“…Devices based on microelectromechanical systems (MEMS) are used in various applications, including electronics, information technology, biomedicine, and energy‐harvesting systems. As an alternative to the conventional photobeam/e‐beam‐/ion‐beam lithography techniques, laser direct structuring/writing (LDS/LDW) has attracted considerable interest as a simple, maskless, low‐cost method for fabricating 2D and 3D structures of different metals and their oxides . Recently, LPKF Laser & Electronics AG has demonstrated a precise and effective LDS method to produce microstructured layouts.…”

Recent technological advances in developing a diverse range of lasers have opened new avenues in material processing. Laser processing of materials involves their exposure to rapid and localized energy, which creates conditions of electronic and thermodynamic nonequilibrium. The laser-induced heat can be localized in space and time, enabling excellent control over the manipulation of materials. Metal oxides are of significant interest for applications ranging from microelectronics to medicine. Numerous studies have investigated the synthesis, manipulation, and patterning of metal oxide films and nanostructures. Besides providing a brief overview on the principles governing the laser-material interactions, here, the ongoing efforts in laser irradiation of metal oxide films and nanostructures for a variety of applications are reviewed. Latest advances in laser-assisted processing of metal oxides are summarized.

“…The same can be said about procedures developed in the organic photovoltaics (OPVs) field. Many recent developments to optimize laser processing of PV modules based on organic semiconductors have been reported in the literature, which should enable the high‐throughput manufacture of these thin‐film modules, whilst ensuring high geometrical aperture ratios . Inactive or dead areas as low as 200 μm have been reported, with module geometrical aperture ratios larger than 90–97%.…”

Dye‐sensitized and perovskite solar cells have seen tremendous efforts in their development in recent years. Amongst these developments are the design and implementation of fabrication techniques that can guarantee high performance as well as scalability over large areas. Laser processing has become a versatile and important tool in many industries and has also been applied successfully to both types of solar cell technologies, culminating in the demonstration of dye solar devices where all temperature treatments have been replaced with laser techniques, and of high‐performance solid‐state perovskite modules. Herein, we introduce concepts and review the available literature, pertaining to the effective utilization of laser beams for the development of both dye‐sensitized and perovskite photovoltaic technologies.

“…The on-the-fly method for synchronizing a laser galvanometer scanner and a linear stage for quick and wide area fabrication could be promising in this direction [ 130 ]. Moreover, the roll-to-roll technique [ 131 ] could be a good candidate, too, for helping laser processing to become an enabling technology for the manufacture of anti-icing surfaces at an industrial scale. However, no studies on large-scale laser texturing for anti-icing could be found in the literature.…”

In numerous fields such as aerospace, the environment, and energy supply, ice generation and accretion represent a severe issue. For this reason, numerous methods have been developed for ice formation to be delayed and/or to inhibit ice adhesion to the substrates. Among them, laser micro/nanostructuring of surfaces aiming to obtain superhydrophobic behavior has been taken as a starting point for engineering substrates with anti-icing properties. In this review article, the key concept of surface wettability and its relationship with anti-icing is discussed. Furthermore, a comprehensive overview of the laser strategies to obtain superhydrophobic surfaces with anti-icing behavior is provided, from direct laser writing (DLW) to laser-induced periodic surface structuring (LIPSS), and direct laser interference patterning (DLIP). Micro-/nano-texturing of several materials is reviewed, from aluminum alloys to polymeric substrates.
