Space Solar Cell Assembly SSTL has the capability to interconnect and glass bare solar cells in preparation for lay down of the solar panel. SSTL uses an ultrasonic welding technique for the connection of silver or gold coated inter-connector to the front busbar of the cell. Ultrasonic welding of interconnect to bare cell The cells are then glassed using space qualified glass, followed by retesting and grouping in the appropriate current class. Research and Development As part of our on-going R & D we are developing the capability to laydown on large area advanced lightweight CFRP panels of up to 2m dimension using large area high efficiency triple junction gallium arsenide solar cells with a conversion efficiency of up to 29%. We are also in close contact with the developments of the European and USA cell manufacturers for the early use of their four and five junction high efficiency cells (>33%) on our panels as they reach qualification status….
