SpletUltra-thin (<10 nm thick) blend films had greater P3HT order than the bulk and reorganised at lower temperatures, which we propose is due to a P3HT-rich interfacial layer at the film/air interface, and that extra disordered component retained despite annealing is due to P3HT trapped in a disordered state within the corresponding PCBM-rich ... SpletPCBM was spin-coated onto the ITO/ZnO substrates at 600 rpm for 60 s, resulting 28 nm thick film. The substrates were thermally annealed at 150 °C for 5 min inside a N2-filled glove box to introducing crystallization of PCBM. 10 mg/mL P3HT solution in chlorobenzene was spin-coated at 1000 rpm for 60 s, and resulting 47 nm P3HT film

Spletfilm morphological behavior. 2. Materials and Methods To study the effect of varying the thickness and composition ratio of Poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C60-butyric acid methyl ester (PCBM) thin film on optical absorption: A precursors for active layer organic solar cell fabrication. Thin film of P3HT:PCBM was SpletIn this study, we have analyzed the morphology of blends of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) formed upon solvent evaporation. We used the following deposition methods: dip-coating, droplet evaporation within a constrained geometry and drop-casting. clever ones crossword

SpletCompared with PCBM, PNP features a higher electronic mobility and stronger hydrophobic nature. The enhancement of power conversion efficiency was obtained from 5.12% to 8.23%, with an increase in short-circuit current density (Jsc) from 11.90 to 21.44 mA cm−2 and fill factor (FF) from 0.49 to 0.56 owing to insertion of optimum 10-nm-thickness ... Splet01. apr. 2024 · The AFM images of the P3HT:PCBM films annealed at different temperatures are presented in the supplementary material [Figs. S2(a)–S2(f)]. The surface roughness values of the films are summarized in Table S2 in the supplementary material.
