One-step hydrothermal synthesis of ZnS-CoS microcomposite as low cost counter electrode for dye-sensitized solar cells

- First ever study of ZnS-CoS microcomposite as counter electrode in dye-sensitized solar cells.
- ZnS-CoS microcomposite shows remarkably enhanced electrocatalytic activity compared with pristine ZnS.
- Dependence of device efficiency on Co/Zn molar ratio is investigated.
- The best performing ZnS-CoS counter electrode (6.11%) enhances the device efficiency by over 10 times compared with pristine ZnS electrodes.
