Abstract

Disclosed is a solar battery adopting a multifunctional transparent electrode. The solar battery comprises a tin oxide thin film layer which is used as an electrode layer and an electron transport layer as well, a metal electrode layer, and a perovskite active layer arranged between the tin oxide thin film layer and the metal electrode layer. The solar battery also comprises a hole transport layerarranged between the perovskite active layer and the metal electrode layer. The invention also provides a preparation method of the solar battery adopting the multifunctional transparent electrode. By taking one layer of multifunctional tin oxide nanomaterial thin film as the transparent electrode layer and the electron transport layer (electron extraction layer) in the perovskite battery structure, the perovskite solar battery is established on the basis, so that the battery structure is simplified and the preparation cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of solar cell devices, in particular to a solar cell using a multifunctional transparent electrode and a preparation method thereof. Background technique [0002] Since the discovery of organic-inorganic perovskite solar cells in 2009, their photoelectric conversion efficiency has increased from an initial 3.8% to the current 22.1%. Its photoelectric conversion efficiency has approached or surpassed traditional polysilicon, cadmium telluride and copper indium gallium selenide, etc. The development rate of perovskite cells is unmatched by any type of solar cell. At present, high-efficiency perovskite cells use mesoporous TiO 2 structure, and the mesoporous TiO used in this structure 2 It must be sintered at high temperature, which will increase the cost in the actual production process. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object ...
