title: Device engineering for highly efficient top-illuminated organic solar cells with microcavity structures.
abstract: Small-molecule organic solar cells with microcavity structures utilizing very thin solar-absorbing active layers are simulated and fabricated. By carefully fine-tuning the in-cell spacer layer and out-of-cell capping layer, highly efficient top-illuminated indium tin oxide-free solar cells are created on glass and flexible polyethylene terephthalate substrates with efficiencies of up to 5.5% and 5%, respectively.
