The photovoltaic performance of polymer bulk heterojunction solar cells is studied systematically. Using a new benzodithiophene (PTB7) and PC71BM (see figure) power conversion efficiency 7.4% has been achieved in PTB7/PC71BM-blend film, indicating great potential bright future for (FF = fill factor, PCE ;= power-conversion efficiency). Detailed facts importance to specialist readers are published as ”Supporting Information”. Such documents peer-reviewed, but not copy-edited or typeset. They...
Poly(3,4-ethylenedioxythiophene) (PEDOT) is an excellent hole-conducting polymer able to replace the liquid I-/I3- redox electrolyte in dye-sensitized solar cells (DSCs). In this work we applied situ photoelectropolymerization technique synthesize PEDOT and carried out a careful analysis of effect different doping anions on overall cell performance. The analyzed are ClO4-, CF3SO3-, BF4-, TFSI−. best performance was observed when TFSI- anion used. Photoelectrochemical impedance studies reveal...
Conductive polymers have been widely applied as counter electrodes in dye-sensitized solar cells. However, one of many materials the conductive polymer family, polypyrrole attracts little attention this field. In paper, (PPy) was synthesized by vapour phase polymerization (VPP) and electropolymerization (EP) these PPys were employed Comparing to regularly used Pt electrode, both them show good catalytic behaviour cells though PPy a slightly lower fill factor. Such investigation will broaden...
Poly(3,4-ethylenedioxythiophene) (PEDOT) is an excellent kind of conducting polymer, comparable to Pt in catalytic behavior dye-sensitized solar cells. Electrochemical polymerization the presence different anions (doping ions) that work as counterions resulting oxidized state PEDOT has been carried out verify influence doping ions on photo-electron conversion performance and photo-electrochemical measurements reveal interaction between polymer substrate (FTO) directly influences fill factor...

In dye-sensitized TiO2 solar cells, charge recombination processes at interfaces between fluorine-doped tin oxide (FTO), TiO2, dye, and electrolyte play an important role in limiting the photon-to-electron conversion efficiency. From this point of view, a high work function material such as titanium deposited by sputtering on FTO has been investigated effective blocking layer for preventing electron leakage from without influencing injection. X-ray photoelectron spectroscopy analysis...
Novel polyporphyrins with high surface area over 1500 m2/g have been synthesized, and their hydrogen absorption capacities were measured. Porphyrin functionalized thiophenyl groups was designed as starting monomer; the porphyrin cores offer coordination sites for metal ions which could potentially enhance interaction favorable storage while are used cross-linking monomers under oxidative coupling conditions to yield highly porous networks. These adsorb up 5.0 mass % H2 at 77 K 65 bar....
High work function material V2O5 with Al as a composite electrode is applied first counter in solid dye-sensitized solar cell (solid DSC). Such novel gives over 2% conversion efficiency, which comparable noble Ag electrode. In addition, such and concept would be widely used other noniodine-based DSCs. The replacement of regular Au, metal electrodes way to reduce the cost DSC large scale production.
