Abstract :
The cell design and manufacturing process for the high efficiency thin silicon space solar cells (call NRS/LBSF cell) were finalized and their characteristics were qualified. The 100 μn NRS/LBSF cells showed efficiencies of maximum 18.5% and average 18.0%. After electron irradiation of 1E+15e/cm2, the NRS/LBSF cell showed about 1.2 times higher output power than the conventional 200 μm BSR cell
