Abstract

The invention discloses a perovskite solar component and a preparation method thereof. The perovskite solar module includes: a substrate; a transparent conductive oxide layer disposed on at least a part of the surface of the substrate; an electron transport layer disposed on at least a part of the surface of the transparent conductive oxide layer away from the substrate; a photoactive layer disposed on At least a part of the surface of the electron transport layer away from the transparent conductive oxide layer; a hole transport layer, which is arranged on at least a part of the surface of the photoactive layer away from the electron transport layer; an electrode, which is arranged on at least a part of the hole transport layer away from the photoactive layer a portion of the surface; and a barrier layer disposed in the photoactive layer and spacing the photoactive layer from the protrusion of the electrode. The perovskite solar module can effectively solve problems such as shunting caused by direct contact between the photoactive layer and the electrode by setting a barrier layer, and significantly improve the performance of the perovskite solar module.

Description

technical field [0001] The invention relates to the field of photovoltaic devices, in particular to a perovskite solar module and a preparation method thereof. Background technique [0002] Perovskite solar cells are a type of solar cells that are rapidly developing at present, with the characteristics of high efficiency, low cost, and simple preparation. According to the structure, perovskite solar cells are divided into planar structure and mesoporous structure, mainly including transparent electrode, electron transport layer, perovskite light-absorbing material, hole transport layer, counter electrode, etc. After the perovskite material absorbs light, photogenerated electrons and holes are generated, which are transmitted to the electron transport layer and the hole transport layer respectively, and are connected with the external circuit to form a loop to output electric energy. [0003] However, existing perovskite solar cells still need to be improved. Contents of t...
