New di-anchoring A-π-D-π-A configured organic chromophores for DSSC application: sensitization and co-sensitization studies.
The design and synthesis of three new un-symmetrical metal-free carbazole based organic dyes, E1-3 with A- π-D-π-A architecture, as effective di-anchoring sensitizers in DSSCs are reported, finding that the device fabricated with the E1 sensitizer displayed the highest PCE of 2.38% among the three dyes.
Studies on third-order nonlinear optical properties and reverse saturable absorption in polythiophene/poly (methylmethacrylate) composites
We report here the studies on third-order nonlinear optical properties of two novel polythiophene composite films investigated using the Z-scan technique. The measurements were carried out using a
