“…The larger absorption and the faster mobility led to a significant increase in photoconductivity. 25 As shown in Figure 3, the larger photoconductivity of sample 1, compared to the other samples, confirms that in the presence of P3HT the photo-charge generation and mobility of carriers is significantly enhanced.…”

“…22 Poly(3-hexylthiophene) (P3HT) has emerged as a promising material and is currently the subject of intense research because it has good stability, a reasonably high hole mobility (in the range of 0.1 cm 2 V -1 s -1 ), and field effect mobility. [23][24][25] This field effect mobility can be as high as 0.01-0.045 cm 2 V -1 S -1 in high quality, self-organized samples. 26 P3HT has been used recently in the fabrication of electronic devices such as light emitting diodes, 27 solar cells, 28 and thin film field effect transistors 29 on flexible substrates.…”

This study examined the effects of poly(3-hexylthiophene) (P3HT) as a photosensitizer on the dynamic and steady-state photorefractive (PR) performance of polymeric composites. The performance was measured in terms of the magnitude and buildup speed of the PR grating. Absorption quenching was observed in a PR composite that was doped with P3HT/fullerene (C 60 ). This absorption quenching was attributed to disordering of the P3HT chains, and charge transfer between P3HT and C 60 . The magnitude and buildup speed of the PR grating were strongly dependent on space charge formation, which was affected by visible light absorption and the hole mobility.

Photorefractive polymer composites were synthesized based on poly (N-vinylcazbazole) (PVK) doped with liquid nonlinear optical chromophores and a sensitizer C 6 0 . PVK/liquid NLO chromophores/C 6 0 devices showed no signs of phase separation and did not require a plasticizer, such as ethylcarbazole. The composites showed 69% diffraction efficiency (C3) and a rapid response time of 46 ms (C1) in four-wave mixing experiments at a light intensity of 60 mW/cm 2 and a wavelength of 633 nm.

We report photorefractive (PR) polymer composites doped with 2-piperidino-5-thienylmalononitrile chromophore. The PR polymer composites showed a glass transition temperature of 25~27 o C, good transparency at 633 nm and long shelf lifetimes at room temperature. The PR polymer composites with a thickness of 100 µm showed a maximum diffraction efficiency of 77~91% and a rapid response time of 110~980 ms at the glass transition temperature. In addition, the composite C3 was observed at a video-rate response time at 35 o C.
