Carbon nanotubes for organic/inorganic hybrid solar cells

This article describes the material properties and thin film forming strategies for carbon nanotubes. It summarizes the developments and the challenges related to doping and reviews the highlights over the past decade about organic/inorganic hybrid solar cells using carbon nanotubes (CNTs) CNTs. Replacing the indium tin oxide electrode by CNT spiderwebs have displayed solar cell efficiencies of about 3-4% for organic bulk heterojunction devices, enabling a cost effective fabrication of organic solar cells by roll-toroll process. Investigations on SWNT/Si hybrid solar cells with efficiency of 17% demonstrate the possibility of wide range applications of SWNTs in organic/inorganic hybrid solar cells. (C) 2015 Elsevier Ltd.
