【正文】 sing sequence. Disadvantages: 1. Relatively wider finger width (~150 um), leading to higher shading loss (~10%)。 gradual degradation of printing lines with the wear and tear of the emulsion layer.

Pretty high heighttowidth aspect ratio (as high as 5), leading to lower resistive losses, higher FF。 2. Consuming more wet chemicals, less environmentally friendly.
