Polymer Quantum Dot-Sensitized Solar Cell Incorporating Single-Walled Carbon Nanotubes

Abstract

Regioregular poly(3-hexylthiophene) (P3HT) of conjugated polymer is known to be p-type hole transports material. P3HT is used as a material to substitute for the liquid electrolyte in the quantum dot-sensitized solar cells (QDSSCs). In order to gain high performance of the cell, three different cells using P3HT, pristine P3HT, single-walled carbon nanotube (SWNT)-mixed P3HT (mixing), and SWNT-blended P3HT (blended) are made and their photovoltaic cells measure J-V curve, incident photon to current efficiency, and electrochemical impedance spectroscopy. Those values obtained from experiments are compared with each other.
