Ternary Blend Solar Cells Based on a Conjugated Polymer With Diketopyrrolopyrrole and Carbazole Units

Frontiers in Energy Research, 2018
Herein, we have synthesized a low-bandgap polymer (PCDPP4T) consisting of diketopyrrolopyrrole (DPP) and carbazole (Cz) units in the main chain. The absorption coefficient is as high as 1.3 × 105 cm−1 for PCDPP4T, which is slightly higher than 1.0 × 105 ...

Self‐Healing and Stretchable Synaptic Transistor

Advanced Functional Materials, EarlyView.
A self‐healing stretchable synaptic transistor (3S‐T) is realized using a p‐PVDF‐HFP‐DBP/PDMS‐MPU‐IU bilayer as gate insulator, where dipole‐dipole interaction enhances polarization to achieve a large memory window. Leveraging its neuronal biomimicry, the synaptic transistor demonstrates electrically compatibility with the biological brain. Furthermore,

Diketopyrrolopyrroles: Synthesis, Reactivity, and Optical Properties [PDF]

Advanced Optical Materials, 2015
First reported by Farnum as much as 40 years ago, diketopyrrolopyrroles (2,5‐dihydropyrrolo[4,3‐c]pyrrolo‐1,4‐diones) are currently one of the most widely used dyes, with applications that span high‐quality pigments, field‐effect transistors, bulk‐heterojunction solar cells, dye‐sensitized solar cells, and fluorescence imaging.
