Self-Assembled Dense Colloidal Cu2Te Nanodisk Networks in P3HT Thin Films with Enhanced Photocurrent

摘要: The integration of colloidal nanocrystals with polymers adds optoelectronic functionalities to flexible and mechanically robust organic films. In particular, self-assembled structures in can act as functional components enhancing, for instance, transport or optical properties the hybrid material. This study presents Cu2Te hexagonal nanodisks that assemble into ribbons a face-to-face configuration poly(3-hexylthiophene-2,5-diyl) through controlled solvent evaporation process. form weaving patterns create 3D networks fully embedded thin polymer film at high nanodisk concentration. photoresponse these composite films measured layered vertical geometry demonstrates increased photocurrent increasing nanocrystal loading. attributes this behavior presence bulk heterojunction semiconducting polymer, which improves exciton dissociation overall photoelectric response.
