制备了CdSe0.4Te0.6（摩尔基）和CdTe的梯度吸收器件。CdCl2处理时间、沉积后CdCl2退火时间以及CdSeTe和CdTe层厚度均有变化。对制备的器件进行了光致发光和电学测量。结果表明，CdSeTe和CdTe的厚度对器件的整体效率至关重要。在其余工艺参数不变的情况下，在0.5µm CdSeTe和3µm CdTe衬底上制备的器件效率为20.14%。我们报告了学术界和研究机构中最高的设备效率。
Graded absorbers devices with with CdSe0.4Te0.6 (molar basis) and CdTe were fabricated. CdCl2 treatment time, post-deposition CdCl2 anneal time and thicknesses of CdSeTe and CdTe layers were varied. Photoluminescence and electrical measurements were performed on the fabricated devices. Results revealed that the individual thicknesses of CdSeTe and CdTe is critical to overall efficiency of the devices. Device fabricated on substrate with 0.5 µm CdSeTe, 3 µm CdTe with rest of process parameters kept unchanged, produced an efficiency of 20.14%. We report highest device efficiency among academia and research institutions.
