Conjugated Polymers for Organic Solar Cells
Energy shortage has become a worldwide issue in the 21st century (Lior, 2008). The urge to look for renewable energy to replace fossil fuel has driven substantial research effort into the energy sector (Hottel, 1989). The solar energy has enormous potential to take the place due to its vast energy stock and availability worldwide (Balzani et al., 2008). Conventional solar energy conversion devi...
متن کاملWide band gap diketopyrrolopyrrole-based conjugated polymers incorporating biphenyl units applied in polymer solar cells.
Incorporating biphenyls as co-monomers in electron-deficient diketopyrrolopyrrole (DPP) conjugated polymers enables widening the optical band gap to 1.70 eV. Power conversion efficiencies of 3.7-5.7% and high open-circuit voltages of 0.80-0.93 V are obtained in solar cells based on these wide band gap DPP polymers.
متن کاملAqueous Processing for Printed Organic Electronics: Conjugated Polymers with Multistage Cleavable Side Chains
The ability to process conjugated polymers via aqueous solution is highly advantageous for reducing the costs and environmental hazards of large scale roll-to-roll processing of organic electronics. However, maintaining competitive electronic properties while achieving aqueous solubility is difficult for several reasons: (1) Materials with polar functional groups that provide aqueous solubility...
متن کاملSynthesis of annulated thiophene perylene bisimide analogues: their applications to bulk heterojunction organic solar cells.
Annulated thiophene perylene bisimides and their triphenyl-amine based oligomers have been synthesized. One of the oligomers FPTTPA has been demonstrated to be an efficient electron donor in bulk heterojunction (BHJ) organic solar cells, giving a power conversion efficiency of 1.42%.
متن کاملConjugated polymer-based organic solar cells.
Photovoltaics (PVs) consists of the harvesting of energy from sunlight and its conversion into electrical power. This technology is being increasingly recognized as one of the key components in our future global energy scenario. Limited fossil fuel resources and steadily increasing costs of supplying fossil fuels to the market induce a natural limit where renewable energies will begin to kick i...
