Summary: Solution-processed semitransparent organic solar cells (ST-OSCs) are demonstrated using a polymer donor, PM6, and a small molecule acceptor, Y6, to achieve high power conversion efficiency (PCE) and average visible transmittance (AVT). The use of conductive polymer PEDOT:PSS as the top electrode contributes to the high efficiency. The approach of combining a low fraction of visible-wavelength-selective polymer donors with near-infrared nonfullerene acceptors proves to be effective in achieving high PCE and AVT simultaneously, making the ST-OSCs promising candidates for building-integrated photovoltaics.

Summary: Light-emitting diodes based on halide perovskites have achieved significant progress in recent years, with external quantum efficiencies surpassing 23%. However, their practical application is still limited due to factors such as low efficiency in blue-emitting devices, inability to access emission wavelengths above 800 nm, decreased external quantum efficiency at high current density, lack of understanding of the electric field's effect on mobile ions in perovskite materials, and short device lifetimes. This review explores the development of perovskite light-emitting diodes, examining the key challenges in creating efficient and stable devices.

Summary: In this study, carbon nanodots are shown to play a beneficial role as electron transport materials in OLEDs and OSCs. The properties of both pristine and nitrogen-functionalized carbon dots are systematically studied using various techniques to uncover their energetic alignment and interaction with the organic semiconductor's emissive layer. The results reveal significant improvements in the current and luminescent characteristics of the OLED devices, mainly due to a decrease in electron injection barrier. The power conversion efficiency of the OSCs using carbon dots as cathode interfacial layers also increases by nearly 10% compared to the reference device. The use of low-cost solution-processed materials in OLEDs and OSCs has the potential for widespread implementation in large-area applications.

Summary: Perovskite light-emitting diodes (LEDs) have shown great potential for display and lighting applications with external quantum efficiencies exceeding 20% for various colors. However, the majority of internally generated photons are trapped in the devices and lose energy through lossy channels, suggesting the need for effective light management strategies. By analyzing the intrinsic optical properties of perovskite materials and the extrinsic properties related to device structures, this Review highlights the possibility of substantially exceeding the conventional limits of planar organic LED devices and suggests new approaches for achieving ultrahigh efficiencies in perovskite LEDs.

Summary: Polyacrylic acid complexed with polyaniline (PAA/PANI) composite materials have the potential to form organic mixed ion-electron conductive (OMIEC) films, which can be used in optoelectronic and energy storage applications. The composite films are formed through an acid-base reaction, resulting in strong electrostatic interactions and intermolecular hydrogen bonds between PANI and PAA. The separation of PANI-rich domains from PAA-rich matrix in the composite films is observed. The electrical conductivity of the composite films is higher when the content of PANI is 33 wt%, due to the high ionic-electronic coupling at the interface between phase-separated regions.
