Improved performance in flexible organic solar cells via optimization of highly transparent silver grid/graphene electrodes
Abstract
Organic solar cells (OSCs) were fabricated on polyethylene terephthalate (PET) substrates using hybrid silver grid/graphene films as transparent conducting electrodes and the effect of the silver grid dimensions was characterized. OSCs fabricated using optimized grid dimensions of 200 μm × 200 μm × 50 nm × 2 μm (length × width × height × linewidth) on PET substrates exhibited two times the power conversion efficiency of control devices using graphene only.
