Abstract

The effects of MWCNT incorporation into non-vacuum chalcopyrite nanoparticle deposition solar cells were investigated in this study. To improve MWCNT dispersion within CuIn(S, Se)2 nanoparticle ink, MWCNT were grafted with maleic anhydride (MA) via plasma treatment. The functional groups on the surface of MWCNT were characterized by X-ray photoelectron spectroscopy. The grafting level of MA on MWCNT was 18.6 wt%. A series of CuIn(S, Se)2 nanoparticle solar cells with various weight ratios (wt%) of MWCNT-MA were fabricated. The structure of grounded CuIn(S, Se)2 nanoparticles was verified by transmission electron microscopy and X-ray diffraction analysis. The band gap energy of CuIn(S, Se)2 nanoparticles was obtained by UV–vis-NIR spectrophotometer. Scanning electronic microscopy showed that MWCNT–MA at ≤0.5 wt% dispersed well within CuIn(S, Se)2 nanoparticles. At 0.33 wt%, MWCNT-MA facilitated 15% increase in conversion efficiency of solution-based CuIn(S, Se)2 nanoparticle solar cells by increasing carrier transfer efficiency, and thus, increasing current density Jsc.
