Helmholtz-Energy Alliance:

The best of two worlds: inorganic and organic hybrid solar-cells and hybrid technologies for photovoltaics

The best of two worlds: inorganic and organic hybrid solar-cells and hybrid technologies for photovoltaics

A possibility for increasing the efficiency and profitability of solar-cell solutions is available by combining inorganic and organic materials in hybrid solar-cells. For this purpose, expertise is required in two entirely different material classes. The alliance bundles precisely these classes and, in this manner, is able to crucially advance the state-of-the-art research field. Processes on the interfaces between inorganic semiconductors and conjugated organic polymers (i.e. small organic molecules) remain in the foreground of the course of this research. In order to be able to manufacture highly-efficient solar-cells, optimised nano-structures within the hybrids must be developed. In this manner, inorganic nano-particles and nano-wires with organic matrix materials are to be combined in inexpensive procedures – although embedding of organic semiconductors between inorganic nano-columns is also promising. 

Due to the complexity of the envisaged systems, the research and development of hybrid-concepts for photovoltaics shall not be discontinued after the three years of the funding period; rather, it shall be continued with a long-term perspective in the Berlin Potsdam area. On-going activities are fortified by the Helmholtz Energy Alliance insofar as an internationally visible centre for research and development in innovative hybrid photovoltaics emerges – the “Zentrum für Hybrid-Photovoltaik" jointly operated by the Helmholtz-Zentrum Berlin, Forschungszentrum Jülich, Humboldt-Universität zu Berlin, Freie Universität Berlin, Technische Universität Berlin and the University of Potsdam. This centre virtually links, on the one hand, the activities of the partners and receives, on the other, a concrete spatial home as well on the campus Adlershof in Berlin.
