Dithienopyrrole-based oligothiophenes for solution-processed organic solar cells.
Isomeric dicyanovinylene-terminated oligothiophenes 1 and 2 comprising a central dithienopyrrole (DTP) unit have been developed for solution-processed small molecule organic solar cells (SMOSCs) giving the highest power conversion efficiency of 4.8% for DTP-based oligomeric materials.
متن کاملThermally Stable Solution Processed Vanadium Oxide as a Hole Extraction Layer in Organic Solar Cells
Low-temperature solution-processable vanadium oxide (V₂Ox) thin films have been employed as hole extraction layers (HELs) in polymer bulk heterojunction solar cells. V₂Ox films were fabricated in air by spin-coating vanadium(V) oxytriisopropoxide (s-V₂Ox) at room temperature without the need for further thermal annealing. The deposited vanadium(V) oxytriisopropoxide film undergoes hydrolysis in...
متن کاملSolution-processed organic photovoltaics based on indoline dye molecules developed in dye-sensitized solar cells.
A donor-acceptor (D-A) type indoline dye, D149, was used as an electron donor in solution-processed organic solar cells (OSCs). For bulk-heterojunction (BHJ) type OSCs with PC70BM as electron acceptor, the power conversion efficiency (PCE) is sensitive to the amount of D149 in the D149/PC70BM blend film. When the concentration of D149 in the blend film was as low as 5%, the highest PCE of up to...
متن کاملNew acceptorep-porphyrinep-acceptor systems for solution- processed small molecule organic solar cells
Two new conjugated acceptoredonoreacceptor (Aep-Dep-A) compounds having a Zn-porphyrin acting as donor and linked by ethynylenes to one or two units of thienylenevinylene and capped by dicyanovinylene groups as acceptor units have been synthesized and their photophysical and electrochemical properties were investigated. These compounds were used as donor materials and PC61BM and PC71BM were use...
متن کاملA star-shaped oligothiophene end-capped with alkyl cyanoacetate groups for solution-processed organic solar cells.
A star-shaped oligothiophene based on triphenylamine as a core and 2-ethylhexyl cyanoacetate as end groups (S(TPA-3T-CA)) was synthesized. S(TPA-3T-CA) exhibited strong absorption and high hole mobility. Solution-processed solar cells based on S(TPA-3T-CA):PC(71)BM showed a power conversion efficiency of 3.60% and a fill factor of 0.56.
