Quantum Dot Solar Cells. Electrophoretic Deposition of CdSe−C60 Composite Films and Capture of Photogenerated Electrons with nC60 Cluster Shell
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 approximately 4% is significantly greater than those observed with CdSe or nC60 films.
