Small-molecule photovoltaics based on functionalized squaraine donor blends.
نویسندگان
چکیده
Two squaraine (SQ) donor molecules with different absorption bands are blended together for better coverage of the solar spectrum. The blend SQ device shows a significant improvement compared with single SQ donor devices. By applying a solvent annealing process and a compound buffer layer, a power-conversion efficiency of 5.9 ± 0.3% is achieved under 1 sun illumination.

Small molecule-based tandem solar cells with solution-processed and vacuum-processed photoactive layers.
A tandem solar cell device whose sub-cells are fabricated exclusively from small molecules (SMs) through both solution-processed and vacuum-processed deposition techniques is described. The front sub-cell's active layer consists of a bulk heterojunction (BHJ) DPP(TBFu)2:PC70BM device while the back cell has a typical bilayer structure employing a 2,4-bis[4-(N,N-diisobutylamino)-2,6-dihydroxyphe...
متن کاملSpiro-fluorene based 3D donor towards efficient organic photovoltaics.
A novel 3D donor material (SF8TBT) based on spiro-fluorene has been developed. Compared with the corresponding 1D linear molecule, the OPVs of this 3D donor exhibited power conversion efficiencies of 4.82%, much higher than that of 1D small molecules (1.69%).
متن کاملAggregation-dependent photovoltaic properties of squaraine/PC61BM bulk heterojunctions.
In this study, we investigated bulk-heterojunction solar cells composed of PC(61)BM and squaraine dyes with different donor subunits. Both, H- and J-aggregates, have been observed for the squaraine dyes in the mixture, even for the same dye depending on the annealing conditions of the blends. Supramolecular organization of the squaraine dyes noticeably affects solar cell performance. The J-aggr...
متن کاملEfficient synthesis of fluorescent squaraine rotaxane dendrimers.
A squaraine rotaxane scaffold with four alkyne groups is readily converted into a range of dendritic architectures using high-yielding copper-catalyzed alkyne azide cycloaddition (CuAAC) chemistry. A convergent synthesis approach is more efficient than a divergent pathway. Dendritic squaraine rotaxanes with peripheral amine groups can be further functionalized to produce multivalent deep-red fl...
متن کاملA sensitive colorimetric and fluorescent sensor based on imidazolium-functionalized squaraines for the detection of GTP and alkaline phosphatase in aqueous solution.
Imidazolium-functionalized squaraine ImSQ8 is synthesized as a sensitive colorimetric and fluorescent chemosensor for GTP in aqueous solution. The detection limit of GTP reaches 5.4 ppb. Its applications in the live-cell imaging and enzyme activity assay have also been demonstrated.
