“…As seen in UV-vis spectrum, the VOPcPhO has portrayed the significant peaks absorption between 300 and 750 nm. The peak absorption of VOPcPhO thin film is located at 348 nm which assigned as Soret band (B band) and at 677 and 713 nm of Q band [2][3][4]8,9,18]. UV-vis spectrum of VOPcPhO thin film portrayed an extensive valley between 400 and 600 nm which in the UV-vis spectrum of PC 71 BM thin film shows its main peak absorption positioned within this valley.…”

“…This could be due to the existence of the significant variation in the ordering structure of composite nanotubes. The formation of composite nanotubes is expected to alter the molecular structure of VOPcPhO and 71 BM is too small to be considered influential [9].…”

“…Metal phthalocyanine nanostructures such as nanotubes, nanoflowers, nanorods, nanowires, and nanoribbons [3][4][5][6] have shown the remarkable approaches and the emergence of versatile fabrication. A spin coating technique has been implemented in fabricating the electronic devices (such as sensors and solar cells) with the incorporation of metal phthalocyanine as bulk heterojunction structure [1,[7][8][9]. Bulk heterojunction could be realized by blending the p-and n-type materials which then resulted to the interpenetrating structure.…”

“…It is considered as a macro-cyclic compound where its structure consists of four isoindole units surrounding the center metal atom. VOPcPhO also exhibits wide absorption in UV-vis spectral region between 300 and 750 nm [1][2][3][4][7][8][9]. In addition, metal phthalocyanine is capable to act as a sensitizer of photo-induced electron transfer to acceptors, which can be efficiently achieved by incorporating it with the fullerene groups such as [6,6]-phenyl C61 butyric acid methyl ester (PC 61 BM) and [6,6]-phenyl C71 butyric acid methyl ester (PC 71 BM) [15].…”

The use of templating method to synthesize the vanadyl 2,9,16,23-tetraphenoxy-29H,31H-phthalocyanine (VOPcPhO): [6,6]-phenyl C71 butyric acid methyl ester (PC 71 BM) composite nanotubes is presented here. VOPcPhO is a p-type material and PC 71 BM is an n-type material which acts as an electron donor and electron acceptor, respectively. Both materials have been studied due to their potential applications as solar energy converter and organic electronics. High-resolution transmission electron microscope (HRTEM) and field emission scanning electron microscope (FESEM) images have shown the replication of the porous template diameter of approximately 200 nm with a superior incorporation of both VOPcPhO and PC 71 BM. VOPcPhO:PC 71 BM composite nanotubes showed the significant properties improvement if compared over their bulk heterojunction counterpart. UV-vis spectra of composite nanotubes show a shift to a longer wavelength at the absorption peaks. Significant quenching has been attained by the photoluminescence spectra of VOPcPhO:PC 71 BM composite nanotubes which supports the redshift of UV-vis absorption spectra. Presumably, the photo-induced charge transfer and charge carrier dissociation can be enhanced from the VOPcPhO:PC 71 BM composite nanotubes rather than the bulk heterojunction.

Sandwich-like Ag-C-Ag nanoparticles (Ag-C-Ag NPs) were mildly synthesized under hydrothermal conditions in one step method. With this approach, Ag was not only encapsulated in the centre of an individual carbon nanosphere and was also uniformly dispersed within the carbon matrix up to the sphere's shell. Then, poly(3-hexylthiophene): Ag-C-Ag NPs (P3HT:Ag-C-Ag NPs) composite films were prepared by a spin coating method with a mixture chlorobenzene solution of Ag-C-Ag NPs and P3HT. Both morphology and microstructure of Ag-C-Ag NPs were investigated by field emission scanning electron microscopy and high resolution transmission electron microscopy. The possible formation mechanism was proposed.The results have indicated that the Ag-C-Ag NPs exhibit the good thermal stability and their energy level matches with that of P3HT. It has been observed that an introduction of Ag-C-Ag NPs to P3HT can induce broad and high absorbing spectra as well as a great photoluminescence quenching of P3HT. It is evident that sandwich-like Ag-C-Ag NPs have a great potential to be a new acceptor material in photovoltaic devices.
