Dithiol-capped Cdse nanoparticle Fims prepared by a soft chemistry method.

Abstract

Bulk heterojunction solar cells require adequuate concentrations of the nanoparticulated n-type semiconductor within the polymeric matrix, but also a good interfacial interaction between the. Thiol and dithiol molecules have been devised as good candidates to provide interaction betwen the components as well as electrical conduction by tunnel effect, with the advantage of polar heads that would increase nanoparticle-nanoparticles structuring in a tridimensional net.
