太陽(yáng)能光伏組件生產(chǎn)線(xiàn)車(chē)間環(huán)境要求嚴格,需從潔凈度、溫濕度、靜電防護、氣流組織、照明與通風(fēng)、材料選擇、環(huán)保與安全等多維度進(jìn)行控制,以保障組件性能和生產(chǎn)效率。以下是具體要求:
The environmental requirements for solar photovoltaic module production line workshops are strict, requiring control from multiple dimensions such as cleanliness, temperature and humidity, electrostatic protection, air flow organization, lighting and ventilation, material selection, environmental protection, and safety to ensure component performance and production efficiency. The specific requirements are as follows:
I. Cleanliness Requirements
空氣潔凈度等級:根據光伏組件生產(chǎn)的不同環(huán)節,車(chē)間空氣潔凈度等級有所不同。例如,普通組件生產(chǎn)車(chē)間要求空氣潔凈度達到十萬(wàn)級別,即空氣中含塵濃度(0.5μm 顆粒大?。┎怀^(guò) 10 萬(wàn)個(gè) / 立方米;而電池生產(chǎn)車(chē)間等關(guān)鍵環(huán)節則需要更高的空氣潔凈度水平,可能達到千級或萬(wàn)級。
Air cleanliness level: According to different links in photovoltaic module production, the air cleanliness level of the workshop varies. For example, ordinary module production workshops require air cleanliness to reach 100,000 class, that is, the dust concentration in the air (0.5μm particle size) does not exceed 100,000 particles per cubic meter; while key links such as battery production workshops require a higher air cleanliness level, which may reach 1,000 class or 10,000 class.
潔凈區劃分:根據工藝流程,合理劃分潔凈區、緩沖區、輔助區等區域,減少交叉污染,提高生產(chǎn)效率。
Clean area division: According to the process flow, reasonably divide clean areas, buffer zones, auxiliary areas, etc., to reduce cross-contamination and improve production efficiency.
人員與物料管理:?jiǎn)T工進(jìn)出車(chē)間需穿戴無(wú)塵服、口罩及手套,并進(jìn)行風(fēng)淋處理,以去除身上的塵埃顆粒。物料進(jìn)入車(chē)間前也需經(jīng)過(guò)清潔處理,確保無(wú)外界污染源帶入。
Personnel and material management: Employees entering and leaving the workshop must wear clean clothes, masks, and gloves, and undergo air shower treatment to remove dust particles on their bodies. Materials must also be cleaned before entering the workshop to ensure no external pollution sources are brought in.
II. Temperature and Humidity Requirements
溫度控制:車(chē)間溫度一般控制在 20℃—26℃之間,精密工藝(如光刻、薄膜沉積)需控制在 22℃±0.5℃,甚至 ±0.1℃以避免晶圓熱脹冷縮導致的套刻誤差。
Temperature control: The workshop temperature is generally controlled between 20℃ and 26℃. Precision processes (such as photolithography and thin film deposition) need to be controlled at 22℃±0.5℃, or even ±0.1℃ to avoid overlay errors caused by thermal expansion and contraction of the wafer.
濕度控制:車(chē)間濕度通常設定為 40%—60% RH,半導體制造環(huán)節需精準至 50%±3% RH,以抑制靜電產(chǎn)生并防止水分子與光刻膠發(fā)生化學(xué)反應。
Humidity control: The workshop humidity is usually set to 40%—60% RH, and the semiconductor manufacturing link needs to be precise to 50%±3% RH to suppress static electricity generation and prevent chemical reactions between water molecules and photoresist.
波動(dòng)率限制:溫濕度變化率需≤5%/h,避免因環(huán)境突變引發(fā)材料形變或工藝缺陷。
Fluctuation rate limit: The temperature and humidity change rate must be ≤5%/h to avoid material deformation or process defects caused by sudden environmental changes.
III. Electrostatic Protection Requirements
靜電消除器:配置靜電消除器,預防靜電對光伏電子元器件的損害。
Static eliminator: Equip static eliminators to prevent static electricity from damaging photovoltaic electronic components.
接地系統:建立完善的接地系統,確保設備、工作臺及人員接地良好,防止靜電積累。
Grounding system: Establish a sound grounding system to ensure good grounding of equipment, workbenches, and personnel, preventing static electricity accumulation.
防靜電材料:車(chē)間內使用防靜電地板、防靜電工作臺等防靜電材料,減少靜電產(chǎn)生。
Anti-static materials: Use anti-static materials such as anti-static floors and anti-static workbenches in the workshop to reduce static electricity generation.
IV. Air Flow Organization Requirements
單向流或亂流設計:采用科學(xué)合理的氣流組織方式,如單向流或亂流潔凈室設計,確??諝鉂崈舳染鶆蚍植?,并有效排除微粒和污染物。
Unidirectional or turbulent flow design: Adopt scientific and reasonable air flow organization methods, such as unidirectional or turbulent flow clean room design, to ensure uniform distribution of air cleanliness and effectively remove particles and pollutants.
送風(fēng)量與換氣次數:根據車(chē)間潔凈度等級和面積大小,確定合適的送風(fēng)量和換氣次數。例如,300 平方米的車(chē)間,吊頂高度為 2.5 米,萬(wàn)級潔凈室送風(fēng)量設置 300×2.5×30=22500m3/h(換氣次數≥25 次 /h);十萬(wàn)級潔凈室送風(fēng)量設置 300×2.5×20=15000m3/h(換氣次數≥15 次 /h)。
Air supply volume and air change rate: Determine the appropriate air supply volume and air change rate according to the workshop cleanliness level and area. For example, for a 300-square-meter workshop with a ceiling height of 2.5 meters, the air supply volume of a 10,000-class clean room is set to 300×2.5×30=22500m3/h (air change rate ≥25 times/h); the air supply volume of a 100,000-class clean room is set to 300×2.5×20=15000m3/h (air change rate ≥15 times/h).
V. Lighting and Ventilation Requirements
照明系統:采用高效節能的 LED 照明系統,既滿(mǎn)足生產(chǎn)需求又減少能耗。照明亮度需根據車(chē)間具體需求進(jìn)行調整,確保操作區域光線(xiàn)充足。
Lighting system: Adopt high-efficiency and energy-saving LED lighting systems to meet production needs and reduce energy consumption. The lighting brightness needs to be adjusted according to the specific needs of the workshop to ensure sufficient light in the operating area.
通風(fēng)系統:確保車(chē)間內空氣流通,減少塵埃積聚,同時(shí)排出有害氣體,保持良好的工作環(huán)境。通風(fēng)系統需與空調系統協(xié)同設計,確保溫濕度控制效果。
Ventilation system: Ensure air circulation in the workshop to reduce dust accumulation, while exhausting harmful gases to maintain a good working environment. The ventilation system needs to be designed in coordination with the air conditioning system to ensure the effect of temperature and humidity control.

Floor materials should be wear-resistant, non-slip, and easy to clean, such as epoxy floors or PVC floors. Wall materials should have dust-proof, anti-static, and corrosion-resistant properties, and can be selected from antibacterial coatings or stainless steel plates.
表面處理:對選用的材料進(jìn)行必要的表面處理,如拋光、噴涂防靜電涂層等,以減少塵埃附著(zhù)和靜電產(chǎn)生。
Surface treatment: Perform necessary surface treatments on the selected materials, such as polishing and spraying anti-static coatings, to reduce dust adhesion and static electricity generation.
