镀层

The spectroscopic and electrochemical studies suggest the energy structure of this class complex can be easily controlled by modification. With the introduction of electron-donating arylamino groups, the obtained complexes show intense and continuous absorption bands in the region of 250-550nm with strong metal-to-ligand charge transfer dπ(Pt →π* transitions (ε~ 2×104 dm3 · mol-1 · cm-1). Complexes involving the construction of D-π-A type systems also display continuous absorption bands in the region of 400-750nm, rising from the overlapping effect of MLCT and LL'CT bands.

其中，芳胺及其二聚体类修饰基团的引入，使其配合物MLCT吸收谱带的摩尔吸光系数增加，并在250～550nm范围内形成了强的连续吸收；具有D-π-A结构的配合物，由于MLCT吸收谱带和LL'CT吸收谱带的协同效应，导致在400～750nm范围内形成连续吸收；得到了从绿光到深红光的磷光发射系列配合物，并采用真空蒸镀的方法获到了外量子效率分别为5.7%和5.0%的橙光和橙红光多层电致发光器件。

In our experimental results, we have transferred the GaAs solar cells from GaAs substrates onto the mirror-coated copper substrates with the base layer thickness of 1.5 μm. The photovoltaic performance of the orginal GaAs solar cell on a GaAs substrate was also measured. Under AM1.5G and without anti-reflective coatings conditions, it is found that the Jsc can increase from 12.6 mA/cm2 to 13.82 mA/cm2, while the conversion efficiency can improve from 7.91% to 8.53%. As a result, the enhanced Jsc and η data of the GaAs solar cells can be contributed by the AuGe/Au mirror between the GaAs solar cell and copper substrate.

在实验验证方面，本实验室将砷化镓太阳电池由砷化镓基板转移至铜基板上，在基极厚度1.5 μm、AM 1.5G、以及元件未披覆抗反射膜的条件下，短路电流密度可由12.6 mA/cm2提升至13.82 mA/cm2，增加9.7%，而转换效率则可由7.91%提升为8.53%，这结果显示当砷化镓太阳电池基极底部镀有金属反射层时，的确能适度地提升太阳电池的短路电流密度及转换效率。

The Au/AuGe(88/12)/Au back-contact metal structure was deposited on the GaAs substrate using an electron-beam evaporator. Various post thermal treatments were employed including conventional furnace and rapid thermal annealing. It was found that the outer Au layer thickness and furnace annealing temperature had large effects on the specific contact resistance.

在实验中我们在砷化镓基板背面进行蒸镀背金结构，而此背金结构是由三层金属所组成，分别为金/锗(12%)金(88%)/金，我们控制最外层金的厚度来量测与观察特徵接触电阻的大小，同时改变炉管加热的温度与快速热退火系统做比较，背金结构之元素分布比较可由欧杰电子分析得到，而扫描式电子显微镜可分析其两者之间的表面形貌差异。
