Controlled Assembly of Hybrid Bulk-Heterojunction Solar Cells bySequential Deposition

This work presents a technique to create ordered and easily characterized hybrid nanocrystal-polymer composites by sequential deposition of tetrapod-shaped cadmium telluride (CdTe) nanocrystals and poly(3-hexlythiophene). With controlled fabrication and composite morphology, these devices offer several advantages over traditional codeposited hybrid cells, and provide a model system for detailed investigation into the operation of bulk-heterojunction cells
