Fabrication, characterization, and optical modeling of a new architecture for organic photovoltaics: The vertically orientated stack device

摘要

We introduce a new architecture for organic photovoltaics based on vertically orientated devices. The fabrication, device characteristics, and an optical model of the stack organic photovoltaic (OPV) device are presented. This new architecture gives rise to an alternative to the common flat-panel structure, which was originally conceived for the first silicon devices. The OPV stack device has an increased short circuit current density, fill factor, and power-conversion efficiency, as opposed to the standard flat-panel device.
