Summary: In this study, dipole-assisted carrier transport properties of TFSI-treated O-ReS2 field-effect transistors were demonstrated. Results showed that the interaction between TFSI and O-ReS2 was more sensitive to external electric fields compared to pristine ReS2, leading to significantly increased drain current in O-ReS2 FET after treatment. The dipole direction in the treated O-ReS2 device was highly influenced by the voltage sweep direction, resulting in a significant area of hysteresis in I-V and transfer characteristics.

The addition of PACl increases perovskite grain size and significantly prolongs carrier lifetime. Compared to MACl, the PACl additive leads to better stability against moisture due to the in situ formed barrier at the bulk perovskite.

Summary: Electro- and photoinduced charge transfer in nanocrystalline mesoporous TiO2 film and TiO2/iron porphyrin hybrid films under CO2 reduction conditions were studied. The TiO2 film exhibited a reduction in the absorption and lifetime of photogenerated electrons under laser excitation and applied voltage. The TiO2/iron porphyrin films showed faster charge recombination kinetics and exclusive formation of CO during CO2 reduction. The competitive processes between oxidized iron porphyrin and TiO2 conduction band electrons were identified as the reason for the moderate performances of the hybrid films.

Summary: The development of commercially viable organic solar cells (OSCs) requires reducing the efficiency-stability-cost gap. This can be achieved by minimizing synthetic steps while maintaining molecular planarity and efficiencies achieved by fused ring acceptors (FRAs). Developing non-fused ring acceptors (NFRAs) with suitable functionalization for conformational planarity and molecular packing can be cost-effective. Although NFRAs currently have a power conversion efficiency (PCE) of around 16%, lower than FRAs' 19%, understanding their effective structural design is crucial for efficient OSC development. This article focuses on the molecular design concept for NFRAs in recent years and analyzes the approach to material design and efficiency improvement, a significant step toward technological application.

Summary: This work focuses on the application of hydrated vanadium pentoxide (HVO) as a hole transport layer (HTL) in organic solar cells (OSCs). The simple synthesis process of HVO as the anode HTL in non-fullerene-acceptor-based binary and ternary OSCs enables a higher power conversion efficiency (PCE). The comparison experiments show that the OSCs based on ITO/HVO anode exhibit a higher PCE than those based on ITO/PEDOT:PSS anode.
