Summary: Perylene diimide (PDIN) derivatives with diverse ionic functionality were synthesized and applied as the cathode interlayer (CIL) in inverted-type non-fullerene organic solar cells (NFOSCs). The PDIN derivatives showed comparable power conversion efficiency to the ZnO layer and demonstrated their effectiveness as an oxygen-blocking layer at the device interface even after 30 hours of thermal and photo-aging. By adjusting the energy level alignment at the cathode interface, the side group enhanced electron extraction in the devices. This study provides insights into the fabrication of low-temperature processable ZnO-free NFOSCs.

Summary: Linking multiple perylene diimide (PDI) directly or with congested spacers is a reliable strategy for constructing high-performance non-fullerene acceptors (NFAs). Ethylene fused PDI dimer (PDI2) has also emerged as an alternative building block for NFAs. In this study, two PDI2 dimers were constructed using hydrazine and 1,6-hexanediamine as linkers, and their photovoltaic performance was evaluated. The results demonstrate that modification at the imide groups is a robust strategy for constructing high-performance PDI2-based NFAs.

Summary: The field of organic solar cells has made rapid progress with the development of nonfullerene acceptors. Interfacial engineering, particularly the use of perylene diimide (PDI) small molecules as cathode interfacial materials, has been shown to enhance power conversion efficiency. However, the molecular aggregation and stacking caused by the high planarity of PDINN molecule affects the film morphology and charge transport efficiency. To address this issue, PDINN-S was synthesized by modifying the bay position of PDINN, leading to improved performance and stability of OSCs.

Summary: In this study, a pair of acceptor-donor-acceptor (A-D-A) type PDI2 derivatives, namely IDTIC-PDI and IDT-diPDI2, containing asymmetric and symmetric end-cap units were designed and synthesized. Organic solar cells (OSCs) based on these two molecules were fabricated and measured, showing that the asymmetric IDTIC-PDI based device exhibited a much higher power conversion efficiency (PCE) of 8.23% compared to the symmetric IDT-diPDI2 (5.21%). These results indicate that symmetry breaking is an effective approach to optimize the photovoltaic performances of PDI2 based OSCs.

Summary: This study investigates the influence of the polarity of polymer matrices on persistent room-temperature phosphorescence (pRTP). It is discovered that intense phosphorescence emission can be achieved in highly polar matrices such as polyacrylic acid (PAA). The dipole-dipole interaction between the polar fluorophore and polar matrix is proposed to stabilize the excited state and facilitate the generation of efficient room-temperature phosphorescence emissions.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
