9 ）的提高；先沉积氮化硅薄膜再氢等离子体处理能得到更好的钝化效果。 - The writer also elaborates the working principles of solar cell and various factors that may lead to bad conversion efficiency of solar cell , emphasizes on three thin film solar cells ( amorphous silicon thin film solar cell , poly silicon thin film solar cell , cuinsea thin film solar cell ) , analyzes their structure , photovoltaic effect , producing techniques , and conversion efficiency etc . , and discusses how to reduce the effects of sw in solar cell and how to improve the conversion efficiency
阐述了太阳电池的工作原理，论述了影响太阳电池转换效率的因素，并重点介绍了当前研究比较深入的三种热点薄膜太阳电池：非晶硅薄膜太阳电池( a - si ) ；多晶硅( poly - si )薄膜太阳电池：铜铟锡( cis )薄膜太阳电池。分析了它们的结构、光伏效应、制备工艺、转换效率等，探讨了如何减小太阳电池的光致衰退效应和提高薄膜太阳电池的转换效率的方法。 - Both hydrogen plasma and sinx thin film can effectively enhance the short circuit current density of mono and poly silicon solar cells , which cause the improvement of the absolute transfer efficiency about 0 . 5 % ~ 2 . 9 % . depositing sinx thin film followed by hydrogen plasma treatment will result in better passivation effect . the thickness of sinx thin film will decrease and the refractive index will increase after annealing
经过薄膜后退火处理发现，氮化硅薄膜经热处理后厚度降低，折射率升高，但温度达到1000oc时折射率急剧降低；沉积氨化硅薄膜后400oc退火可以促进氢扩散，提高钝化效果；超过400oc后氢开始逸失，晶体硅材料中的少子寿命急剧下降； rtp （快速热处理）处理所导致氢的逸失比常规退火处理显著。
