Abstract

Abstract : Single-walled carbon nanotubes can help charge extraction in mesoscopic CH3 NH3 PbI3 -based perovskite solar cells using TiO2 /Al2 O3 /carbon as a scaffold. Abstract : A single walled carbon nanotube (SWCNT) possesses excellent hole conductivity. This work communicates an investigation of perovskite solar cells using a mesoscopic TiO2 /Al2 O3 structure as a framework in combination with a certain amount of SWCNT-doped graphite/carbon black counter electrode material. The CH3 NH3 PbI3 -based device achieves a power conversion efficiency of 14.7% under AM 1.5G illumination. Detailed investigations show an increased charge collection in this device compared to that without the SWCNT additive.
