Solar cell manufacturing facilities and research labs use wet processing equipment to etch and clean solar cell silicon wafers.
The wet processing systems are available as inline as well as batch versions according to customer requirements. The modular design provides flexibility for both manual and fully automated operation. The systems can be easily integrated into every production process.
MicroTech Systems provides equipment solutions for solar cell manufacturing - wet process equipment. A major benefit is the low water consumption in their solar thin film production tool. Modules are available for clean, develop, etch and ultrasonics process steps. See our news release for more information and download the whitepaper.
The modular batch wet processing system offer a wide range of process options. The machine concept fulfills current and future requirements of capacity, flexibility and reliability for mass production.
The SILEX III wet processing system was specially designed for larger production volumes. With this mass production system about 550 MW annual capacity are possible for Heterojunction cell manufacturing.
Such roughness can reduce the life span of the solar cell and impacts performance. By polishing the rear side of the cell and the edges in an etching bath, internal light reflection is improved and a higher efficiency cell can be manufactured. Ozone Pre-Cleaning The cutting of silicon wafers with a wire saw uses a slurry applied to the wires.
