Embodiment 1

[0039] The first embodiment of the packaging method for a curved battery of the present invention includes the following steps:

[0040] Step 11. Printing of the substrate: the material of the substrate is an aluminum plate. The heated aluminum wire is punched out through a nozzle with a diameter of 0.5mm, and the printing parameters are set to 100% filling to form the target structure model. The printing parameters can be adjusted with different structure models.

[0041] Step 12. Printing of the back electrode layer: the material of the back electrode layer is metallic silver. The silver nanoparticle ink is printed by aerosol (ultrasonic atomization spraying). The ultrasonic atomization device atomizes the ink and sprays it with nitrogen flow. The flow rate is set to 20sccm. After printing, it is dried in an atmosphere of 80 ℃ for 30min to form a silver back electrode. Floor.

[0042] Step 13, printing of the first carrier transport layer: the material of the first carrier...

Description

technical field [0001] The invention belongs to the technical field of photovoltaic cell preparation, and particularly relates to a curved cell and a packaging method thereof. Background technique [0002] Perovskite solar cells are a new type of cell that has emerged in recent years. Due to its continuous improvement in conversion efficiency in a short period of time, the current highest efficiency has exceeded that of crystalline silicon and other thin-film photovoltaic cells, and its commercial application potential is huge. Different from crystalline silicon solar energy, perovskite solar energy has excellent low-light power generation performance, and can also generate electricity under poor irradiation conditions such as cloudy or indoor weak light. The preparation methods of perovskite cells are diverse and can be fabricated on a variety of substrates or deposited on curved substrates. [0003] Perovskite materials are very sensitive to water and oxygen. How to effec...
