Photoactive Copper Complexes: Properties and Applications

“…Some progress based on the use of photoactive copper complexes in dye-sensitized solar cells has also been reported, including the development of polymeric ligands with donor and acceptor units which, complexed to copper, showed an excellent performance, with a PCE of 6.82% . Such polymeric dyes based on other ligands were moreover further studied. , A review article including recent advances in copper dyes for dye-sensitized solar cells has also been published . Finally, eight new heteroleptic [Cu­( NN ) Ancil ( NN ) Anchor ] + complexes have also been investigated in an in silico study, with the charge transfer directionality being studied as a function of the ancillary ligand …”

Quantum chemical modification of indaceno dithiophene-based small acceptor molecules with enhanced photovoltaic aspects for highly efficient organic solar cells

“… 49 The shorter E gap of all the molecules resulted in a longer wavelength due to the inverse connection of energy and wavelength. 50 The IDSTR and IDST1–IDST7 molecules' rising λ max trend in the gas phase and in the CHCl 3 is IDSTR < IDST5 < IDST7 < IDST4 = IDST1 < IDST6 < IDST2 < IDST3 and IDSTR < IDST5 < IDST7 < IDST4 < IDST6 < IDST1 < IDST2 < IDST3, respectively. The outcomes reveal that IDST3 has the highest λ max in gas and solvent phases, at 701 nm and 770 nm, respectively, which may be due to the pairs of electronegative cyano group presence in the peripheral acceptor unit.…”

Engineering of W-shaped benzodithiophenedione-based small molecular acceptors with improved optoelectronic properties for high efficiency organic solar cells

“…Because of the inverse relationship between energy and wavelength, the reduced E gap of all the molecules caused their wavelength to increase. 66 When compared to the absorption maxima of the Y6 molecule, both the W1 and W2 molecules have shown a red-shift in their respective λ max values. W1 and W2 molecules exhibit a 17 nm and a 5 nm bathochromic shift, respectively, when compared to Y6.…”
