Abstract

One or more embodiments of the present specification provide a perovskite solar cell comprising, in order from bottom to top, a substrate on which transparent conductive glass is deposited, a magnesium-doped titanium dioxide electron transport layer, a perovskite absorption layer, a hole transport layer, and an electrode, the Mg element is used as an effective doping agent to be introduced into acompact TiO2 electron transport layer in a simple mode, and the planar perovskite solar cell is constructed. Mg doping can enable the Fermi level of TiO2 to move upwards, increase the free carrier concentration of the film and reduce the defect state concentration of the deep energy level. Therefore, the resistance of TiO2 is reduced, and the fill factor and the photoelectric conversion efficiencyof the whole cell device are improved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of solar cells, in particular to a perovskite solar cell and a preparation method thereof. Background technique [0002] In recent years, the photoelectric conversion efficiency of perovskite solar cells has been rapidly improved, and has been regarded as the most promising photovoltaic technology. In perovskite solar cells, titanium dioxide (TiO 2 ) is the most widely used electron transport material, depending on the preparation method and structure, TiO 2 The electron transport layer is divided into a mesoporous structure and a planar structure. The planar structure can further simplify the preparation process and reduce the preparation cost, which is more conducive to commercialization; [0003] But TiO 2 The conductivity of the electron transport layer is average, and there are many surface defect states, which easily cause the recombination and accumulation of carriers...
