Organic semiconductor materials for improving solar cell performance

Summary

Organic solar cells are photovoltaic devices made from carbon-based polymers and are great potential sources of renewable energy. While they currently do not reach the same efficiency as silicon solar cells, they have the benefit of being cheaper to manufacture, lighter weight, and can form bendable components. This technology describes a new structure of an organic semiconductor material which can improve the efficiency of organic solar cells. Rather than the typical fullerene-based materials, the use of perylene diimides (PDI) arranged into graphene nanoribbons in this technology improves the conversion efficiency of organic solar cells, although the PDI can additionally be used for other applications such as electroluminescent devices or field effect transistors.
