Inkjet-printing of indium tin oxide (ITO) films for transparent conducting electrodes

Polymer assisted solution processing of Ti-doped indium oxide transparent conducting thin films for organic solar cells

“…The absorption coefficient (a) of the PAS-coated TIO films was calculated from the optical transmittance (T) and reflectance (R) data. The optical bandgap for the direct transition of electrons from the valence band to conduction band was related to the absorption coefficient (a) of the PAS-coated TIO film by the following equations [31]:…”

Additive Manufacturing of Materials: Viable Techniques, Metals, Advances, Advantages, and Applications

“…The range of materials for printed electronics produced by direct-writing techniques is growing rapidly, and the material list includes organic/inorganic semiconductors, biomaterials, conductive nanoparticles and polymers, dielectrics, ferromagnetic materials, and superconductors. [41][42][43][44][45][46][47][48][49][50] Additive digital printing offers new possibilities for conformal integration of active and passive devices meeting the manufacturing technology demands of higher functionality and improved energy efficiency over existing technologies. Printed electronics show promise for use in a wide range of discrete and integrated electronic device applications, such as thin-film transistors, organic light-emitting diode (OLED) lighting, solar cells, radiofrequency identification (RFID), antennas, inductors, capacitors, interconnects, sensors, and displays.…”

Overview of Semiconducting Conjugated Polymers

“…Silver is one of the most conductive elements and stable silver suspensions have already been reported in literature. By printing a silver mesh structure is sandwiched between inkjet printed ITO layers, the sheet resistance was reduced to 3.4 Ohms/square [59]. The silver mesh will provide the conductive pathways while the ITO will ensure work function match for better device performances.…”
