Electrode splicing-type carbon-based perovskite solar cell manufacturing method

Abstract

The invention discloses an electrode splicing-type carbon-based perovskite solar cell manufacturing method. The method comprises steps: conductive glass with an edge conductive film removed is acquired through mechanical cutting; multiple pieces of conductive glass are spliced on a glass substrate through an adhesive layer; a hole blocking layer and a perovskite light absorbing layer are sequentially deposited on a predetermined area on the upper surface of the conductive glass as a cell slice photoanode; the upper surface of the conductive glass is provided with a conductive carbon film as a cell slice photocathode; the conductive carbon film is connected with the perovskite light absorbing layer; and the cell slice photocathode is connected with the conductive glass of a photoanode of a former cell slice or a latter cell slice. Cutting of the conductive glass is carried out in the mechanical cutting mode, the edge conductive film is removed during a cutting process, a photoanode and an adjacent photocathode are insulated, electrode splicing is then carried out, the problem of difficulty of control caused by wet etching on the conductive glass is avoided, the process difficulty is reduced, the photoanode and the photocathode can be manufactured independently, and the cell manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of perovskite solar cells, in particular to a method for preparing electrode spliced ​​carbon-based perovskite solar cells. Background technique [0002] In recent years, with the continuous progress of human society, the demand for energy has continued to increase. The increase in proven reserves of traditional fossil energy is lower than the consumption, resulting in an energy crisis, and the extensive use of fossil energy has caused environmental pollution, resulting in energy shortages and environmental pollution. These two problems have seriously threatened the development of society and economy, and have become the focus of attention of all countries in the world. Therefore, all countries are focusing on exploring and building their own new energy sources, and solar cells, as a clean and renewable energy source, can solve the two major problems of energy crisis and environmental pollution at the same t...

Problems solved by technology

However, if the etching time is not properly controlled, over-etching will easily occur, resulting in an increase in the sheet resistance of the conductive glass and a series of problems such as affecting the photoelectric performance of the battery.
