Abstract :
The authors describe a mathematical parametric study of converters used to convert laser radiation to electricity for space-based laser power systems. Two different lasers, the 1.06 mu m Nd laser and the 1.315 mu m iodine laser, are used in the vertical junction converter. The calculated efficiency is 50% for a 100-junction Si photovoltaic converter when used with a Nd laser. The calculated efficiency for a 1000-junction Ga0.53In0.47As photovoltaic converter is 43% when used with an iodine laser.
