Metallization using reactive metal inks has recently attracted significant research interest due to its advantages in cost of materials and manufacturing, while still achieving performance comparable to traditional fire-through particle pastes. Here, we present for the first time the use of reactive silver (Ag) inks via industrial screen-printing and inkjet printing methods for the metallization of different Si surfaces used in tunneling oxide passivating contacts (TOPCon) and Silicon heterojunction (SHJ) solar cells.

III-V solar cells are highly efficient and reliable, however, they prove cost-prohibitive for many applications. Low-cost metallization strategies, such as screen-printing, represent a key opportunity to reduce cell costs, however conventional silver pastes are incompatible with III-V solar materials. Here we present two sets of III-V solar cells processed using a silver complex screen-printing ink: a set processed with screen-printed back contact and electroplated gold front contacts and a set processed with an electroplated gold back contact and screen-printed front contacts.

Organic light-emitting diodes (OLEDs) have great potential for use in large-Area display and lighting applications, but their widespread adoption for large areas is hindered by the high cost and insufficient performance of indium tin oxide (ITO) anodes. In this study, we introduce an alternative anode material a silver mesh embedded in glass-To facilitate production of large-Area OLEDs.

We present a simulation and experimental study of silver meshes to determine their performance for transparent electromagnetic interference (EMI) shielding. Simulations were employed to study the effects of the silver mesh’s width, pitch, and thickness on EMI shielding efficiency (SE) in the 8–18 GHz frequency range and transparency in the visible spectrum.

A facile and novel fabrication method is demonstrated for creating flexible poly(ethylene terephthalate) (PET)-embedded silver meshes using crack lithography, reactive ion etching (RIE), and reactive silver ink. The crack width and spacing in a waterborne acrylic emulsion polymer are controlled by the thickness of the polymer and the applied stress due to heating and evaporation.

Abstract Simulation and experimental studies are carried out on single‐layer and double‐layer embedded metal meshes (SLEMM and DLEMM) to assess their performance as transparent electromagnetic interference (EMI) shielding. The structures consist of silver meshes embedded in polyethylene terephthalate (PET). As a transparent electrode, SLEMMs exhibit a transparency of 82.7% and a sheet resistance of 0.61 Ωsq−1as well as 91.0% and 1.49 Ωsq−1. This performance corresponds to figures of merit of 3101 and 2620, respectively.

There is a major need to manufacture highly electrically conductive fabrics with stretch- and wash-durability. In this work, we provide both modeling and experiments of the mechanical failure of silver ink coatings on knitted fabric. Large thickness metal films are needed for high conductance but tend to debond from the underlying fabric microfibers that lead to cracking and failure.

In this paper, we demonstrate a highly conductive, stretchable, and wash-durable fabric for a variety of electronic textile applications such as electromagnetic interference (EMI) shielding, Joule heating, and strain sensing by utilizing a chemical etchant pretreatment that promotes covalent bonding, a reactive silver ink with conformal in situ silver reduction, and the use of a polymer coating for a protective barrier.
