Highly efficient silicon-based solar cells employing nanostructured layers

Much effort is currently being devoted by the photovoltaic industry in order to decrease the cost of solar electricity. Such a cost reduction may be obtained either by reducing the material and process costs or by improving of the efficiency of the solar cells. This project follows the latter approach, and aims at developing technology for making highly efficient silicon-based solar cells employing nanostructured layers.

An advanced technology for reducing losses caused by interface recombination, which is compatible with the conventional technology for silicon-based solar cell processing will be developed. Ultra-thin layers of amorphous hydrogenated silicon or silicon carbide will be incorporated into the solar cell structure in order to reduce the interface recombination. In parallel, technology for employing transparent conductive oxide layers in combination with the ultra-thin films will be developed.

This project is a KMB-project funded by the Norwegian Research Council, and is performed in collaboration with the University of Oslo and Renewable Energy Corporation. Project ended in mid 2008.
