    摘要: 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.

    摘要: A perovskite solar cell, a preparation method therefor and a power consuming device are provided. In some embodiments, the perovskite solar cell of the present application has, in order, a back electrode, a hole transport layer, an interface passivation layer, a perovskite layer, an interface passivation layer, an electron transport layer, and conductive glass, wherein the HOMO energy level of an interface between the perovskite layer and the interface passivation layer is 0.01-0.4 eV, and the energy band gap between the HOMO energy level and the LUMO energy level is 0.01-0.4 eV; and the interface passivation layer contains: an organic amine salt of a biphenyl compound and/or an organic amine salt of an acene compound. In the perovskite solar cell according to the present application, by passivating the perovskite layer therein with an organic amine salt of a biphenyl compound or acene compound, the VBM of the perovskite layer is improved, facilitating the extraction of holes, and the transport efficiency of carriers is improved, so that the efficiency and stability of the perovskite solar cell can be greatly improved.
