Inkjet printing is a powerful and cost-effective technique for deposition of liquid inks with high accuracy, which is not only of great significance for graphic applications but also has enormous potentials for the direct printing of optoelectronic devices. This review highlights a comprehensive overview of the progresses have been made in optoelectronics fabrication by inkjet printing technique. The rst part briefly covers the droplet-generation process in nozzles of printheads and the physical properties affecting droplet formation and the profiles of the printed patterns. The second section outlines the recently activities related to applications of inkjet printing in optoelectronics fabrication including solar cells, light-emitting diodes, photodetectors and transparent electrodes. In each application field, challenges with inkjet printing process and the possible solutions are discussed before a few remarks. In the last section, a brief summary on the progress on inkjet printing fabrication of optoelectronics and an outlook for future research effort are presented.
