Dry plasma synthesis of a MWNT–Pt nanohybrid as an efficient and low-cost counter electrode material for dye-sensitized solar cells

Abstract

Dry plasma reduction (DPR) is an excellent approach for easily and uniformly immobilizing many platinum nanoparticles (Pt-NPs) with a size of 2–3 nm on both inner and outer surfaces of MWNTs under atmospheric pressure and at near room temperature. The MWNT–Pt nanohybrid exhibits quite low charge transfer resistance for dye-sensitized solar cells.
