“…The devices showed an obvious PCE improvement after laminating the textured PDMS films, as previously reported. [ 71–73 ] We noticed that the highest efficiency improvement was achieved based on 6k‐PDMS, which exhibited both high diffused transmittance and haze effect, which is much less studied in transparent OPV so far. This PCE enhancement was attributed to the synergy of the anti‐reflection and extended effective optical path lengths by haze, [ 74 ] which enabled the higher photocurrent in a certain active layer thickness.…”

Flexible photovoltaic devices are promising candidates for triggering the Internet of Things (IoT). However, the power conversion efficiencies (PCEs) of flexible organic photovoltaic (OPV) devices with high conductivity poly(3,4‐ethylene dioxythiophene):polystyrene sulfonate (PEDOT:PSS) electrodes on plastic are lagging behind the rigid devices due to the low transmittance of polyethylene terephthalate (PET)/PEDOT:PSS. Moreover, the poor stretchability of the commonly used plastic substrates largely hinders the practical application of wearable devices. Herein, a novel stretchable indium tin oxide (ITO)‐free OPV device with a surface‐texturing polydimethylsiloxane (PDMS) substrate for outdoor strong‐ and indoor dim‐light energy harvesting is reported. The high diffuse transmittance and haze effect of the substrate enable stretchable ITO‐free devices, yielding a high PCE of 15.3% under 1 sun illumination. More excitingly, the stretchable device based on textured PDMS/PEDOT:PSS maintains a comparable PCE of 20.5% (20.8% for the rigid device) under indoor light illumination. Notably, the stretchable device is much more insensitive to the light direction, maintaining 38.5% of the initial PCE at an extremely small incident angle of 10° (16.3% for glass/ITO‐based counterpart). The texturing stretchable substrate provides a new direction for achieving high performance and enhanced light utilization for the stretchable light‐harvesting device, suitable for indoor and outdoor applications.

“…A literature review showed that conically shaped structures show various properties and, therefore, can be applied in other fields. Nanoconical 3D a-Si and polydimethylsiloxane structures show interesting optical anti-reflection properties and can be used in photonics [117,118]. Conical Co microstructures can be applied in low-temperature solid-state bonding [53].…”

The development in the field of nanomaterials has resulted in the synthesis of various structures. Depending on their final applications, the desired composition and therefore alternate properties can be achieved. In electrochemistry, the fabrication of bulk films characterized by high catalytic performance is well-studied in the literature. However, decreasing the scale of materials to the nanoscale significantly increases the active surface area, which is crucial in electrocatalysis. In this work, a special focus is placed on the electrodeposition of nanocones and their application as catalysts in hydrogen evolution reactions. The main paths for their synthesis concern deposition into the templates and from electrolytes containing an addition of crystal modifier that are directly deposited on the substrate. Additionally, the fabrication of cones using other methods and their applications are briefly reviewed.

“…Recently, researchers have found that a bio-inspired moth-eye nanostructure exhibits outstanding broadband low reflectivity and high transmission with wide-angle incident light compared to conventional antireflective multilayer coatings [8][9][10][11][12][13][14][15][16]. This kind of bio-inspired nanostructure is considered an effective way to enhance the photoconversion efficiency of solar cells [17][18][19][20] or the visibility of displays [21][22][23].…”

Broadband antireflection (AR) coatings are essential elements for improving the photocurrent generation of photovoltaic modules or the enhancement of visibility in optical devices. In this paper, we report a hybrid nanostructured antireflection coating combination that is a clean and efficient method for fabricating a nanostructured antireflection coating (ARC). A multilayer thin-film was introduced between the ARC and substrate to solve the significant problem of preparing nanostructured ARCs on different substrates. In this way, we rebuilt a gradient refractive index structure and optimize the antireflective property by simply adjusting the moth-eye structure and multilayers. Subwavelength-structured cone arrays were directly patterned using a self-assembled single-layer polystyrene (PS) nanosphere array as an etching mask. Nanostructure coatings exhibited excellent broadband and wide-angle antireflective properties. The bottom-up preparation process and hybrid structural combination have the potential to significantly enhance the broadband and wide-angle antireflective properties for a number of optical systems that require high transparency, which is promising for reducing the manufacturing cost of nanostructured AR coatings.
