Description: Das Projekt "Interface texturing for light trapping in solar cells" wird vom Umweltbundesamt gefördert und von Ecole Polytechnique Federale de Lausanne, Institut Interdepartemental de Microscopie Electronique durchgeführt. The project investigates light absorption in thin film silicon solar cells, one of the leading technologies for the generation of low cost of renewable energy. Because silicon is a rather weak absorber, light scattering at interface textures is used to enhance the absorption. Understanding of light scattering and the corresponding absorption enhancement in the device represents a scientific challenge that spans optics, device physics and material science. Among the textures used so far, solar cell technology makes use almost exclusively of random structures that develop during the growth of on of the of supporting films or the substrate. The idea of the project is, to understand the details of the scattering event, and ideally to propose more appropriate surface structures than the existing ones. Therefore, it is intended to develop new processes for controlled surface modifications, and to develop new modelling tools for numeric analysis and understanding.
