Summary: Non-fullerene organic photovoltaics (OPVs) have achieved high power conversion efficiencies (PCEs). By optimizing the blend morphology of a two-donor (PM6, TPD-3F)/one-acceptor (Y6) ternary blend, improved OPV performance was achieved. Good miscibility between PM6 and TPD-3F, combined with device optimization using 1-chloronaphthalene as an additive, resulted in efficient exciton dissociation and carrier transport for higher PCE.

Summary: The current state-of-the-art organic solar cells (OSCs) commonly use halogenated materials and solvents, which can be corrosive and harmful to the environment. Therefore, it is meaningful to explore and develop efficient and stable OSCs based on halogen-free materials and solvents. Researchers have successfully demonstrated that fully halogen-free OSCs can achieve efficient performance with an efficiency of 10.42% and superior thermal stability, due to the use of nonhalogenated active blend and processing solvent, which inhibit corrosion and preserve the initial efficiency for a prolonged period of time under high temperature conditions.

Summary: The thermal transport efficiency of organic semiconductors is lower compared to crystalline inorganic semiconductors. This study demonstrates that blending with an insulator, such as polystyrene, can enhance the heat conduction of organic semiconductors. The improved heat transfer is attributed to better intimate mixing and bridging between the host material and the insulator.

Summary: In this paper, the enhanced performance of organic solar cells (OSCs) with low band gap photoactive layers and 2D arrays of plasmonic nanostructures embedded at the back of the OSCs is demonstrated. The performance of the OSCs containing different plasmonic nanostructures is compared through finite-difference time-domain (FDTD) simulations. The results show that OSCs with 2D arrays of Ag nano-parabola at the back of the solar cell exhibit significantly improved short circuit current density and power conversion efficiency compared to planar OSCs, due to enhanced light scattering near the localized plasmon resonance of the metallic nanostructures.

Summary: In this study, inkjet printing technology is used to deposit sensitive materials as a vertically assembled nest-like array composed of petal-shaped nanoparticles. It overcomes the drawbacks of traditional MEMS-based deposition technology for gas sensor sensitive materials in terms of cumbersome and unstable operation. The mesoporous ZnO sensor exhibits high gas-sensing response to low concentration acetone due to the uniform small nanoparticles, multi-dimensional assembly structures, and abundant oxygen vacancy defects.

Summary: In this study, a translucent-colored passive daytime radiative cooling (TC-PDRC) strategy was proposed by embedding plain Au or Au@SiO2 core-shell nanoparticles in a polymeric polyvinyl alcohol matrix. The TC-PDRC films showed higher visible transmittance, lower visible absorptance, and higher infrared thermal emittance compared to conventional TC films, resulting in a reduced thermal load. Field measurements demonstrated that the temperatures of the chamber covered by TC-PDRC films were significantly lower than those covered by conventional TC film during the midday period.
