Main project classification

Solar photovoltaic cell dust-free workshop


The cleanliness of the solar cell production workshop in the purification workshop is generally 10,000, 100,000, and the core part is 1,000.

Production process of purification air conditioning solar cells:

Loading Ultrasonic Cleaning Flocking Deionized Water Cleaning IPA Dehydration Diffusion  Plasma Edge Etching  Dephosphorized Silica Glass  IPA Dehydration  PECVD  Electrode Screen Printing and Drying  Electrode Sintering  Sorting Inspection  Packaging Storage

Among them: diffusion, PECVD, and sintering are the key processes, and each process must formulate strict process requirements and process parameters

Workshop temperature and humidity requirements

Due to the special process technology, the required supply, exhaust, supply, and drainage pipes are large, and the air volume is large, so the floor height of the workshop is 5-6m, and the ceiling height of the workshop is 3.0m. : Pure water machine room, acid drainage treatment tower, organic gas treatment machine room, silane combustion tower, wastewater treatment machine room, cooling water pump room, air conditioning cabinet and ice water main room, compressed air and other special air room. The size of the computer room is selected according to the demand of the machine. The workshop with the main structure of steel structure needs to prepare a load-bearing secondary steel structure for various pipes, and the height of the secondary steel structure is 5-6m.
