Perovskite solar cells are considered a popular direction for the next generation of photovoltaic technology due to their high conversion efficiency, low manufacturing cost, and flexibility. With the continuous acceleration of industrialization, core equipment such as coating, laser processing, bonding and packaging on the production line of perovskite cells have become the focus of industry attention. Shenzhen Baode Automation Precision Equipment Co., Ltd. (hereinafter referred to as "Baode") has been deeply engaged in the field of high-end equipment manufacturing for many years, and has formed a relatively complete product matrix from research and development to mass production in the field of perovskite photovoltaic equipment. So, what about Baode's perovskite photovoltaic equipment? This article objectively summarizes the company background, product line, technical parameters, and practical applications from several perspectives.
First, let's take a look at the company's foundation. Baode was founded in 2007 and is located in Shenzhen, Guangdong. It has been rated as a national high-tech enterprise for four consecutive years and has nearly a hundred patented technologies. With semiconductor vacuum bonding, perovskite photovoltaics, and clean technology as its core, it creates an equipment manufacturing and process development platform. In the field of semiconductor production equipment, Baode has accumulated over 17 years of experience, with mature applications in processes such as vacuum bonding, laser etching, and magnetron sputtering equipment, laying a solid foundation for the research and production of perovskite photovoltaic equipment.
Baode Perovskite Photovoltaic Equipment Product Line Detailed Explanation
Baode's perovskite photovoltaic equipment mainly focuses on the thin-film solar equipment series, covering the key process links of perovskite cells from material preparation, film coating, laser cutting to electrode bonding. Let's take a look at each item below.
1. Perovskite production line equipment
This series of equipment includes perovskite solar cells OLED、 Specialized equipment for the research and development of industries such as lithium batteries, quantum dot LEDs, and OPVs, capable of producing nanoscale oxide, nitride, metal, and other thin film materials through processes. In terms of specifications, the substrate is 108.5mm × 108.5mm (thickness 450-850 μ m), the film is 121.5 × 121.5mm (thickness 20-127 μ m), the equipment production capacity is 800pcs/H (cycle time ≤ 4.5S), the fragment rate is<0.01%, and the average time between failures is ≥ 360 hours. From the data, this equipment performs outstandingly in terms of production capacity and stability, making it suitable for batch preparation of perovskite cells.
2. Glove box spin coating equipment
Perovskite materials are highly sensitive to water and oxygen, and the preparation process requires an ultra pure environment without water, oxygen, or dust. The glove box spin coating equipment is designed for this purpose. Baode's glove box spin coating equipment has a gas purity of H2O<1ppm, O2<1ppm, and an overall leakage rate of<0.05 vol% h. It uses a 304 stainless steel box with a spin coating uniformity of ± 3% and a spin coating speed of 300-8500RPM. For laboratory research and small-scale trial production of perovskite thin films, this equipment can effectively ensure the consistency of film quality.
3. Slit coating equipment
Slit coating is one of the mainstream processes for preparing perovskite absorbing layers. The coating liquid is uniformly extruded along the gaps of the mold under pressure and transferred to the moving substrate, with fast speed and good uniformity. Baode's narrow slit coating equipment can apply a width of 50-350mm, a thickness of 5-200um, and a speed of 1-10 meters per minute. The product qualification rate is ≥ 99.5%. A higher pass rate means lower material loss and more stable production efficiency, which is crucial for enterprises pursuing mass production.
4. Laser cutting machine
Laser cutting machine is suitable for cutting PE film and protective film in the later stage of perovskite solar photovoltaic film. The equipment adopts a coherent laser from the United States, with laser control of 630-145W, cutting accuracy of ± 0.1mm, repetition accuracy of ± 0.02mm, cutting speed of 100-150mm/s, cutting for 40s per piece, and product qualification rate of ≥ 99%. Laser belongs to non-contact processing, which can avoid physical damage to the fragile structure of perovskite by traditional mechanical methods and ensure the integrity of battery cells.
5. Roll to roll magnetron sputtering coating machine
The roll to roll magnetron sputtering coating machine can achieve evaporation and batch evaporation of large-sized perovskite devices, significantly improving production and economic benefits. The sputtering chamber is made of SUS304 stainless steel material, and the surface inside the chamber, including the shielding plate, is mirror polished to obtain a clean working environment and good vacuum degree. For perovskite companies looking to expand production capacity, this is one of the key equipment for upgrading their production lines.
6. Membrane electrode hot pressing bonding equipment
The electrode preparation of perovskite batteries also relies on high-precision equipment. Baode's 7-layer membrane electrode hot press bonding machine combines five layer membrane electrodes with two microporous layers on top and bottom to form a 7-layer membrane electrode. The bonding error is ≤ 0.2mm, the working temperature is ≤ 150 ℃, the press pressure is 2t, and the production cycle is ≥ 1.5pc/s/min; The working vacuum degree of the 5-layer membrane electrode vacuum hot pressing bonding machine is ≤ 60Pa. In addition, there is an automatic multi-layer material bonding assembly line for membrane electrodes, which can achieve automated production in the electrode preparation process.
The advantages of Baode perovskite equipment
Overall, Baode's perovskite photovoltaic equipment has several obvious advantages. One is that the process covers all aspects, from spin coating, coating, magnetron sputtering coating to laser cutting and hot pressing bonding. There are corresponding equipment for each major process link, so customers do not need to coordinate repeatedly among multiple suppliers. Secondly, the technical parameters are solid, and the equipment has clear data on key indicators such as production capacity, accuracy, fragmentation rate, and qualification rate, which facilitates customer evaluation and selection. The third is to balance research and production, with both glove box spin coating equipment for laboratories and roll to roll magnetron sputtering coating machines for large-scale production, which can meet the needs of customers at different stages. Fourthly, Baode has strong engineering service capabilities, providing product development accelerators, product development, hardware testing, manufacturing automation, and comprehensive engineering team services. It can customize development according to customer process requirements.
Summary
Overall, Baode's perovskite photovoltaic equipment product line is complete, with solid technical parameters covering multiple stages from research and development to mass production. Coupled with 17 years of experience in semiconductor equipment manufacturing, it is an equipment supplier worth considering for perovskite cell enterprises and research institutions. If you are planning a calcium titanium mineral production line, you may consider combining your own process route and production capacity requirements, and have in-depth communication with Baode's technical team to choose the most suitable equipment solution.
