On photo numerals designate:
1. Car engine silicon gasket.
2. Plastic spacer thickness 2mm.
3. Air pressure equalization tube (part of medical needle).
4. Bypass diode SS34 (SS32 is preferred).
5. Output wire fixing. Because any node is impossible in so small space (2mm), wire fixed by bend in half and sewing thread tied.
6. stainless frame (sheet thickness 0.6mm).

Connecting wire: red wire - 0.75mm2,
green wire - 0.35mm2,
tabbing wire - 0.2mm2

After cell is tabbed, I cover the front side of the solar cell protective coating "plastic 70".
