· Safety Precautions: Space solar cells contain harmful substances (arsenic and phosphorus). Handle them carefully with protective gloves (e.g., latex) to avoid health risks such as ingestion, inhalation of dust, or skin contact. Wash hands thoroughly if skin contact occurs.xqRShanghai YIM Machinery and Equipment Co.ltd

· Breakage Protocol: In the event of breakage, clean up contaminated areas promptly.xqRShanghai YIM Machinery and Equipment Co.ltd

· Handling Tools: Use vacuum tweezers for handling the cells.xqRShanghai YIM Machinery and Equipment Co.ltd

· Environmental Protection: Keep cells dry and protect from humidity to prevent oxidation and corrosion of materials (e.g., Ge substrate, metallization, semiconductor layers, ARC).xqRShanghai YIM Machinery and Equipment Co.ltd

· Storage: Store and transport in dry conditions. Avoid outgassing from the storage package.xqRShanghai YIM Machinery and Equipment Co.ltd

nProcessing:xqRShanghai YIM Machinery and Equipment Co.ltd

· Interconnector Material: Use gold or silver for the front side interconnectors.xqRShanghai YIM Machinery and Equipment Co.ltd

· Soldering: Use silver-saturated solder (Sn96.5/Ag3.5 or other suitable variants). Do not exceed a soldering temperature of 300°C for brief periods (approx. 1 minute) to avoid damage to the metallization.xqRShanghai YIM Machinery and Equipment Co.ltd

· Mounting: Use flexible glue when attaching secondary optics or a cover glass to avoid mechanical strain on the cell and metal fingers.xqRShanghai YIM Machinery and Equipment Co.ltd

· Cleaning: Clean the cell using ethanol or isopropyl alcohol under dimmed light conditions. Avoid solvents that, in combination with light or voltage, could cause dendrite growth due to silver electro-migration.xqRShanghai YIM Machinery and Equipment Co.ltd

· Mechanical Handling: Avoid applying shear forces to the metal grid and smearing metal over the edges of the cell, as this could result in short-circuits.xqRShanghai YIM Machinery and Equipment Co.ltd

· Electrical Protection: Ensure solar cells are protected from electrical discharge during all processes.xqRShanghai YIM Machinery and Equipment Co.ltd

nOperation:xqRShanghai YIM Machinery and Equipment Co.ltd

· Temperature Limit: Do not exceed a maximum operating temperature of 150°C.xqRShanghai YIM Machinery and Equipment Co.ltd

· Open-Circuit Operation: Avoid operating the cell in an open-circuit condition, as it risks overheating and damaging the cell. Uneven illumination should not cause the temperature difference to exceed a factor of 2.xqRShanghai YIM Machinery and Equipment Co.ltd

· Bypass Diodes: Each solar cell in a module must be equipped with a bypass diode to prevent damage from current or voltage spikes.xqRShanghai YIM Machinery and Equipment Co.ltd

· Avoid Spikes: Avoid current and voltage spikes during operation, connection, and disconnection to the grid.xqRShanghai YIM Machinery and Equipment Co.ltd
