Over the last years, we have developed a wafer-bonded GaInP/AlGaAs//Si triple-junction solar cell with a recently calibrated conversion efficiency of 34.1% under AM1.5g. This is the highest efficiency of any Si-based 2-terminal tandem device and it shows the potential of this technology to reach significantly higher performances than any single-junction devices.enPhotovoltaikIII-V- und Konzentrator-PhotovoltaikNeuartige Photovoltaik-Technologie621697conference paper
