Organic photovoltaics (OPVs) are compatible with printing processes. We show that inkjet printing technology can be used for the fabrication of high-efficiency OPVs. The appropriate selection of organic solvent mixture creates an ultrasmooth inkjet printed active layer with intimate morphology and interfaces for efficient performance (see figure). We report 3% power-conversion-efficiency organic solar cells with inkjet printed polymer: fullerene blend photoactive layer.
