Economical Pt-Free Catalysts for Counter Electrodes of Dye-Sensitized Solar Cells

Michael Graetzel, Ulf Anders Hagfeldt, Liang Wang

Three classes (carbides, nitrides and oxides) of nanoscaled early-transition-metal catalysts have been proposed to replace the expensive Pt catalyst as counter electrodes (CEs) in dye-sensitized solar cells (DSCs). Of these catalysts, Cr3C2, CrN, VC(N), VN ...

Influence of cations of the electrolyte on the performance and stability of dye sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Thomas Moehl, Philippe Wyss

The electrolyte is one of the key components for DSC and its properties have great influence on the photo-conversion efficiency and stability of the devices. Five new low volatile electrolytes containing 3-methoxypropionitrile (MPN) as solvent were prepare ...

High-performance phosphide/carbon counter electrode for both iodide and organic redox couples in dye-sensitized solar cells

Ulf Anders Hagfeldt, Zaiwei Wang, Liang Wang

Mo phosphide (MoP), Ni phosphide (Ni5P4), and C-supported Ni5P4 (Ni5P4/C) were proposed for use as counter electrode (CE) catalysts in dye-sensitized solar cells (DSCs) for the regeneration of both the conventional I3-/I- redox couple and a new org. T2/T- ...
