Received: 22 October 2018; Accepted: 29 November 2018; Published: 4 December 2018 Abstract: The generation of electrical energy depending on renewable sources is rapidly growing and gaining serious attention due to its green sustainability. With fewer adverse impacts on the environment, the sun is considered as a nearly infinite source of renewable energy in the production of electrical energy using photovoltaic devices. On the other end, organic photovoltaic (OPV) is the class of solar cells that offers several advantages such as mechanical flexibility, solution processability, environmental friendliness, and being lightweight. In this research, we demonstrate the manufacturing route for printed OPV device arrays based on conventional architecture and using inkjet printing technology over an industrial platform. Inkjet technology is presently considered to be one of the most matured digital manufacturing technologies because it offers inherent additive nature and last stage customization flexibility (if the main goal is to obtain custom design devices). -

HP Inkjet Technology
HP inkjet technology The value of HP inkjet print cartridges and their reliability Innovative design HP ink is complex to design, with many variables that must be tested and optimized. During a typical ink design cycle, HP evaluates many hundreds of ink variations, with 50 to 80 different performance attributes measured for each variation. HP designs the ink, print cartridge, printer, and media in parallel as part of an iterative process. As ink formulas are created, HP conducts exhaustive tests to help fine- tune each of the components to work optimally together. For extremely realistic and reliable photo images, HP uses a color layering process precisely tuned for HP ink and paper. Any changes in the ink formulation could affect the reliability of the system as well as the quality of the printed output. HP thermal inkjet printing relies on genuine HP ink within the print cartridge to work optimally. During the printing process, tiny ink drops—as small as 4-picoliters—are launched through hundreds of printhead nozzles onto the paper. A picoliter is a millionth of a millionth of a liter! Inks contaminated with impurities or with different characteristics can cause problems within the ink cartridge, which is why HP goes to great lengths to ensure its inks always meet the correct formulation. To produce each color dot, HP accurately places as many as 32 tiny drops of ink onto the page. If HP ink is not used, ink drops can eject too quickly, or too slowly, affecting the quality of the print. PAGE 1 Excellence in manufacturing Chemists monitor many factors critical to HP’s ink quality during the manufacturing process. -

Low Temperature Chemical Sintering of Inkjet-Printed Zn Nanoparticles for Highly Conductive Flexible Electronic Components
www.nature.com/npjflexelectron ARTICLE OPEN Low temperature chemical sintering of inkjet-printed Zn nanoparticles for highly conductive flexible electronic components ✉ Subimal Majee 1 , Mikael C. F. Karlsson1,2, Anurak Sawatdee1, Mohammad Yusuf Mulla1, Naveed ul Hassan Alvi1, Valerio Beni1 and ✉ David Nilsson 1 This study illustrates an innovative way to fabricate inkjet-printed tracks by sequential printing of Zn nanoparticle ink and curing ink for low temperature in situ chemical sintering. Employing chemical curing in place of standard sintering methods leads to the advantages of using flexible substrates that may not withstand the high thermal budgets of the standard methods. A general formulation engineering method is adopted to produce highly concentrated Zn ink which is cured by inkjet printing an over-layer of aqueous acetic acid which is the curing agent. The experimental results reveal that a narrow window of acid concentration of curing ink plays a crucial role in determining the electrical properties of the printed Zn nanoparticles. Highly conductive (~105 S m−1) and mechanically flexible printed Zn features are achieved. In addition, from systematic material characterization, we obtain an understanding of the curing mechanism. Finally, a touch sensor circuit is demonstrated involving all-Zn printed conductive tracks. npj Flexible Electronics (2021) 5:14 ; https://doi.org/10.1038/s41528-021-00111-1 1234567890():,; INTRODUCTION Although non-metallic inkjet printable conductive inks are Inkjet-printing of electrodes and connectors using conductive inks available based on conductive polymers such as PEDOT:PSS, and has captured much attention in the last couple of decades in carbonaceous NPs (i.e., graphene); the majority of the conducting 2,7–13 various printed electronics applications owing to its non- inks available in the market rely on metallic NPs (Ag, Au, Cu, Ni) . -
Inkjet-Printed Light-Emitting Devices: Applying Inkjet Microfabrication to Multilayer Electronics
Inkjet-Printed Light-Emitting Devices: Applying Inkjet Microfabrication to Multilayer Electronics by Peter D. Angelo A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Chemical Engineering & Applied Chemistry University of Toronto Copyright by Peter David Angelo 2013 Inkjet-Printed Light-Emitting Devices: Applying Inkjet Microfabrication to Multilayer Electronics Peter D. Angelo Doctor of Philosophy Department of Chemical Engineering & Applied Chemistry University of Toronto 2013 Abstract This work presents a novel means of producing thin-film light-emitting devices, functioning according to the principle of electroluminescence, using an inkjet printing technique. This study represents the first report of a light-emitting device deposited completely by inkjet printing. An electroluminescent species, doped zinc sulfide, was incorporated into a polymeric matrix and deposited by piezoelectric inkjet printing. The layer was printed over other printed layers including electrodes composed of the conductive polymer poly(3,4-ethylenedioxythiophene), doped with poly(styrenesulfonate) (PEDOT:PSS) and single-walled carbon nanotubes, and in certain device structures, an insulating species, barium titanate, in an insulating polymer binder. The materials used were all suitable for deposition and curing at low to moderate (<150°C) temperatures and atmospheric pressure, allowing for the use of polymers or paper as supportive substrates for the devices, and greatly facilitating the fabrication process. ii The deposition of a completely inkjet-printed light-emitting device has hitherto been unreported. When ZnS has been used as the emitter, solution-processed layers have been prepared by spin- coating, and never by inkjet printing. Furthermore, the utilization of the low-temperature- processed PEDOT:PSS/nanotube composite for both electrodes has not yet been reported. -
Zinc Oxide Nanoparticles: Doping, Inkjet Printing, and Electron Accepting from Photoexcited Porphyrin Dyes
Zinc Oxide Nanoparticles: Doping, Inkjet Printing, and Electron Accepting from Photoexcited Porphyrin Dyes A DISSERTATION SUBMITTED TO THE FACULTY OF THE GRADUATE SCHOOL OF THE UNIVERSITY OF MINNESOTA BY Andrew Joseph Bierbaum IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Wayne L. Gladfelter June 2013 © Andrew Bierbaum 2013 Abstract This research attempted to extend the useful applications of ZnO by investigating ZnO nanoparticles, doping ZnO nanoparticles, characterizing electron injection from dye molecules into ZnO nanoparticles, and depositing thin films of doped ZnO nanoparticles using inkjet printing. Chapter 1 describes research that produced particles ranging from 2.7 nm to 1 µm of undoped and doped ZnO. These particles were made using solution methods with zinc acetate and aluminum and gallium nitrate salts as dopants, and the particles were characterized by ultraviolet visible absorption, photoluminescence, infrared absorption, and transmission or scanning electron microscopy. The doped ZnO nanoparticles displayed optical signatures of doping in particles larger than 10 nm. This is significant because doping of nanoparticles is still not fully understood, and there are few examples of successfully doping nanoparticles. Chapter 2 describes the research done toward inkjet printing of ZnO films for potential use in a fully inkjet printed solar cell. The research aim was to produce a TCO film of ZnO using inkjet printing that had a bulk resistivity between 10-2 and10-3 Ω cm, a thickness between 0.1 and 1 μm, the highest transparency possible, and processed using conditions under 250 ºC. Film produced using solution methods including inkjet printing were characterized by four point probe ohmmeter, x-ray diffraction, ultraviolet visible absorption, visible microscopy, profilometry, and scanning electron microscopy. -

Moiré-Fringeless Transparent Conductive Films with a Random
www.nature.com/scientificreports OPEN Moiré-fringeless Transparent Conductive Films with a Random Serpentine Network of Medium- Received: 1 March 2019 Accepted: 24 July 2019 Field Electrospun, Chemically Published: xx xx xxxx Annealed Silver Microfbres Dong-Youn Shin1, Eun-Hye Park1 & Ka-Hyun Kim2 Low-cost fexible transparent conductive flms (TCFs) with direct writing of metal grids have been explored as a promising alternative to conventional indium-tin-oxide-based TCFs for future fexible electronics. However, fexible TCFs have raised technical concerns because of their disadvantages, such as low resolution, low productivity, poor optoelectrical performance, poor thermal stability, and adverse moiré fringes, which primarily arise from the superposition of periodic patterns. Herein, a facile and highly productive method to fabricate moiré-fringeless TCFs with good optoelectrical characteristics and excellent thermal stability is presented using a single-pass printed random serpentine network of medium-feld electrospun silver microfbres (AgMFs) with a line width of 2.32 ± 0.97 μm by exploiting the random serpentine motion of medium-feld electrospinning, enabling moiré-fringeless TCFs. The electrical in-plane anisotropy of the TCFs can be kept well below 110.44 ± 1.26% with the in situ junction formation of the AgMFs in the transverse direction. Combined thermal and chemical annealing of the AgMFs enables high productivity by reducing the thermal annealing time by 40%. The good optoelectrical performance, fair electrical in-plane anisotropy, high productivity, and superior thermal stability of the TCFs with the single-pass printed random serpentine network of medium-feld electrospun AgMFs are suitable properties for fexible electronics such as ultra- large digital signage with LEDs.
