Quantum Dot Solar Cells. Electrophoretic Deposition of CdSe−C60 Composite Films and Capture of Photogenerated Electrons with nC60 Cluster Shell

Abstract

Encapsulation with a nC₆₀ cluster shell facilitates capture of photogenerated electrons from CdSe quantum dots following visible light excitation. Electrophoretic deposition of CdSe−C₆₀ composite clusters on optically transparent electrodes (OTE/SnO₂) produce photoactive films that exhibit photoelectrochemical activity. The observed photoconversion efficiency (IPCE) of ∼4% is significantly greater than those observed with CdSe or nC₆₀ films.
