research.
The project is aimed at enhancing the efficiency of organic solar cells to more than 10%.
The researchers are using tandem architectures combining solar cells of complementary absorption spectra. The Federal Ministry of Education and Research has granted funding of EUR 4.25 million.
The new generation of solar cells is light, flexible, semi-transparent, and allows for a low-cost production. Organic solar cells (plastic solar cells) can be applied to surfaces of nearly any shape by state-of-the-art printing and coating processes. Organic photovoltaics open up new perspectives in particular for the architectural design of buildings. The solar modules can be integrated in facades and even windows. In addition, they open up new OEM applications in the automotive or consumer sectors.
Organic solar cells are fabricated by low-cost printing and coating processes, such as gravure printing, screen printing, slot-die coating or spray coating in continuous roll-to-roll processes. Plastic carriers provide for the mechanical flexibility of the modules. At the same time, organic solar cells are characterized by a low consumption of environmentally compatible resources, unproblematic disposal, and ashort energy payback time.
Organic solar cells exhibit moderate power conversion efficiencies only. For them to be able to compete with established inorganic solar cells, extensive research is required. The early career scientists in the team of Dr. Alexander Colsmann, KIT, use tandem architectures. Two solar cells with complementary absorption characteristics are stacked directly on top of each other to achieve better sunlight harvesting and more efficient energy conversion. The KIT scientists use novel materials, develop innovative device architectures, optimize their stability, and test the solar cells in a real-life environment. Moreover, they transfer man-ufacturing processes from the laboratory to an industry-compatible production environment in order promote future commercial use of their results. “The funding of EUR 4.25 million granted by the Federal Ministry of Education and Research (BMBF) reflects the quality of our work,” said Colsmann, the head of the Organic Photovoltaics Group at the Light Technology Institute of KIT.
In this project the KIT researchers are supported by the Fraunhofer Institute for Applied Polymer Research (IAP), Potsdam, represented by Dr. Hartmut Krüger, and the University of Queensland/Australia, represented by Professor Paul Burn, who supply new materials for organic solar cells. Merck KGaA is the industry advisor of the project.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
