“…This is not unexpected considering the advantages of paper as a highly versatile and commonly employed material that combines low-cost and excellent environmental compatibility [20]. Furthermore, the physical and chemical properties of this superb printing substrate (e.g., topography, roughness, stiffness, surface energy, polarity, porosity and pore geometry) can be easily tailored by means of diverse coating materials and techniques as well as by surface treatments according to the specific needs of the envisioned applications [21–24].…”

SummaryInkjet printing of spherical gold nanoparticles is widely applied in the fabrication of analytical and diagnostics tools. These methods could be extended to non-spherical gold nanoparticles that can efficiently release heat locally when irradiated in the near infrared (NIR) wavelength region, due to localized surface plasmon resonance (LSPR). However, this promising application requires the ability to maintain high efficiency and tunability of the NIR LSPR of the printed nanoparticles. In this study stable inks containing PEGylated gold nanostars (GNS) were fabricated and successfully inkjet-printed onto differently coated paper substrates with different porosity and permeability. A pronounced photothermal effect was observed under NIR excitation of LSPR of the printed GNS patterns even at low laser intensities. It was found that beside the direct role of the laser intensity, this effect depends appreciably on the printing parameters, such as drop density (δ, drops/mm2) and number of printed layers, and, critically, on the permeability of the coated paper substrates. These results will promote the development of GNS-based printed platforms for local photothermal therapy.

“…Note that in contrast, Table 1 does not suggest any migration and concentration of Ca 2+ . It has been shown previously that the physical structure of paper coatings has a profound influence of the film formation and the resulting conductivity of inkjet-printed metal NP films 26,27 . It was proposed that surface roughness and pore size distribution are critical parameters for the conductive film formation.…”

Inkjet-printed metal films are important within the emerging field of printed electronics. For large-scale manufacturing, low-cost flexible substrates and low temperature sintering is desired. Tailored coated substrates are interesting for roll-to-roll fabrication of printed electronics, since a suitable tailoring of the ink-substrate system may reduce, or remove, the need for explicit sintering. Here we utilize specially designed coated papers, containing chloride as an active sintering agent. The built-in sintering agent greatly assists low-temperature sintering of inkjet-printed AgNP films. Further, we examine the effect of variations in coating pore size and precoating type. Interestingly, we find that the sintering is substantially affected by these parameters. IntroductionThe interest in printed electronics and other printed functionalities is considerable worldwide. In contrast to traditional subtractive photolithography-and etching processes, the printing process is purely additive, which means less material waste and a reduced need for processing chemicals. This results in cost savings and environmental advantages, in particular when large area coverage is desired. Additionally, printing processes have good compatibility with flexible substrates such as plastic films and paper. Applying electronic-or other functionality on flexible, low-cost substrates, across large areas in roll-to-roll processes, enables novel applications with large potential. Among the many important applications for printed electronics are photovoltaic devices . It is capable of covering large areas with simple and cost-effective setups. Furthermore, the non-contact nature of deposition allows it to be used for delicate and pressure-sensitive surfaces. The ink formulation is relatively challenging. To be reliably jetted, properties such as viscosity, surface tension, volatility and particle size need to be well controlled. To avoid aggregation, the particles are typically stabilized using polymers that adhere to the surfaces. Depending on the specific polymers and electrical charges in the system, the stabilization may be either steric, electrostatic or a combination of both (electrosteric) 13 . Some of the most common stabilizing polymers are polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA) 14 .Electrically conducting layers are important since they are included in most applications of printed electronics. Although conductive inkjet inks may be formulated from several classes of materials, including conductive polymers 15 , carbon-based materials 16,17 , and metal nanoparticles (NPs) [18][19][20] . The metal NP inks are particularly suitable when high conductivity is required, for example when printing antennas 21 and circuit board conductors 22,23 .Paper-based substrates for printed electronics are interesting for several reasons. Environmental friendliness, flexibility and low cost are the key benefits. The physical and chemical properties may be altered by chemical additives or changes in materials and processes.

“…Such surfaces represent a challenge for uniform thin‐film deposition. There are ways to overcome this drawback, such as smoothing the paper surface by coating followed by supercalendaring or even more effective cast‐coating a layer, which gives it a smooth finishing . Smoothing the paper surface can make it suitable to uniform thin‐film coating by physical vapour deposition (PVD) and chemical vapour deposition (CVD) technologies.…”

Cellulose substrates for PV applications present a fibrous surface texture that is not suitable for the uniform deposition of thin‐film solar cells causing poor device performance. However, uniform thin‐film deposition and efficient light management for solar cells can be achieved on cellulose substrates by transferring well‐known surface textures that provide an adequate surface for thin film solar cell deposition and also, provide light scattering properties into the cellulose surface. In this work, we study the properties of crater‐like textures transferred onto cellulose substrates by nanoimprint lithography and the corresponding effect on the J–V and EQE characteristics of amorphous silicon thin‐film solar cells. The prototype solar cells are deposited on cellulose substrates and the results are compared with the results of such solar cells deposited on flat glass substrates. The results show that the J–V characteristics of solar cells deposited on planar as well as textured glass substrates are well reproduced. Due to the process routine, the solar cells on the cellulose substrate with nanoimprinted textures show an increase in the short circuit current density and power conversion efficiency over previous results in our laboratory.
