Fabricating hybrid solar cells

Surrey NanoSystems has supplied Germany’s Ludwig-Maximilians University (LMU) with an advanced sputtering tool to support its research into the fabrication of hybrid solar cells.



Researchers at LMU’s Department of Physics and Centre for NanoScience will use the tool to develop production techniques that utilise ordered nanowire structures as templates for organic material. By building arrays of organic solar cells on a low-resistance nanowire interconnection substrate, researchers expect to dramatically increase the efficiency of the energy conversion process.



The tool is a configuration of Surrey NanoSystems’ Gamma tool, a plasma vapour deposition sputtering system that is highly optimised and widely used in research and development, as well as pilot production applications.



Further support for up to four sputtering target materials will provide the research team with the flexibility to deposit barrier layers and other inter-layer films to ensure good adherence of the solar cell’s active structures.



LMU’s Prof Lukas Schmidt-Mende said: ‘The high quality of film deposition that the Gamma tool can achieve gives us a very versatile platform to support our studies.’
