在硅片和玻璃片上,P3HT-T超薄膜主要为edge-on片晶取向,而在ITO上为edge-on和face-on混合取向(图4),混合取向片晶结构有利于载流子传输,Hall效应结果表明ITO上的P3HT超薄膜迁移率与玻璃片上的相似,因此,即使结晶度和有序度较低,ITO上...
然而,退火处理并没有明显增加薄膜表层和薄膜/衬底界面处的P3HT分子edge—on结构的结晶性。二维GIXRD实验结果表明:退火处理可以明显增加薄膜中P3HT分子edge—on结构结晶性、有序性以及晶粒取向的广泛分布;退火处理也使薄膜沿面内方向出现了结晶性较好的face—on结构。以上结果揭示出退火处理有利于薄膜表面、内部以及薄膜/...
for example, poly (3-hexylthiophene) (P3HT), as HTMs is another significant attempt. Nevertheless, P3HT adopts the “edge-on” stacking arrangement, that is the alkyl side chains directly contact perovskite film, which was found presenting an electronically poor contact...
molecules (0.39 nm) along CTCBhave successfully induced epitaxial growth (as shown inFigure 7). The P3HT chains locked onto the TCB lattice, forming highly ordered molecules parallel to CTCB(fiber axis). Furthermore, the increased amount of ‘face-on’ crystallites in the TCB-treated P3HT...
We believe that the crystalline structure of the obtained P3HT/PTCA-SMs blends is a combination of edge-on and face-on orientations, which enable the potential use of this material as an active layer in organic electronics. Keywords: optical properties; organic semiconductors; spectroscopic ...
二维掠入射X射线衍射的结果表明,这是由于低浓度溶液制备的薄膜中分子链从face-on取向为主转变为edge-on取向为主。相应的薄膜晶体管器件性能证明了edge-on取向对应着更高的载流子迁移率。doi:DOI: 10.11889/j.0253-3219.2013.hjs.36.110101李海东长春工业大学化学工程学院王鹏月高分子物理与化学国家重点实验室中科院...
同步辐射掠入射X射线衍射P3HT/PCBM薄膜Edge-on结构Face-on结构以聚己基噻吩(poly(3-hexyl-thiophene),P3HT)为电子给体材料和富勒烯的衍生物([6,6]-phenyl C61-butyric acid methyl ester,PCBM)为电子受体材料的有机光伏器件,其活性层中P3HT的结构有序性是制约器件光电转换性能的重要因素.本文采用同步辐射掠入射X...
The P3HT crystals were composed of face-on ((100) and (002) prisms) and edge-on ((020) and (002) growth planes) oriented chains with distinct qualities of crystallinity. Within 1.5 months of aging in 36% humidity at 34 degrees C, P3HT:PC71BM photovoltaics and some of their modified ...
Crystallinity analysis suggests that more ordered P3HT is observed near the interface for face-on and amorphous case, while no such trend is observed for edge-on and end-on configurations due to weaker interactions at the interface as evident from the considerably less negative interfacial energy. ...
The P3HT crystals were composed of face-on ((1 0 0) and (0 0 2) prisms) and edge-on ((0 2 0) and (0 0 2) growth planes) oriented chains. The lowest d-spacing values were acquired for the QD decorated P3HT nanofibers (d(1 0 0) = 13.41鈥 13.46 and d(0 2 0) = 3.39鈥...
