Table 2.

PV characteristics of different DSSCs fabricated under various conditions. Graphene, modified Hummers method132 and hydrazine are abbreviated as “G”, “MH method” and “hyd”, respectively. The abbreviation of “↑↑” and “↓” in the dye adsorption column represents the amount of adsorbed dye in the rGO/TiO₂ film “increased” and “decreased”, respectively, as compared to TiO₂‐only film
