Abstract

The invention discloses a composite encapsulation thin film of an organometallic halide perovskite solar cell and a preparation method thereof, belonging to the technical field of thin film encapsulation. Including the substrate, the organic metal halide perovskite solar cell on the substrate, the organic-inorganic hybrid isolation layer encapsulated on the surface of the perovskite solar cell, and the composite barrier layer encapsulated on the surface of the hybrid isolation layer, the hybrid isolation layer and The composite barrier layer together constitutes the composite packaging film; wherein the hybrid barrier layer is aluminoxane rich in methyl groups or zinc oxide rich in ethyl groups, which is prepared by unsaturated molecular layer deposition method, mainly Play the role of protecting the device from being damaged by the encapsulation process; the composite barrier layer includes at least two inorganic barrier layers prepared by the remote plasma enhanced atomic layer deposition method, and two adjacent layers of inorganic barrier layers prepared by the coating and curing method An organic barrier layer between the barrier layers plays the main role of water and oxygen barrier.

Description

technical field [0001] The invention belongs to the technical field of film encapsulation, and in particular relates to a composite encapsulation film of organic metal halide perovskite solar cells and a preparation method thereof. Background technique [0002] Perovskite solar cells have developed rapidly in recent years due to the advantages of high energy conversion efficiency, low cost, and easy fabrication. However, the most commonly used organometal halide perovskite solar cells are highly sensitive to moisture, and external moisture can cause degradation of the perovskite layer, hole transport layer, and electrode / transport layer, so its practical application requires encapsulation to block water vapor. . [0003] Since the organometal halide perovskite structure and its hole-transporting layer undergo pyrolysis above 60 °C, direct-grown thin-film encapsulation can only be performed at lower temperatures. The current plasma-assisted deposition method can grow high-b...
