a Illustration of the reverse bias current J s and energetic barrier ϕ in polymer/TiO2 HSCs. b Dependences of V oc and J S, in TiO2-NRA- (1), TiO2-NRA@TiO2-QD- (2), and TiO2-NRA@TiO2-QDs@N719-based (3) solar cells. E c and E v indicate conduction and valence band of TiO2, respectively; E LUMO and E HOMO indicate the highest occupied molecular orbital and lowest unoccupied molecular orbital of the polymer energy level, respectively
