Abstract

The invention discloses a low-cost graphene film perovskite solar cell and a preparation method thereof, and relates to the field of perovskite solar cells. The low-cost graphene film perovskite solar cell sequentially comprises a substrate, a compact layer, a perovskite layer, a mesoporous layer, a graphene layer, a back electrode, a photoresist layer and an anti-reflection layer from inside to outside. The preparation method of the low-cost graphene film perovskite solar cell comprises five steps of material preparation, bottom layer preparation, middle layer treatment, main layer forming and surface layer treatment. According to the low-cost graphene thin-film perovskite solar cell and the preparation method thereof, the ceramic plate is used as a carrier for forming the graphene thin-film perovskite solar cell, and the forming step of the graphene thin-film perovskite solar cell is completed in the forming groove in the ceramic plate; the transfer operation of the graphene film perovskite solar cell in the process steps is facilitated, and the operability of the process steps is improved.

Description

technical field [0001] The invention relates to the technical field of perovskite solar cells, in particular to a low-cost graphene thin film perovskite solar cell and a preparation method thereof. Background technique [0002] Solar cells have attracted much attention in the industry because of their excellent performance. As a representative of new materials, graphene has a very strong ability to improve solar cells. It can be said that it is a commonly considered object in new battery materials. Graphene is widely used as organic solar cells and dye-sensitized solar cells. Transparent conductive electrodes have also been combined with semiconductors to form Schottky junction photovoltaic devices; and various solar cells based on silicon nanostructures have also been extensively studied and made great progress. [0003] However, the graphene thin film perovskite solar cells currently prepared in the industry have high overall cost and low efficiency due to the complicated...
