title: New D-A-π-A organic sensitizers for efficient dye-sensitized solar cells.
abstract: Four novel metal-free D-A-π-A organic sensitizers (ND01-ND04) based on N-annulated perylene (NP) derivatives as efficient electron donors for dye-sensitized solar cells (DSSCs) are designed. Among them, ND02 featuring bulky 4-methoxyphenyl as the additional electron-donating substituents on the NP unit shows a power conversion efficiency as high as 8.30%.
