Transparent conductors are essential in many optoelectronic devices, such as displays, smart windows, light-emitting diodes and solar cells. Here we demonstrate a transparent conductor with optical loss of ∼1.6%, that is, even lower than that of single-layer graphene (2.3%), and transmission higher than 98% over the visible wavelength range. This was possible by an optimized antireflection design consisting in applying Al-doped ZnO and TiO layers with precise thicknesses to a highly conductive Ag ultrathin film. The proposed multilayer structure also possesses a low electrical resistance (5.75 Ω sq), a figure of merit four times larger than that of indium tin oxide, the most widely used transparent conductor today, and, contrary to it, is mechanically flexible and room temperature deposited. To assess the application potentials, transparent shielding of radiofrequency and microwave interference signals with ∼30 dB attenuation up to 18 GHz was achieved.

Power generation and architectural beauty are equally important for designing efficient and esthetically appealing bifacial perovskite solar cells (PSCs). In this work, efficient and multicolored p-i-n-structured PSCs are achieved by taking advantage of a dielectric/metal/dielectric (DMD)-type (MoO/Ni/Ag/MoO) transparent counter electrode. The MoO/Ni underlayer effectively promotes the formation of a continuous and conductive ultrathin Ag transparent film, especially the 1 nm Ni seed layer adjusts the interface energy level between perovskite/MoO and Ag, resulting in Ohmic contact of the electrode to promote charge extraction and collection.

Article Synopsis
- Long-wavelength infrared (LWIR) cameras struggle with sensitivity and exposure times due to reflections caused by high-refractive index lenses in compact optical systems.
- The scarcity of suitable transparent materials for LWIR complicates the design of effective antireflective coatings, limiting optimization options for creating efficient systems.
- This study utilizes a discrete-to-continuous optimization approach to design a subwavelength-thick antireflective multilayer coating for LWIR cameras, successfully achieving an average reflectance of 0.54% over the wavelength range of 8-13 μm with a coating made from five layers.

The issue of increased electromagnetic pollution has sparked widespread demands for electromagnetic interference (EMI) shielding technology in specialized applications such as optical windows and periscopes. More importantly, the materials maintaining a high transmittance and excellent EMI shielding stability in harsh environments still remain an urgent challenge. In this work, a multilayered PDMS/ITO/Ag/ITO (PIAI) film is constructed by magnetron sputtering and spin-coating techniques.

The development of new encapsulating coatings for flexible solar cells (SCs) can help address the complex problem of the short lifespan of these devices, as well as optimize the technological process of their production. In this study, new laminate-type protective composite coatings were prepared using a silicon oxynitride thin-film matrix obtained by curing the pre-ceramic polymer perhydropolysilazane (PHPS) through two low-temperature methods: (i) thermal annealing at 180 °C and (ii) exposure to UV radiation at wavelengths of 185 and 254 nm. Single-walled carbon nanotubes (SWCNTs) were used as fillers via dry transfer, facilitating their horizontal orientation within the matrix.
