Summary: Antimony selenosulphide (Sb-2(S,Se)(3)) has rapidly developed recently due to its optoelectronic properties, low cost, and other advantages. However, the instability and high cost of the Spiro-OMeTAD material used in Sb-2(S,Se)(3) solar cells have limited their large-scale application. To address these issues, researchers have introduced various phthalocyanine hole transport layers (HTLs) to improve the stability and efficiency of Sb-2(S,Se)(3) solar cells.

Summary: Antimony selenosulphide (Sb-2(S,Se)(3)) has great potential in thin film solar cells due to its adjustable band gap, high light absorption coefficient, and excellent optoelectronic properties. However, the stability and cost of Spiro-OMeTAD, a commonly used hole transport material, limit its large-scale application in Sb-2(S,Se)(3) solar cells. In this study, we demonstrate stable and efficient Sb-2(S,Se)(3) solar cells using phthalocyanine as a hole transport layer, which shows improved valence band alignment and carrier transport capability compared to Spiro-OMeTAD.

Summary: Silver thin films decorated with carbon nanoparticles were prepared by ablating Ag/C thin film with an Nd: YAG fiber pulsed laser, resulting in a shift of Surface plasmon resonance (SPR) wavelength. Surface enhanced Raman scattering (SERS) was observed in Ag/C samples due to decorating with nano-carbon, showing good stability and high SERS intensity with Rhodamine 6G (Rh 6G) concentration of 10^(-5) mol/L. Simulation results of finite-difference-time-domain (FDTD) confirmed the SERS performance.

Summary: This study demonstrates that the use of a static, strong magnetic field can improve the microstructure of phthalocyanine (Pc) thin-films, leading to a twofold increase in the mobility of organic thin-film transistors (OTFTs). The magnetic field increases the concentration of oxygen-induced radical species within the Pc thin-film, resulting in magnetic field induced changes to its microstructure and improved charge transport characteristics.

Summary: Tin(IV) phthalocyanines show promise as low-cost materials for organic electronic devices, but are relatively understudied compared to their silicon analogues. This study synthesized seven novel SnPcs and investigated their performance in OPVs and OTFTs. While these materials decreased efficiency as ternary additives in OPVs, four of them exhibited higher electron field-effect mobilities in OTFTs compared to SiPc analogues.

Summary: Plasmonic nanoparticles (NPs) were used to enhance photon harvest in organic solar cells (OSCs). By incorporating hybrid silver/silver-oxide (Ag/Ag2O) NPs in the hole transport layer (HTL) PEDOT:PSS, OSCs based on poly(3-hexylthiophene) (P3HT) and (6,6)-phenyl-C61-butyric acid methyl ester (PCBM) showed improved conductivity, optical absorption, aggregation, and power conversion efficiency. The significant improvement in the power conversion efficiency was attributed to the synergistic enhancement in exciton generation, dissociation, charge collection, and dissociation probability.

Summary: This work demonstrates how the current phase transition of atomic Bose-Einstein condensates in a trap can be controlled by applying an oscillatory driving field. The self-trapping effect in momentum space allows for a suppression of oscillations and a nearly constant directed current. Mean-field chaos serves as an indicator of the quantum phase transition. These findings are supported by an effective three-mode model.

Summary: The melting line of cobalt was investigated through experimental and theoretical methods, revealing a phase transition from hexagonal close-packed structure to face-centered cubic structure at high temperatures. The melting temperatures obtained from both methods showed good agreement and can be described by a Simon-Glatzel equation. Additionally, a thermal equation of state for the face-centered cubic phase of cobalt was determined.
