摘要： A perovskite solar battery, including a transparent conductive glass substrate, a hole transport layer, a perovskite light-absorbing layer, an electron transport layer, and an electrode are described. The hole transport layer is a nickel oxide hole transport layer. Simple-substance nickel exists on a contact surface of the hole transport layer in contact with the perovskite light-absorbing layer. On the contact surface of the hole transport layer in contact with the perovskite light-absorbing layer, a ratio between simple-substance nickel and trivalent nickel is 85:15 to 99:1, optionally 90:10 to 99:1, and further optionally 95:5 to 99:1. This application further provides a method for preparing a perovskite solar battery.
