Abstract: The present invention relates to a preparation method for patternization of metal electrodes in silicon solar cells. After disposing an amorphous silicon layer on a silicon substrate processed by diffusion, laser light is projected on the amorphous silicon layer for patternization, and transforming the amorphous silicon with low optical conductivity into polysilicon with high optical conductivity thanks to the recrystallization process of the laser light. Then, after immersing the amorphous silicon layer in plating liquid, metal electrode can be formed accurately at the spots of the amorphous silicon layer patterned by laser light. No external voltage is required; plating reaction is induced by illumination directly.

Instead of a smooth flat surface, a bottom surface of the homogenizer can be a positively curved surface, a conic solid, or a truncated tapered structure.

Thus the precursor stays on surfaces of hepatocytes to provide radioisotope labeling or treatment effect of liver cancers.

This process uses an Evans blue dye having spontaneous fluorescence properties, in combination with the use of a new non-invasive in vivo imaging system (IVIS), to obtain fluorescent signals so as to assess the change in the blood-brain barrier permeability of rodents after a cerebral artery stroke model surgery.

Thereby, the change in the blood-brain barrier permeability of the stroke rat can be completely realized.
