Abstract

The article delves into the application of poly(3-dodecylthiophene)-grafted multi-walled carbon nanotubes (MWCNT-g-PDDT) as an additive to improve the charge transport properties of triple cation perovskite solar cells. By incorporating MWCNT-g-PDDT into the perovskite active layer, the study demonstrates significant enhancements in crystallinity, morphology, and photo-response. The research highlights that the grafted polymer helps disperse MWCNTs effectively, leading to dense, smooth, and uniform surfaces. This results in improved charge extraction, reduced charge transfer resistance, and lower recombination losses, ultimately enhancing the photovoltaic performance of the solar cells. The study emphasizes the potential of MWCNT-g-PDDT in achieving high-efficiency and stable perovskite solar cells, making it a valuable contribution to the field of renewable energy research.
