“…Laser-structured PET clearly has the ability to improve the efficiency of solar cells by utilising light scattering mechanisms. The increased haze is comparable to many high haze films that have been demonstrated to increase some cell efficiencies by over 10% [33][34][35][36]. The advantages in the process described in this paper have already been discussed somewhat in the introduction; however, they bear repeating when combined with the discoveries within this work.…”

Highly light scattering structures have been generated in a poly(ethylene terephthalate) (PET) film using a CO2 laser. The haze, and in some cases the transparency, of the PET films have been improved by varying the processing parameters of the laser (namely, scanning velocity, laser output power, and spacing between processed tracks). When compared with the unprocessed PET, the haze has improved from an average value of 3.26% to a peak of 55.42%, which equates to an absolute improvement of 52.16% or a 17-fold increase. In addition to the optical properties, the surfaces have been characterised using optical microscopy and mapped with an optical profilometer. Key surface parameters that equate to the amount and structure of surface roughness and features have been analysed. The CO2 laser generates microstructures at high speed, without affecting the bulk properties of the material, and is inherently a chemical-free process making it particularly applicable for use in industry, fitting well with the high-throughput, roll to roll processes associated with the production of flexible organic photovoltaic devices.

“…3,4 In order to obtain textured TCO thin lms, two approaches, including the employment of controlled micro-/nano-structures and pre-/post-deposition chemical etching, are mainly investigated. 5,6 The latter is actually less favourable to be used since the additional process would increase the manufacturing cost considerably, and thus the deposition of naturally textured TCO coatings has attracted greater attention. A proven example is the growth of transparent conductive B-doped ZnO lms with random pyramidal texture by means of low pressure chemical vapour deposition (LPCVD), which has already been successfully employed in commercial silicon solar modules.…”

“…So far, there exist several methods for surface texturing, including chemical, thermal, mechanical, and more recently hybrid processes like SACE as discussed above. A multi-step chemical surface modification was explored by Liu et al [127] that enhanced the light scattering potential of glass substrates used for solar cells. Glass surface was first micro-textured using frosting etching method through several steps of cleaning, frosting, and polishing with certain materials.…”

Brittle non-conductive materials, like glass and ceramics, are becoming ever more significant with the rising demand for fabricating micro-devices with special micro-features. Spark-Assisted Chemical Engraving (SACE), a novel micromachining technology, has offered good machining capabilities for glass and ceramic materials in basic machining operations like drilling, milling, cutting, die sinking, and others. This paper presents a review about SACE technology. It highlights the process fundamentals of operation and the key machining parameters that control it which are mainly related to the electrolyte, tool-electrode, and machining voltage. It provides information about the gas film that forms around the tool during the process and the parameters that enhance its stability, which play a key role in enhancing the machining outcome. This work also presents the capabilities and limitations of SACE through comparing it with other existing micro-drilling and micromachining technologies. Information was collected regarding micro-channel machining capabilities for SACE and other techniques that fall under four major glass micromachining categories—mainly thermal, chemical, mechanical, and hybrid. Based on this, a figure that presents the capabilities of such technologies from the perspective of the machining speed (lateral) and resulting micro-channel geometry (aspect ratio) was plotted. For both drilling and micro-channel machining, SACE showed to be a promising technique compared to others as it requires relatively cheap set-up, results in high aspect ratio structures (above 10), and takes a relatively short machining time. This technique shows its suitability for rapid prototyping of glass micro-parts and devices. The paper also addresses the topic of surface functionalization, specifically the surface texturing done during SACE and other glass micromachining technologies. Through tuning machining parameters, like the electrolyte viscosity, tool–substrate gap, tool travel speed, and machining voltage, SACE shows a promising and unique potential in controlling the surface properties and surface texture while machining.
