We found that the increase in the absorbed energy by the optimal moth eye structure was particularly large at longer wavelength of ~620 nm, which is slightly below the wavelength corresponding to the band gap of P3HT (653 nm).
We fabricated CN-DOQA from the blend with effective polymer donor P3HT in dichlorobenzene by spin coating and blend solutions were prepared in 1, 2-dicholobenzene with different ratios.
P3HT and PCBM were chosen for use in a bulk heterojunction cell, as they are the most widely accepted materials.
23], which describes the synthesis and characterization of copolymers based on P3HT and poly (3-hexyloxythiophene) (P3HOT) monomer units, indicates that this ability to make a prediction is not restricted to copolymers derived from the same base polymer, and can be extended to at least copolymers that have similar comonomers.
A blend of poly (3-hexylthiophene) (P3HT) (Rieke Metals, Mw 48000, regioregularity 93%) and PCBM (Ossila) was prepared by mixing a solution of P3HT (12mg/ml) and PCBM (10mg/ml) dissolved in chlorobenzene and spin coated at 1250 RPM for 40s.
Alkane dithiols have been the best recognized category of "processing additive," effectual in modifying the morphology in quite a lot of polymer classifications including classical P3HT donor polymer as well as for group of some low band gap polymers.
The cosolvent, which is added in small amounts to the blend, controls the aggregation of P3HT in the blend mixture owing to the lesser solubility of P3HT chains in this added co-solvent [12].
Electrical bistability was also demonstrated in a polymer memory device with an active layer consisting of P3HT and gold nanoparticles (AuNPs) capped with 1-dodecanethiol sandwiched between aluminum bottom and top electrodes [41].
It is desired that the wetting gradient between the adhesion work of one microphase PS and P3HT [W.
With increased packing and order of molecules, charge mobility substantially increases in high molecular weight and less branched PF and poly(3-hexylthiophene) P3HT (6), (7).
The PL quenching of the P3HT was ascribed to rapid charge transfer from the photo excited states [36].
This configuration-related disorder may be used to explain the changes in carrier mobility in P3HT field-effect transistors at elevated temperature [9].
