Influence of Sodium Cations of N3 Dye on the Photovoltaic Performance and Stability of Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin

We report on the effect of substituting the two tetrabutyl ammonium counter ions of the standard N719 dye by sodium ions on the performance and stability of dye-sensitized solar cells (DSCs). The disodium analogue of N719 in conjunction with a non-volatile ...

Thermodynamically stabilized beta-CsPbI3-based perovskite solar cells with efficiencies >18%

Michael Graetzel, Mohammad Ibrahim Dar, Yang Li, Xiaoyan Wang, Ying Yang, Xingyu Gao

Although beta-CsPbl(3) has a bandgap favorable for application in tandem solar cells, depositing and stabilizing beta-CsPbl(3) experimentally has remained a challenge. We obtained highly crystalline beta-CsPbl(3) films with an extended spectral response an ...
