In this study, the optical, morphological, and photovoltaic properties of CH3NH3PbI3 perovskite solar cells were investigated by embedding multi-walled carbon nanotubes grafted with poly(3-dodecylthiophene) (MWCNT-g-PDDT) and pure MWCNT into the active layer. It was found that the addition of 0.01% MWCNT-g-PDDT improved the photoresponse of the perovskite structure in the wavelength range of 400-800 nm. Field emission scanning electron microscopy revealed that the addition of 0.01% MWCNT-g-PDDT reduced pin-holes and empty spaces, while enhancing the J(sc) and PCE through a reduction in series resistance and improved charge transfer.
Multi-walled carbon nanotubes grafted with poly(3-dodecylthiophene) (MWCNT-g-PDDT) and pure MWCNT were embedded into the active layer to investigate the optical, morphological, and photovoltaic properties of CH3NH3PbI3 perovskite solar cells. Using an optimized concentration of MWCNT-g-PDDT (0.01%) improved photoresponse of perovskite structure in the wavelength range of 400-800 nm. Field emission scanning electron microscopy revealed that addition of 0.01% MWCNT-g-PDDT reduced the pin-holes and empty spaces. The grafted MWCNT enhanced the J(sc) as well as PCE by reduction in series resistance and impressive charge transfer from perovskite active layer to the contact transport layers.
