  • Q Handling and storage

    Handling and storage
    SPACE solar cells contain harmful substances arsenic (As) and phosphorus (P) and shall be handled with care using appropriate hand protection (eg. latex gloves). Human consumption of cells, broken pieces and inhalation of dust may results in health reasons and should be avoided. In case of direct skin contact, hand washing is strongly recommended.
    In case of the cell breakage, cleaning up of contaminated parts is recommended.The use vacuum tweezers for handling is recommended.The cell shall be protected from humidity and moisture, which may cause oxidation and corrosion of Ge substrate and other parts of the solar cell (metallization, III/Vsemiconductor materials, ARC).
    The cells shall be transported and stored in dry conditions. Outgasing of any substances from the storage package has to be avoided.
  • Q Processing

    The recommended material for front side interconnectors is gold or silver.
    Soldering process requires the use silver-saturated solder to avoid dissolution of the cell metallisation. The soldering process temperature should not exceed 300°C for short time (about 1 min).The recommended solder material should be Sn96.5/Ag3.5 or any other suitable silversaturated solder. For mounting a secondary optics or a cover glass on top of the cell, flexible glue is required to avoid mechanical strain to the cell and, especially, to the metal fingers.
    For cleaning purposes, ethanol or isopropyl alcohol are allowed at dimed light conditions.Different solvents in combination with light or induced voltage could stimulate dendrite growth on the metallisation, which caused by silver electro-migration. Shearing force to the metal finger grid shall be avoided.
    Smearing metal over the cell edge is not allowed due to risk of the short-circuit.
    At any process- and operation condition, solar cells shall be protected from electrical discharge.
  • Q Operation

    The cell shall not overcome a maximum operation temperature of 150°C.
    The cell operation at open-circuit condition is not allowed. There is a serious risk to overheat the cell or its local areas which could damage the cell. An inhomogeneous illumination could cause local overheating. The inhomogeneity of the cell illumination shall not exceed factor 2.
    In a module, each solar cell has to be protected by a bypass diode.Current and/or voltage spikes during operation, connection and disconnection to the grid should be avoided
