Abstract
Provided are a perovskite betavoltaic-photovoltaic battery. The battery includes a first electrode, a first charge transport layer, a perovskite layer, a second charge transport layer, and a second electrode in sequence. The first electrode is a transparent electrode. The first charge transport layer is an electron transport layer and the second charge transport layer is a hole transport layer, or, the first charge transport layer is a hole transport layer and the second charge transport layer is an electron transport layer. The perovskite layer is doped with a fluorescent substance. At least one of the first electrode, the first charge transport layer, the second charge transport layer, or the second electrode is radioactive. When the first electrode and/or the second electrode is radioactive, the first electrode and/or the second electrode is an irradiated electrode formed by compounding a radioactive source and a conductor material.
