A preparation method of electrode splicing carbon-based perovskite solar cells

Abstract

The invention discloses a method for preparing an electrode splicing carbon-based perovskite solar cell, which comprises: obtaining conductive glass with edge conductive film removed by mechanical cutting; splicing a plurality of conductive glasses on a glass substrate through an adhesive layer; A hole blocking layer and a perovskite light-absorbing layer are sequentially deposited on the predetermined area of ​​the upper surface of the glass as the photoanode of the cell; a conductive carbon film is set on the upper surface of the conductive glass as the photocathode of the cell; the conductive carbon film and the perovskite The light-absorbing layer of the battery is connected, and the photocathode of the cell is connected with the conductive glass of the photoanode of the adjacent previous cell or the next cell. The conductive glass is cut by mechanical cutting. During the cutting process, the conductive film on the edge is removed, the adjacent photoanode and photocathode are insulated, and then the electrodes are spliced ​​to avoid the difficult control problem caused by wet etching conductive glass. , which reduces the difficulty of the process, and the photoanode and photocathode can be produced independently, which reduces the cost of cell production.

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.
