An innovative hybrid QD sensitized photovoltaic carbon nanotubes microyarn has been developed using thermally-stable and highly conductive carbon nanotubes yarns (CNYs). These CNYs are highly inter-aligned, ultrastrong and flexible with excellent electrical conductivity, mechanical integrity and catalytic properties. The CNYs are coated with a QD-incorporated TiO2 microfilm and intertwined with a second set of CNYs as a counter electrode (CE). The maximum photon to current conversion efficiency (ηAM1.5) achieved with prolonged-time stability was 5.93%. These cells are capable of efficiently harvesting incident photons regardless of direction and generating photocurrents with high efficiency and operational stability.

Abstract

An innovative hybrid QD sensitized photovoltaic carbon nanotubes microyarn has been developed using thermally-stable and highly conductive carbon nanotubes yarns (CNYs). These CNYs are highly inter-aligned, ultrastrong and flexible with excellent electrical conductivity, mechanical integrity and catalytic properties. The CNYs are coated with a QD-incorporated TiO2 microfilm and intertwined with a second set of CNYs as a counter electrode (CE). The maximum photon to current conversion efficiency (ηAM1.5) achieved with prolonged-time stability was 5.93%. These cells are capable of efficiently harvesting incident photons regardless of direction and generating photocurrents with high efficiency and operational stability.
