“…After the MCEE process, the PEDOT:PSS/flexible bSi on planar and textured PI substrates illustrates lower reflection over 300–1100 nm spectral region (with reflection of 7.7% at 600 nm wavelength) when compared to the PEDOT:PSS/flexible cSi on both planar and textured PI substrates. The reduced broadband reflection is due to the presence of the NWs on the wafer surface which reduces interfacial reflection on the front surface and improves the broadband light coupling and absorption in the wafer [ 6 , 20 ]. The R w for the PEDOT:PSS/flexible bSi on the planar PI is 8.33%.…”

“…The enhanced broadband absorption is attributed to presence of the random nanotextures (usually in the form of nanowires or nanopores) on the front surface of the silicon wafers with a gradually increasing refractive index which reduces broadband light reflection and improves light-coupling into the silicon absorber [ 3 , 4 , 5 ]. To produce flexible bSi surface, metal-catalyzed electroless etching (MCEE) technique is commonly applied to flexible silicon wafers due to its low-cost and facile fabrication process [ 6 , 7 , 8 ].…”

“…[67,89] Therefore, opaque SCs are often adjusted for near-complete absorption of visible light and appear as monotone dark or even black. [90] By manipulating the material design and the device architecture, colorful opaque and semitransparent SCs with a wide range of colors can be realized through internal or external spectral engineering approaches. The external strategies rely on the implementation of additional external coloring structures either on the front or on the back side of the basic PV device.…”

solar, wind, hydro, geothermal, and biomass, to enable a steady mitigation of greenhouse gas emissions, which are causing the planetary climate change and global warming. [5][6][7] Additionally, due to the economic development and the worldwide urbanization, a continuous rise of the global energy consumption across all key sectors, that is, power, heating, industry, and transport is occurring. This is expressed by an increase in the annual global electricity demand by 4.5% in 2021 corresponding to additional 1000 TWh. [4] Hence, strict criteria for the selection of competitive and abundant energy alternatives are imposed, requiring high yield at affordable prices. [8] The share of total renewables power generation excluding hydropower exceeded 3000 TWh in 2020, corresponding to almost 12% of the global electricity generation. [3] Considering an effective synergy between various sustainable energy candidates, solar photovoltaics (PV) have demonstrated great capabilities that can satisfy the requirements in the pathway towards 100% renewable electricity. [9][10][11][12] Owing to the research and development activities over the last decades, the power conversion efficiencies of solar cells (SC) have skyrocketed with a prolonged operation lifetime (>15 years) and a drastic plummeting in manufacturing costs (global average module selling price below $0.25 per W). [6,[13][14][15] The rapid universal deployment of PV resulted in a contribution of about 3.4% in the worldwide electricity generation in 2020. [3] Presently, the global installed PV capacity is approaching 1 TW and it is envisioned to reach ≈10 TW by 2030 and 30 to 70 TW by 2050. [16] Interestingly, along with massive electricity production using conventional solar power plants and rooftop solar panels, ancillary concepts of PV offer new strategies for supplying modern systems in versatile applications. [17][18][19] Moreover, diverse functionalities beyond solar energy harvesting can be afforded by adaptive PV, including aesthetic appearance, visual comfort and thermal management. [17,18,20,21] The distributed nature and the ubiquitous accessibility of multifunctional PV products are substantial features of solar PV in contrast to other renewable energies. However, traditional SCs dominating the market impose intrinsic optoelectronic and thermomechanical limitations, that prohibit their multifunctional utilization. To overcome these drawbacks, novel functional materials and innovative device architecture Solar photovoltaics (PV) offer viable and sustainable solutions to satisfy the growing energy demand and to meet the pressing climate targets. The deployment of conventional PV technologies is one of the major contributors of the ongoing energy transition in electricity power sector. However, the diversity of PV paradigms can open different opportunities for supplying modern systems in a wide range of terrestrial, marine, and aerospace applications. Such ubiquitous and versatile applications necessitate the development of PV technologies with customized desig...

“…[9,10] Similarly, black silicon, a nanomaterial synthetized under laser irradiation that exhibits high aspect ratio nanoprotrusions, has early been proposed to assist photovoltaic cells for better conversion efficiency but also for bactericidal activity. [11,12] Ultrashort laser is then a promising candidate to control both surface hydrophobicity and bacterial activity on a cellular level due to nanopeaks distinct aspect ratio, controllable concentration, and periodicity. [13][14][15][16][17] For generating nanostructures, electron beam lithography, [18] metal assisted chemical etching, [19] or focused ion beam milling [20] are routinely employed.…”

The capacity to synthesize and design highly intricated nanoscale objects of different sizes, surfaces, and shapes dramatically conditions the development of multifunctional nanomaterials. Ultrafast laser technology holds great promise as a contactless process able to rationally and rapidly manufacture complex nanostructures bringing innovative surface functions. The most critical challenge in controlling the growth of laser‐induced structures below the light diffraction limit is the absence of external order associated to the inherent local interaction due to the self‐organizing nature of the phenomenon. Here high aspect‐ratio nanopatterns driven by near‐field surface coupling and architectured by timely‐controlled polarization pulse shaping are reported. Electromagnetic coupled with hydrodynamic simulations reveal why this unique optical manipulation allows peaks generation by inhomogeneous local absorption sustained by nanoscale convection. The obtained high aspect‐ratio surface nanotopography is expected to prevent bacterial proliferation, and have great potential for catalysis, vacuum to deep UV photonics and sensing.
