Summary: In this study, core/shell ZnO/TiO2 nanocomposite samples were prepared using the sol-gel method at different time spans. The sample prepared in the 15-minute time span (ZnTi15) exhibited the highest photocatalytic activity and charge carrier density, making it the optimal sample. The formation of a heterojunction at the ZnO/TiO2 interface could be attributed to the increased photocurrent density observed for the ZnTi15 sample.

Summary: Lead selenide quantum dots (PbSe QDs) possess remarkable features due to their adjustable bandgap and low-temperature synthesis. In addition to the efficient QDs active layer, the electron transport layer (ETL) also plays a significant role in achieving high-efficiency colloidal quantum dots solar cells (CQDSCs). Undoped and 1-3% lithium-doped zinc oxide (LZO) sol-gel is introduced as an ETL and incorporated into CQDSCs to achieve high efficiency. The results show that 2 wt% Li-doping in ZnO ETL significantly improves the conduction band minimum and transmittance, while reducing oxygen defect densities and film roughness compared to other ETLs. Furthermore, PbSe CQDSCs with 2 wt% Li-doped ZnO ETL demonstrate the highest power conversion efficiency (PCE) of 10.80%, which is 7.5% higher than ZnO-based PbSe CQDSCs. Similarly, LZO-based PbSe CQDSCs with 2 wt% Li-doping exhibit long-term stability for approximately 40 days. Li-doping in ZnO offers a promising approach for low-cost, high-performance CQDSCs.

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: 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.
