Printing techniques for the fabrication of diodes have received increasing attention over the last decade due to their great potential as alternatives for high‐throughput and cost‐effective manufacturing approaches compatible with both flexible and rigid substrates. Here, the progress achieved and the challenges faced in the fabrication of printed diodes are discussed and highlighted, with a focus on the materials of significance (silicon, metal oxides, nanomaterials, and organics), the techniques utilized for ink deposition (gravure printing, screen printing, inkjet printing, aerosol jet printing, etc.), and the process through which the printed layers of diode are sintered after printing. Special attention is also given to the device applications within which the printed diodes have been successfully incorporated, particularly in the fields of rectification, light emission, energy harvesting, and displays. Considering the unmatched production scalability of printed diodes and their intrinsic suitability for flexible and wearable applications, significant improvement in performance and intensive research in development and applications of the printed diodes will continuously progress in the future.

“…Radio‐frequency identification device (RFID) is expected to play a key role in enabling identification technology in IOT . Different kinds of substrates have been applied to fabricate RFID tags, including polyethylene terephthalate, polyethylene naphthalate, polyimide (PI), and paper . Paper is not only widely available, inexpensive, and well established but also lightweight, biodegradable, and can be creased for storage in small spaces or made into 3D self‐standing structures; so it is an ideal flexible substrate for RFID tags.…”

A reliable and low-cost solution-processing procedure to synthesize a highly adhesive flexible metal antenna with low resistivity for radio-frequency identification device (RFID) tags on paper substrates via inkjet printing combined with surface modification and electroless deposition (ELD) is demonstrated in this paper. Through the surface modification of colloidal solution of hydrolyzed stannous chloride and chitosan solution, the paper-based substrate is able to reduce the penetration rate of ink and further increase the adsorption amount of silver ions, which could create a catalytic activating layer to catalyze the subsequent ELD of a conductive deposited metal antenna. The resulting metal antenna for RFID tags presents good adhesive strength and low resistivity of 2.58 × 10 −8 Ω·m after 40 min of ELD, and maintains a reliable reading range of RFID tags even after over 1000 times of bending and mechanical stress. Consequently, the developed technology proposed allows for cheap, efficient, and massive production of metal antenna for paper-based RFID tags with excellent mechanical and electrical properties. Furthermore, this process is especially advantageous for the fabrication of next-generation flexible electronic devices based on paper substrates.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201902579.identification technology in IOT. [2] Different kinds of substrates have been applied to fabricate RFID tags, including polyethylene terephthalate, [3][4][5] polyethylene naphthalate, [6][7][8] polyimide (PI), [9][10][11] and paper. [12,13] Paper is not only widely available, inexpensive, and well established but also lightweight, biodegradable, and can be creased for storage in small spaces or made into 3D self-standing structures; [14,15] so it is an ideal flexible substrate for RFID tags. Using paper as an insulating substrate, it is possible to fabricate RFID tags i) that do not need extra coarsening process because of enough surface roughness; [16] ii) that can naturally degrade; [17] iii) that is an abundantly available renewable material; [18] iv) that involves little absorption of electromagnetic energy due to its low dielectric constant and loss tangent angle. [19][20][21][22] Commercial paper-based RFID tags comprise metal antenna, integrated circuit (IC), and paper substrate, of which metal antenna accounts for 80% of the whole tag cost. [23] At present, the most mature method for preparing metal antenna RFID tag based on organic plastic substrate in industry is the subtractive etching method. [24] Although this traditional method of manufacturing metal antenna shows some superior characteristics, including high accuracy, low resistivity, and good weather resistance, it does generate some disadvantages such as high cost, restriction about substrate type, and environmental pollution. [20,25] In addition, the damage to fiber structure in paper substrate cannot be avoided due to the oxidation of fiber by the strong acid etching s...

“…In today's state-of-the-art of semiconductor technologies, organic semiconductors have both demonstrated their ability to achieve technological applications at the consumer-electronic market-level [1,2], and continues to inspire the scientific community by unlocking truly disruptive abilities to realize next-generation electronics [3][4][5]. For their potentials for lowcost electronics [6], soft processing, and device added features such as flexibility or transparency [7], these materials have been widely investigated in a range of microelectronic and optoelectronic architectures such as field-effect transistors [8], light-emitting PN-diodes (OLEDs) [9], Schottky diodes [10] and single carrier sensing devices [11]. In any of these applications, significant improvements in the electrical performances [12][13][14] can be achieved by means of molecular doping (i.e., chemical doping by incorporating highly electronaccepting/donating molecules into the organic semiconductor).…”

Simultaneously optimizing performances, processability and fabrication cost of organic electronic materials is the continual source of compromise hindering the development of disruptive applications. In this work, we identified a strategy to achieve record conductivity values of one of the most benchmarked semiconducting polymers by doping with an entirely solution-processed, water-free and cost-effective technique. High electrical conductivity for poly(3-hexylthiophene) up to 21 S/cm has been achieved, using a commercially available electron acceptor as both a Lewis acid and an oxidizing agent. While we managed water-free solution-processing a three-time higher conductivity for P3HT with a very affordable/available chemical, near-field microscopy reveals the existence of concentrationdependent higher-conductivity micro-domains for which furthermore process optimization might access to even higher performances. In the perpetual quest of reaching higher performances for organic electronics, this work shall greatly unlock applications maturation requiring higher-scale processability and lower fabrication costs concomitant of higher performances and new functionalities, in the current context where understanding the doping mechanism of such class of materials remains of the greatest interest.
