Constructing Controlled Vertical Gradient Morphology in Pseudo-Planar Heterojunction Organic Photovoltaics via Self-Assembled Interface Orthogonal Strategy
{{output}}
Precisely regulating vertically distributed morphology by blade-coating process is crucial to realize high-performance large-scale pseudo-planar heterojunction organic photovoltaics (OPVs). However, the thermodynamic motion and random diffusion of donor/accept... ...
