Abstract
Photovoltaic power converters have been fabricated in the InGaAsP material system. The devices are optimized to convert monochromatic light at 1.06 µm. An extremely high conversion efficiency of 43% with antireflection coating has been achieved. The best device has an open circuit voltage of 0.73 V and a short circuit current of 4 mA when illuminating with 4.85 mW 1.06 µm Nd-Yag laser radiation. A saturation current density as low as 10-9A/cm2has been obtained. The fill factor of the cell is 0.72.
