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.

It is well-known that for eucaryotic cells, DNA is located in the karyon and can not penetrate to the cytochylema and the tissue fluid because the cell membrane can act as barriers for DNA transportation. Therefore, the appearance of DNA in cell matrix and the serum can indicate that some diseases have taken place. A main reason for cancer occurrence is the mutation of DNA. It may cause the change of the sequence and expression of cancer suppressor genes.

真核细胞的DNA广泛的存在于细胞核内的染色体上，由于核膜的选择性通透作用，使DNA无法分散到其它细胞的亚器官，加之细胞膜的隔离效果，DNA更难扩散到细胞外基质中，因此细胞外基质中DNA含量的增加往往也会预示某些疾病的发生。
