摘要
利用射频等离子体增强化学气相沉积工艺(RF-PECVD)制备非晶硅锗薄膜,研究氢稀释率和衬底温度对薄膜光电性能的影响。通过二者的优化制备出光学带隙1.5 eV、光敏性6×104的高质量非晶硅锗薄膜。在此基础上制备出效率为6.65%的非晶硅锗(a-SiGe∶H)单结太阳能电池。
Effects of hydrogen dilution and temperature on the properties of a-SiGe∶ H alloys deposited by plasma-enhanced chemical vapor deposition have been studied.Under the optimum conditions high quality a-SiGe∶ H film with optical bandgap of 1.5 eV and photosensitivity of 6×104 is obtained.With this material a 6.65% conversion efficiency a-SiGe∶ H solar cells is achieved.
