A kind of preparation method of perovskite solar cell module

Abstract

The invention relates to a method for preparing a perovskite solar cell module. FTO is separated by a laser scribing line P1 with a distance of 1 cm; the distance between P1 and P1 is 100 μm, and a stainless steel wire with a diameter of 100 μm is used to block the FTO, and the method of thermal spraying is used to prepare titanium oxide. Or tin oxide, remove the steel wire to form the isolation line P2-1; use the co-evaporation method to prepare the lead iodide / cesium iodide film, put the lead iodide / cesium iodide film into the vacuum chamber, heat the FAI powder, FAI steam and Lead iodide / cesium iodide thin film reaction to form CsxFA1‑xPbI3 perovskite thin film; then spray hole transport layer material, use laser along P2‑1 to draw separation line P2‑2; thermally evaporate gold, use laser distance P2‑2 The isolation line P3 is drawn at 100 μm, and the perovskite solar cell module is obtained by packaging. The invention uses stainless steel wires to cover FTO, thermal sprays to prepare titanium oxide or tin oxide films, uses the isolation line P2-1 formed after removing the steel wires, solves the problem of effective series connection between perovskite solar cells, and has high implementation efficiency.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a method for preparing a perovskite solar cell component. Background technique [0002] The development of perovskite solar cells is very rapid, and the reports of small-area perovskite solar cells have reached nearly 22.1%. However, these battery preparation processes all use spin-coating or anti-solvent methods, which cannot be mass-produced. [0003] The practical application of perovskite solar cells requires multiple cells to be connected in series to form a large-area module structure. However, the commonly used electron transport materials such as titanium oxide and tin oxide are very similar to the material properties of transparent electrodes, so the traditional laser scribing method cannot Scrape off the electron transport material without damaging the transparent electrode. Although the use of organic electron transport materials can solve this problem, the organi...
