Abstract

We report the photosensitive properties of CdS thin films doped with boron at high doping levels. Boron-doped CdS thin films were successfully prepared through the chemical bath deposition (CBD) method. The photosensitive properties of the boron-doped CdS thin films were significantly affected by the molar ratio of boric acid (H ₃BO ₃) to cadmium acetate (CdAc ₂) (0.001, 0.1, 0.15, and 0.25) and by NH ₃ concentration (7 and 14 M). As the H ₃BO ₃/CdAc ₂ molar ratio increased, dark sheet resistance rapidly increased, and the boron-doped CdS thin film exhibited the highest room temperature photosensitivity (∼1×10 ⁶ at 0.15-0.25 H ₃BO ₃/CdAc ₂ molar ratio). The photosensitive properties of the boron-doped CdS thin films were much higher than those previously reported in boron-doped CdS systems.
