Flexible perovskite solar cells (PSC) represent a viable technology for applications requiring high power-to-weight ratios, seamless integration onto a variety of shapes, and low embedded energy. Strategies to boost the performance of flexible PSC, which still lag behind their rigid counterparts, include passivation of the perovskite surface...

A miniaturized planar Yagi-Uda antenna for integration with PicoSats or other SmallSat missions is proposed. Miniaturization techniques, such as meandering and 1-D artificial dielectric concepts to reduce the guided wavelength, are employed to overcome space constraints imposed by the SmallSat footprint while still maintaining good performance...

Spatial atomic layer deposition (sALD) of p-type SnO is demonstrated using a novel liquid ALD precursor, tin(II)-bis(tert-amyloxide), Sn(TAA)2, and H2O as the coreactant in a process which shows an increased deposition rate when compared to conventional temporal ALD. Compared to previously reported temporal ALD chemistries for the deposition of...

An efficient substrate-configuration p-i-n metal-halide perovskite solar cell (PSC) is fabricated on a polymer-coated steel substrate. The optimized cell employs a Ti bottom electrode coated with a thin indium tin oxide (ITO) interlayer covered with a self-assembled [2-(9H-carbazol-9-yl)ethyl]phosphonic acid monolayer as a hole-selective contact...

In atomic layer deposition (ALD), thin layers of materials are deposited on a substrate with atomic layer precision in the vertical direction. The ability to control layer growth in the lateral direction as well is expected to greatly increase the potential of ALD as a path to the bottom-up additive fabrication of electronic devices like solar...

This study examines two strategies—homo- and heterogeneous approaches for the light-driven oxidation of benzyl alcohol in dye-sensitised photoelectrochemical cells (DSPECs). The DSPEC consists of a mesoporous anatase TiO2 film on FTO (fluorine-doped tin oxide), sensitised with the thienopyrroledione-based dye AP11 as the photoanode and an FTO–Pt...

A planar quasi-endfire surface-wave antenna (SWA) using substrate integrated waveguide (SIW) technology for integration with CubeSats and other small satellites is proposed in this letter. This antenna can be attached to the body of the satellite, resulting in a compact and low-cost design. A quasi-endfire beam pattern is achieved by the...

In this work, we report on the atomic layer deposition (ALD) of HfNx thin films by employing CpHf(NMe2)3 as the Hf(IV) precursor and Ar–H2 plasma in combination with external RF substrate biasing as the co-reactant. Following up on our previous results based on an H2 plasma and external RF substrate biasing, here we address the effect of ions...

The poor access to data on the marine environment is a handicap to government decision-making, a barrier to scientific understanding and an obstacle to economic growth. In this light, the European Commission initiated the European Marine Observation and Data Network (EMODnet) in 2009 to assemble and disseminate hitherto dispersed marine data. In...

The human body is exposed to many xenobiotic, potentially harmful compounds. The intestinal immune system is crucial in protecting the human body from these substances. Moreover, many microorganisms, residing in the gastrointestinal tract, play an important role in modulating immune responses. Pre- and probiotics may have beneficial effects on...

In this paper, an all-dielectric metasurface for surface enhanced Raman spectroscopy (SERS) is presented. The proposed design constitutes of an array of silicon (Si) dimers on top of thin film of silicon nitride (SiN), deposited on a glass substrate. The coupling mechanism between the dimers is based on two orthogonal guided waves in the SiN...

Plasma-enhanced atomic layer deposition (PEALD) has obtained a prominent position in the synthesis of nanoscale films with precise growth control. Apart from the well-established contribution of highly reactive neutral radicals towards film growth in PEALD, the ions generated by the plasma can also play a significant role. In this work, we...

In this paper we present elastomeric large-area arrays of pressure sensors based on printed electronics. Two applications are presented to demonstrate the versatility and scalability of the presented technology. The first consists of a shoe inlay with over 700 sensors (5 mm pitch) and the second consists of large-area sensor mat (30 cm × 40 cm)...

Atomic layer etching (ALE) provides Ångström-level control over material removal and holds potential for addressing the challenges in nanomanufacturing faced by conventional etching techniques. Recent research has led to the development of two main classes of ALE: ion-driven plasma processes yielding anisotropic (or directional) etch profiles...

The industrialization of perovskite solar cells (PSC) require processes to efficiently deposit the constituent layers over large areas. In this work we optimized the use of slot die coating process for both sheet-to-sheet (S2S) and roll-to-roll (R2R) manufacturing. Particular focus have been put on the control of the uniformity of perovskite...
