A perovskite solar cell and a method for manufacturing the same are provided. The method for manufacturing the perovskite solar cell includes steps as follows. A compact layer having a thickness of 20 nm to 120 nm is sputtered to be formed on a transparent conductive electrode, and the compact layer includes titanium dioxide.
A rough layer having a thickness of 20 nm to 30 nm is sputtered to be formed on the compact layer, and the rough layer includes titanium dioxide. A perovskite layer is disposed on the rough layer. A hole transport layer is disposed on the perovskite layer. A back electrode is disposed on the hole transport layer. |
