Photovoltaic cells based on dye-sensitisation of single-wall carbon nanotubes in a polymer matrix

摘要

A molecular dispersed heterojunction solar cell consisting of a polymer and dye coated carbon nanotubes blend sandwiched between metal electrodes has been developed. The dye naphthalocyanine (NaPc) was used as the main sensitiser, while nanotubes and poly(3-octylthiophene) (P3OT) act as the electron acceptor and the electron donor, respectively. The incorporation of the NaPc in the P3OT/SWNT composite does dramatically increase the layer absorption resulting in a much higher photocurrent. We report on the exploration of new principles and concepts to develop molecular electronic devices for low cost solar cells. (C) 2003 Elsevier B.V. All rights reserved. References: 11
