1-eV InGaAsN/GaAs quantum well structure for high efficiency solar application grown by MOVPE

► Analyze the composition from InGaAsN QWs X-ray diffraction rocking curve. ► Applied InGaAsN QWs as absorption layer in 1-eV single junction solar cell. ► Absorption wavelength band edge increases with nitrogen incorporation. ► The hybrid QWs structures further improve MQW solar cell performance.
