| CdS is unfortunately not suitable for overall water splitting since prolonged irradiation of its suspensions leads to photocorrosion. |
| The careful and exhaustive testing of such properties as conductivity and photocorrosion in a material that nature doesn't even use for her success. |
| A big hurdle in our solar to hydrogen conversion process is the stabilization of the electrodes against photocorrosion. |
| However, the sufficiently negative conduction band potential of CdS makes it photoinstability, which is usually due to photocorrosion. |
| We recently developed an efficient and low cost protective polymer coating that allows for good electrical conductivity as well as preventing photocorrosion. |
| Limitations include the expense of the required materials, electrode instability against photocorrosion, and poor solar-to-hydrogen. |
