不同周期数的GaInAs/GaAsP多量子阱太阳能电池
GaInAs/GaAsP Multiple Quantum Well Solar Cells with Different Periods
摘要
Abstract
In order to study the GaInAs/GaAsP multiple quantum well solar cells ( MQW-SC ) with different periods, double-junction solar cell samples with different periods quantum well ( QW) and reference sample without QW were grown by metalorganic chemical vapor deposition ( MOCVD) . The crystal quality of the samples was judged by high resolution X-ray diffraction ( HXRD) and high reso-lution transmission electron microscopy ( TEM) . I-V curves and external quantum efficiency ( EQE) of samples were measured under AM0 (1 × ) spectra. Relative to the non-QW sample, the absorption spectra of QW samples extend from 890 nm to 954 nm, the highest external quantum efficiency of the extending spectra achieves 75. 18%, the conversion efficiency increases by 2. 77%. With the in-creased periods of quantum wells structure, the response of the extending spectra and the longer wave-lengths (700-890 nm) in the conventional spectra increase, while in the shorter wavelengths (300-700 nm) the response has a fall. Eventually, the short circuit current and the efficiency of the cells are improved and finally tend to be steady.关键词
