Formation of PCDTBT:PC₇₁BM p–n junction composite nanotubes via a templating method

Abstract

The use of a templating method to synthesize a p–n junction composite of PCDTBT:PC71BM is reported in this study.

Determining the Effect of Centrifugal Force on the Desired Growth and Properties of PCPDTBT as p-Type Nanowires

“…The diverse choice of infiltration forces has evidently produced an impact on shaping assorted morphologies and distribution of the produced nanostructures. The crumpling phenomena of the nanostructure tips, usually occurring during the etching process and clumping the nanotubes or nanorods into small islands, has been studied by Silverberg and co-workers as an interaction of Van der Waals between the two nanostructures [2, 3, 26–30]. At infiltration rates lower than 4000 rpm (800–3000 rpm), the nanorods are clearly distinguished from the nanotubes which can be evidenced from their tips in which the open-end tips are signed as nanotubes, meanwhile the closed-end tips are nanorods.…”

Modulation of Binary Neuroplasticity in a Heterojunction-Based Ambipolar Transistor

“…As depicted in Figure e, strong Raman-active vibrations at around 712, 1061, 1327, 1370, 1416, 1471, and 1513 cm –1 are originated from the PDPPBTT molecular motion, which are assigned to the C–S stretching in the symmetrical direction, in-plane C–H bending, C–H bending inside the moiety of the bithiophene (BTT) structure, CC stretching inside the moiety of diketopyrrolopyrrole (DPP), C–C stretching in the ring of the BTT structure, CC stretching in the structure of thiophene, and C–C stretching, respectively . Comparably, no vibration shift can be observed for the PDPPBTT/ZnO film with respect to the PDPPBTT film, indicating the physical contact between the ZnO film and the PDPPBTT film . The reduced intensity of the distinguishable active vibrations at 1416 cm –1 emphasizes the charge transfer into the electron-deficient BTT structure of the PDPPBTT film upon interacting with the ZnO film …”

Light Management Investigation of Transparent DSSC based on Ln3+ ion doped BaO-ZnF2-B2O3-TeO2 Glass (Ln3+ = Dy3+/Sm37Eu3+) as UV Down-conversion Material

“…Further investigation for glass composition and rare earth dopants in DC glass for increasing DSSC efficiency are needed such as Eu 3+ /Yb 3+ co-doped SrAl2O4 [8], SiNx: Tb 3+ /Yb 3+ [16], Pr 3+ /Yb 3+ co-doped gallo-germanate glass [17], etc. Indeed, the absorption band examination of other solar cell active layer types that have broad absorption wavelengths such as crystalline or polycrystalline silicon [6], PTB7:PC71BM [18], PCDTBT: PC71BM [19], or dyeA [20] is also required to find the most suitable active layer for Eu 3+ ion based-DC glass.…”
