In the manufacturing process of amorphous silicon (a-Si:H) solar cells, leakage currents through the pinholes in the a-Si:H film often spoils its performance. We have demonstrated that two electrochemical treatments are effective for stopping the leakage through pinholes. One method is an electrochemical dissolution of the transparent conductive oxide exposed to the pinholes, and another is an electrochemical deposition of insulating materials in the pinholes. These effects have been confirmed by use of intentionally fissured a-Si:H electrodes as well as solar cells showing large leakage currents.
