This paper reports side-chain-engineered polymer donors and a small-molecule acceptor that are capable of simultaneous charge energy transfer as the active layer for organic photovoltaics.
PBDTBO, a conjugated polymer comprising benzo[1,2-b:4,5-b']dithiophene (BDT) and 5,6-bis(octyloxy)benzo[c][1,2,5]oxadiazole (BO) units, exhibits deep HOMO energy level of -5.27 eV excellent solubility. A device incorporating PBDTBO [6,6]-phenyl-C(61)-butyric acid methyl ester (1:1, w/w) exhibited power conversion efficiency 5.7%.
We used Stille coupling of electron-rich benzo[1,2-b:4,5-b′]dithiophene (BDT) presenting conjugated alkylthiophene (T), alkylphenyl (P), or alkylfuran (F) side chains with electron-deficient alkoxy-modified 2,1,3-benzooxadiazole (BO) moieties to obtain a series two-dimensional, conjugated, D−π–A polymers (PBDTTBO, PBDTPBO, and PBDTFBO). The the BDT units altered solubility, conformations, electronic properties synthesized polymers, allowing tuning their photovoltaic when blended fullerenes....
We have used Stille coupling polymerization to synthesize a series of new donor–acceptor (D–A) conjugated random copolymers—PBDTT-BO-DPP—that comprise electron-rich alkylthienyl-substituted benzodithiophene (BDTT) units in conjugation with electron-deficient 2,1,3-benzooxadiazole (BO) and diketopyrrolopyrrole (DPP) moieties that complementary light absorption behavior. These polymers exhibited excellent thermal stability degrading temperatures higher than 340 °C. Each these copolymers (i)...
In this study, we incorporated molybdenum disulfide (MoS2) nanosheets into sol-gel processing of zinc oxide (ZnO) to form ZnO:MoS2 composites for use as electron transport layers (ETLs) in inverted polymer solar cells featuring a binary bulk heterojunction active layer. We could effectively tune the energy band composite film from 4.45 4.22 eV by varying content MoS2 up 0.5 wt %, such that was suitable photovoltaic devices based on poly[bis(5-(2-ethylhexyl)thien-2-yl)benzodithiophene-...
We employed ternary blends capable of energy transfer—a synthesized small molecule (SM-4OMe) comprising benzodithiophene (BDT) units (a designed for transfer), and a polymer (PTB7-TH) with BDT desired packing orientation, fullerene—as active layers single junction photovoltaic devices.
The effects of charge accumulation on fill factor (FF) are studied by using light intensity-dependent current-voltage and capacitance-voltage measurements based poly-{bi(dodecyl)thiophene-thieno[3,4-c]pyrrole-4,6-dione}:1(3-methyloxycarbony1)propyl-1-phenyl [6,6] (PBTTPD:PCBM) solar cells. We find that the FF un-annealed device shows a non-monotonic dependence intensity: first an increase then decrease with increasing intensity. This suggests both bulk recombination determine before thermal...
Organic field-effect transistor (OFET) memory devices incorporating the copolymer polystyrene-block-poly(4-vinylpyridine) (PS56k-b-P4VP8k) layer, which features a thickness-dependent micellar nanostructure (P4VP-core, PS-shell), as charge trapping layer can exhibit tunable windows for p-channel applications. For instance, window increased substantially from 7.8 V device 60 nm thick PS56k-b-P4VP8k to 21 27 an increase of more than 2.5 times. Using simultaneous synchrotron grazing-incidence...
Using a PS-<italic>b</italic>-PEO block copolymer in the active layer allowed effective tuning of small molecule morphology and enhanced device efficiency.
The production of graphite oxide from usually requires strong oxidants, concentrated acids, and a reaction time the order 100 h. In this study, we adopted highly efficient cathodic plasma (CP) process in which vapor envelope calorific effect provides instant oxidation expansion for producing plasma-expanded oxides (PEGOs) recycled electrodes (GEs) or high purity (HG), within 10 min without need oxidants acids. X-ray diffraction, photoelectron spectroscopy Raman confirmed dramatic structural...
Selected area electrochemical etching (EE) and deposition (ED) are widely used for fabricating microstructures devices, but they require complex processes expensive equipment generate significant electrolyte waste. This study demonstrates a novel single-droplet system using triboelectric nanogenerator (TENG) self-powered selected EE ED reactions. Utilizing TENG's pulsed power, Al nanostructures were created by EE, while nano-Ag Cu2O nanocubes synthesized ED. The generated nanomaterials...
