CBD grown ZnO-based gas sensors and dye-sensitized solar cells

Chemical bath deposition (CBD) is used for depositing different metal chalcogenide and oxide thin films through an ion-by-ion or by adsorption of colloidal particles from the solution on the substrate. In this review, we focused our intension on CBD zinc oxide (ZnO) films synthesis with different proposed deposition mechanisms and their integration into gas sensor and dye-sensitized solar cells. Due to the use of CBD ZnO films in gas sensors first time by our group, we presented film thickness, gas concentration and palladium sensitizer effect on the gas sensing properties in details. Review on CBD grown ZnO implication in dye-sensitized solar cells is also discussed in brief.
