The development of a new generation of SWCNT/Si heterojunction solar cells has attracted great interest in research due to the extraordinary optoelectronic properties of single-walled carbon nanotube (SWCNT) materials. On the other hand, SWCNT has a weakness; namely, it is hydrophobic, so it is necessary to add hydrophilic functional groups to its surface so that it can be dispersed in organic solvents. In this study, we investigated the effect of functionalization treatment on SWCNT surfaces on solar cells performance. SWCNT is functioned by wet method using H2SO4 and HNO3 to form carboxylate groups along the SWCNT sidewalls. Characterization of samples using XRD to determine the F-SWCNT crystal phase and structure, SEM to characterized the morphology of the sample, FTIR to determine the functional group of the sample, and solar simulators to determine the efficiency of solar cells. Based on the solar simulator testing results, the power conversion efficiency increased significantly from 2.59% to 6.29% after functionalization treatment.
