Quantum dot solar cells.: Electrophoretic deposition of CdSe-C60 composite films and capture of photogenerated electrons with nC60 cluster shell

Encapsulation with a nC(60) cluster shell facilitates capture of photogenerated electrons from CdSe quantum dots following visible light extraction. Electrophoretic deposition of CdSe-C-60 composite clusters on optically transparent electrodes (OTE/SnO2) produce photoactive films that exhibit photochemical activity. The observed photoconversion efficiency (IPCE) of similar to 4% is significantly greater than those observed with CdSe or nC(60) films.
