Highly Efficient Organic Photovoltaic Cells from Polymer-Aligned Carbon Nanotube Dispersed Heterojunctions
Abstract
As we proposed originally, we have focused on the syntheses of novel vertically-aligned carbon nanotube arrays and conjugated macromolecules for photovoltaic cells. Towards this effort we have developed new synthetic methods for the growth of vertically-aligned single-walled carbon nanotubes (VA-SWNTs), semiconducting VA-SWNTs, and muiltcomponent micropatterns of VACNTs. We also designed and synthesized several classes of novel low bandgap photovoltaic active polymers, and polymer-/TiO2-coated VA-CNTs, critical to developing high efficient polymer photovoltaic cells and dye-sensitized solar cells. Polymer photovoltaic cells with 3-D structural features, including bilayer-/homotropically-aligned bulk-heterojunctions, were also developed for an efficient solar absorption and charge separation/collection. Besides, novel N-doped CNT fuel cells, polymer/quantum dot light-emitting diodes, and even CNT Gecko-foot-mimetic dry adhesives, were developed for energy management. This project has led to about 30 journal publications, including two Science and one Nature Nanotechnology papers, and a joint patent application with Wright-Patterson Air Force Base.
