Abstract
Calculation has been performed to predict the ultimate conversion efficiency of various split-spectrum multiple-solar cell systems. Based on this analysis, a triple-cell system is designed and fabricated, in which the solar radiation is divided by multi-layered filters into three beams of different spectral bands; the beams are then converted separately by GaAs-, Si-, and Ge-cell. The total conversion efficiency of 22.7% is achieved. The factors determining the efficiency are examined to clarify possible methods of attaining higher efficiencies.Keywords
