The express Improvement of perovskite solar cells(PSC) has made them the highest Interest to studied for PV(Photovoltaics) and application in renewable energy. Here in we report on PSC applied on photoelectrolysis of water. Basically, it is easily decomposed by moisture and water. Thus, when it applied to water splitting. It is Important to protect device for stability of PSC. In this work, we demonstrate a method that improved stability of PSC during oxygen evolution in water. Field’s metal, a fusible In-Bi-Sn alloy, is used efficiently as a protection. Because of this it prevents the electrolyte from attacking the perovskite layer, and at the same time stably operates the reaction that the generated electrons transfer to oxygen evolution reaction(OER). Also it is deposited the Ni layer on the device by electrodeposition method. Ni as a catalyst for OER and it is abundant. As a result, the photo-electrode shows remarkable stability and performance in neutral and alkaline solutions, Under the continuous illumination(AM1.5G).
