“…These solutions can then be deposited using standard lab‐based techniques such as spin coating, but also using sophisticated, technology‐relevant processing systems such as inkjet‐printing or roll‐coating . Organic field effect transistors (OFETs), highly efficient organic photovoltaics (OPVs) and high‐performance OLEDs, have been fabricated using inkjet printing, thereby underlining the versatility of this printing method …”

Through the use of solution‐based materials, the field of printed organic electronics has not only made new devices accessible, but also allows the process of manufacture to move toward a high throughput industrial scale. However, while solution‐based active layer materials in these systems have been studied quite intensely, the printed electrodes and specifically the transparent conductive anode have only relatively recently been investigated. In this progress report, the use of metal nanoparticles within printed organic electronic devices is highlighted, specifically their use as replacement of the commonly used indium tin oxide transparent conductive electrode within organic photovoltaics (OPVs) and organic light emitting diodes (OLEDs). A cross fertilization between the applications is expected since an OPV device is essentially an inversely operated OLED. This report aims to highlight the use of inkjet‐printed nanoparticles as cost‐effective electrodes for printed optoelectronic applications and discusses methods to improve the conductive and interfacial properties. Finally, in an outlook, the use of these types of metal nanoparticle inks to manipulate light management properties, such as outcoupling, in the device is investigated.

“…[12][13][14][15] Nowadays, silver nanoparticle-based inks are dominant in the field and several efficient ITO-free OPVs with IJP silver grids have been reported. [16][17][18][19][20][21][22] On the other hand, copper nanoparticle-based inks are gaining more and more attention, as copper nanoparticle ink is six times cheaper than silver nanoparticle ink and could potentially further reduce the fabrication cost of OPVs. [23] However, to our knowledge ITO-free printed electronic devices using Cu electrodes have not been previously reported in the literature.…”

Copper nanoparticle inks have drawn much attention since they have the potential to constitute an alternative cost‐effective solution than other noble metals nanoparticle inks such as Ag for indium tin oxide (ITO)‐free printed electronic applications. Our research and development efforts have produced high conductivity copper nanoparticle inks which have excellent jetting and printing properties resulting in high quality inkjet‐printed (IJP) Cu nanoparticle‐based metal grids. We present ITO‐free, Si‐PCPDTBT: PC[70]BM organic photovoltaics (OPVs) processed in ambient low‐cost fabrication conditions comprising for the first time embedded and non embedded inkjet‐printed copper grid/Poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) as the bottom electrode with power conversion efficiencies (PCE) of 2.56 and 3.35%, respectively. The results of the ITO‐free OPVs using inkjet‐printed Cu nanoparticle current collecting grids are discussed relevant to reference ITO‐based OPVs with PCE of 4.92%.

“…ITO films are mostly prepared by chemical vapor deposition [5], thermal evaporation [6], and DC and radio frequency magnetron sputtering [7], which require expensive vacuum systems and high temperatures not compatible with reel-to-reel processes [8]. To effectively take advantage of ambient processing, nonvacuum approaches for electrode fabrication are highly desirable [8,9]. Much progress has been achieved in recent years on producing ITO electrodes from solution [10][11][12].…”

The production of nanoparticles from solution typically involves the use of complex solution additives or particle functionalization with organic ligands to prevent aggregation. Another approach would be to produce the particles within a nanoscale environment, such as inside a micelle. In this contribution, we produced indium tin oxide nanoparticles using the diblock copolymer reverse micelle approach. We examined different solution precursor routes without any additives. Additionally, we examined the role of the reaction sequence, either nanoparticle formation outside the micelles or using the micelle itself as a nanoreactor. PACS Nos.: 72.20.Jv, 81.16.Dn, 82.33.Nq.Résumé : La production de nanoparticules en solution implique typiquement l'ajout d'additifs complexes à la solution ou une fonctionnalisation avec des ligands organiques pour prévenir l'agrégation. Une autre approche verrait la production de nanoparticules dans un environnement à l'échelle nano, comme à l'intérieur d'une micelle. Nous produisons ici des nanoparticules d'oxyde d'indium-étain en utilisant une approche de micelles inverses de copolymère bi-séquencé. Nous examinons différents précurseurs, avec et sans additifs. De plus, nous examinons la séquence de réaction, soit la formation de nanoparticules en dehors de la micelle, soit en utilisant la micelle elle-même comme nano-réacteur.
