“…Ultrafast pulse lasers, with a frequency pulse ranging from 10 -12 to 10 -15 s, are the most widely used systems for patterning graphene for electronic devices. This is because, compared to the removal of materials by conventional and lower-cost long-pulse laser treatment, these lasers minimize the diffusion of energy through the material, and therefore create smaller heat-affected zones [12] [13]. Although femtosecond lasers have been widely used to enhance the resolution of the scribe lines [14] [19], several studies have recently reported the patterning of graphene by means of nanosecond pulse lasers which offer a wider choice of wavelengths than femtosecond lasers.…”

This paper focuses on the development of patterned graphene/substrate by means of green nanosecond pulse laser irradiation. Monolayer graphene samples supported on a Si/SiO 2 substrate were patterned using 532 nm laser irradiation under fluence conditions ranging from 31 mJ/cm 2 and to 4240 mJ/cm 2. Raman spectroscopy was used to investigate the effect of laser irradiation on the graphene. It was found that at 356 mJ/cm 2 selective ablation of the graphene occurs. However, at fluence values above 1030 mJ/cm 2 (when damage to the substrate is observed) no ablation of the graphene takes place. In contrast, its graphenic structure was found to have been modified. Only at fluence values where the ablation of the substrate occurs, is graphene eliminated in an area almost equivalent to that of the ablated substrate. In this case, additional damage to the graphene sheet edges is produced. The increment in the number of oxygenated functional groups in these regions, as measured by XPS spectroscopy, suggests that this damage is probably caused by thermal phenomena during the ablation of the substrate.

Building‐integrated photovoltaics (BIPVs) stand as a promising solution to provide renewable electricity for achieving zero‐energy buildings, although still hindered from large‐scale implementations due to the difficulty of traditional photovoltaic modules in meeting the standards and aesthetics of architectural materials. The emergence of new photovoltaic materials and devices could pave the way for the future through offering diversity and tunability in colors and transparency along with comparable performance. Herein the recent advances in BIPVs are discussed, starting from an overview of various photovoltaic technologies regarding their material characteristics, state of the art, and adaptability to the built environment. The transparent and colored photovoltaic technologies are then respectively emphasized, concerning design principles, theoretical analysis, technical routes, and corresponding demonstration studies. The various strategies, including the materials and structures adopted to modify the transparency and color of solar cells, are highlighted. Finally, the challenges and future perspectives are addressed, followed by an outlook on factors that are critical for large‐scale implementation of BIPVs in the future.
