PV parameters of best performing PSC devices fabricated based on TiO₂ NF photoelectrodes with different SWCNT loadings (extracted from the J–V characteristics reported in Figure 4). The average PCEs were calculated based on at least five devices. PV parameters of the best devices are highlighted in bold
