Highly efficient counter electrode in dye-sensitized solar cells (DSSCs)

What is it about?

In this work, oxygen vacancies were created to activate tungsten trioxide (WO3) as a highly efficient counter electrode in dye-sensitized solar cells (DSSCs). The levels of oxygen vacancies (OVs) in WO3 were finely formed and tuned by doping with different weight percentages of urea and annealing in a N2 environment at 470 °C.

Why is it important?

The urea doped WO3 significantly improved the electrocatalytic behavior in the iodide–triiodide electrolyte
