Analysis of the impact of parameters on silicon thin films synthesized by HDPCVD

指導教授 : 黃惠良

摘要


We have developed a novel structure which can achieve the efficiency of 17.04%. The structure of the cell is combined of a-Si:H and poly-Si:H of grain size more than 1um with only a pn junction. To fabricate the cell, I will first analyze the parameters to manufacture the poly-Si:H thin film with ICPCVD. In this thesis, I will use N&K, 4-point probe, SEM, XRD, Raman, XRD and Hall measurement to analyze the crystallinity and concentration of thin films. In the experiment, I will fabricate the films in different power densities and pressures. We can get the thin film of about 50nm and crystalline fraction of 74.35% with power density of 0.694 W/cm2. Moreover, n-doped thin film of 3.27E19 cm-3 and p-doped of 8.317E16 cm-3 are obtained. We also propose the formation mechanism of uc-Si thin films.

在之前的工作中,我們已經發展出了一個可以達到效率17.04% 的新結構。這個結構是由非晶矽和晶粒大於一微米的多晶矽所組成,且只有一個PN接面。為了完成這個新結構的太陽電池,我將會先分析ICPCVD的參數以製作出多晶矽薄膜。 在這篇論文裡,我將會用到N&K、四點探針、掃描式電子顯微鏡、拉曼光譜儀、X光繞射儀和霍爾量測,去分析薄膜的結晶度和濃度。在這個實驗裡,我將會在不同的功率密度和壓力下去製作出矽薄膜。 實驗結果顯示當功率達到0.694 W/cm2時,我們可以得到晶粒大小約50奈米,結晶度74.35%。而且,我們也製作出N摻雜濃度為3.27E19 cm-3和P摻雜濃度為8.317E16 cm-3。我們也對微晶矽薄膜提出其形成的機制。
