The efficiency of the welding of solar-cell interconnects is compared with the efficiency of soldering such interconnects, and the cases in which welding may be superior are examined.
All PV cells have both positive and negative layers — it''s the interaction between the two layers that makes the photovoltaic effect work. What distinguishes an N-Type vs. P-Type solar cell is whether the dominant carrier of electricity is positive or negative. N-Type PV cells contain atoms with one more electron than silicon in the outer …
