Problems solved by technology

In addition, in the domestic perovskite solar cell industry, the roll-to-roll process has been used to print perovskite films to achieve industrialization. However, this process can only be realized on flexible substrates and cannot be applied to the industrialization of rigid conductive glass.

Embodiment 1

[0049] 1. The patterned ITO-coated glass substrate (0.7 inches × 0.7 inches, square resistance ≤ 10Ω / □, light transmittance ≥ 83%) was diluted in detergent, deionized water, acetone and isopropanol (IPA ) in sonication for 20 minutes.

[0050] 2. After drying the pattern-coated ITO in a vacuum oven, it was treated with UV-ozone (Jelight, USA) for 15 minutes, and then transferred to an air-filled electric field treatment automation equipment.

[0051] 3. Preparation of hole transport layer, 2,3,5,6-tetrafluoro-7,7',8,8'-tetracyanodimethyl-p-benzoquinone doped poly[bis(4 -phenyl)(2,4,6-trimethylphenyl)amine] was dissolved in chlorobenzene (CB) to form a 1 mg / ml mixed solution, which was then stirred and heated at 70°C. Before spraying, the prepared solution was filtered with a polytetrafluoroethylene filter (0.45 μm), and then the mixture was sprayed onto the pattern-coated ITO substrate by the first ultrasonic spraying device A, and then the self-heating function of the cerami...

Abstract

The invention relates to the field of perovskite solar cell preparation, and discloses perovskite solar cell automatic production equipment which comprises a first ultrasonic spraying device, a secondultrasonic spraying device, an electric field processing device, a third ultrasonic spraying device, a silk-screen printing device and a conveying device. Wherein the first ultrasonic spraying device, the second ultrasonic spraying device, the electric field processing device, the third ultrasonic spraying device and the silk-screen printing device are sequentially arranged on the conveying device in the transmission direction. According to the invention, a relatively mature spraying technology, a silk-screen printing technology and a variable electric field treatment technology are combinedto form a whole set of production line capable of producing the perovskite solar cell on the rigid conductive substrate, so that the industrial preparation process of the perovskite device treated bythe variable electric field is truly realized, and the conductive glass sheet is put into the production line; and the seamless connection of the finished perovskite device is realized.

Description

technical field [0001] The invention relates to the field of preparation of perovskite solar cells, in particular to a preparation process for the industrialization of electric field-treated perovskite solar cells. Background technique [0002] In the past 10 years, the efficiency of metal halide perovskite solar cells (PSC) has been continuously improved, and it is close to the current mainstream crystalline silicon solar cells in industrialization. However, due to its own organic-inorganic hybrid characteristics, the interstitial organic matter that makes up the regular octahedron of the perovskite structure is prone to decomposition when exposed to high temperature, ultraviolet, water and oxygen atmospheres, which limits its industrial application in solar cells. In order to solve the stability problem of perovskite solar cells, researchers have adopted various packaging processes for devices from the inside to the outside. By wrapping the upper and lower layers of the p...
