Diketopyrrolopyrrole derivatives for efficient NiO-based dye-sensitized solar cells.
Two new diketopyrrolopyrrole (DPP) based sensitizers (DPP-Br, DPPCN2) and a novel dyad DPP-NDI (NDI = naphthalene diimide) were synthesized and investigated for use in NiO p-type dye-sensitized solar cells (p-DSCs). The simple push-pull DPP-CN2 gives a promising photoconversion efficiency (PCE) of 0.07% with the iodide/triiodide electrolyte while the PCE of the dyad reaches 0.18% with a cobalt ...
متن کاملDiketopyrrolopyrrole-based acceptor polymers for photovoltaic application.
Developing new acceptor materials as alternatives to fullerene acceptors remains a challenge in the field of organic photovoltaics. We report on the synthesis and optoelectronic properties of three acceptor polymers bearing diketopyrrolopyrrole units in the main chain (PA, PB and PC). Their performance as the acceptor material in bulk heterojunction solar cells using P3HT as the donor material ...
متن کاملRational Design of Diketopyrrolopyrrole-Based Small Molecules as Donating Materials for Organic Solar Cells
A series of diketopyrrolopyrrole-based small molecules have been designed to explore their optical, electronic, and charge transport properties as organic solar cell(OSCs) materials. The calculation results showed that the designed molecules can lower the band gap and extend the absorption spectrum towards longer wavelengths.The designed molecules own the large longest wavelength of absorption ...
متن کاملA non-fullerene electron acceptor based on fluorene and diketopyrrolopyrrole building blocks for solution-processable organic solar cells with an impressive open-circuit voltage.
A novel solution-processable non-fullerene electron acceptor 6,6'-(5,5'-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis(thiophene-5,2-diyl))bis(2,5-bis(2-ethylhexyl)-3-(thiophen-2-yl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione) (DPP1) based on fluorene and diketopyrrolopyrrole conjugated moieties was designed, synthesized and fully characterized. DPP1 exhibited excellent solubility and high thermal stability ...
متن کاملDiketopyrrolopyrrole (DPP) functionalized tetrathienothiophene (TTA) small molecules for organic thin film transistors and photovoltaic cells
Two novel p-conjugated small molecules based on the electron-deficient diketopyrrolopyrrole (DPP) and the electron-rich fused tetrathienoacene (TTA) frameworks are synthesized and characterized. As verified in the bandgap compression of these chromophores by electrochemistry and density functional theory (DFT) computation, these DPP-TAA derivatives exhibit substantial conjugation and ideal MO e...
