AI总结:

本文比较BHBT2:PC71BM本体异质结与模板法复合纳米管的形貌、结构及光学性质,证明PC71BM可渗入纳米管,但因分布不均导致其载流子输运不如本体异质结。

摘要:

在本研究中,我们研究了由噻吩基小分子BHBT2和富勒烯PC71BM组成的本体异质结与复合纳米管的形貌、结构和光学性质。分别采用混合共混法和模板辅助法制备本体异质结和复合纳米管。研究还包括分别通过旋涂法和模板辅助法制备的单一材料BHBT2薄膜和纳米管。比较了本体异质结与复合纳米管之间两种不同的形成方式,以阐明它们在性能方面的提升。BHBT2:PC71BM本体异质结和复合纳米管的吸收光谱均处于紫外-可见(UV-vis)范围内。场发射扫描电子显微镜(FESEM)和高分辨透射电子显微镜(HRTEM)图像表明,富含碳的PC71BM已成功渗入BHBT2纳米管中,形成BHBT2:PC71BM复合纳米管。然而,由于渗入分布不规则,电荷载流子输运在本体异质结中优于复合纳米管。

英文摘要:

In this study, we investigate the morphological, structural, and optical properties of both bulk-heterojunction and composite nanotubes that composed of thiophene-based small molecules BHBT2 and fullerene PC71BM. Mix-blended and template-assisted methods were used to fabricate the bulk-heterojunction and composite nanotubes, respectively. A single material of BHBT2 thin films and nanotubes that fabricated via spin-coating and template-assisted methods, respectively, was also studied. Two different formations between bulk-heterojunction and composite nanotubes were compared to elaborate their advancement in properties. Absorption spectra of BHBT2:PC71BM bulk-heterojunction and composite nanotubes have fallen within the ultraviolet-visible (UV-vis) range. Field emission scanning electron microscope (FESEM) and high-resolution transmission electron microscope (HRTEM) images show that the carbon-rich of PC71BM, has successfully infiltrated into the BHBT2 nanotube to form the BHBT2:PC71BM composite nanotubes. However, due to the informality distribution of infiltration, charge carrier transfer is seen to be better in bulk-heterojunction rather than in the composite nanotubes.
