PTAA, poly (triaryl amine), semiconductor is an organic p-type semiconductor with hole mobilities of 10 −3 up to 10 −2 cm 2 V −1 s −1 which results in a … WebPoly(3-hexylthiophene) (P3HT) is a regioregular semiconducting polymer. It is used in organic electronics primarily because of its regular end-to-end arrangement of side chain, which allows efficient Π-Π stacking of the conjugated backbones. On account of the alkyl side group, P3HT is rendered hydrophobic in neutral state.
WebAbstract Poly (triaryl amine) (PTAA) is one of the promising hole transport materials (HTM) for perovskite solar cells. Highly efficient PTAA-devices have been demonstrated in both direct (n-i-p) and inverted (p-i-n) architectures. In the inverted structures, the device suffers from poor coverage of the perovskite film over the hydrophobic PTAA surface. WebFluoro-PTAA (specifically known as 1F-PTAA), or poly (bis (4-phenyl) (4-fluoro-2-methylphenyl)amine, is a mono-fluorinated poly (triaryl)amine which is used as a hole transporting layer (HTL) for perovskite and polymer solar cells. With the substitution of the methyl to fluorine on the 4-postion, the HOMO energy level is significantly lowered ...
