"Tabbing ribbon (flat wire) is a very specialized interconnect for photovoltaic modules. It is made of a copper ribbon or flat wire which is coated in solder. The solder protects the surface of the copper from oxidation and provides a layer of solder to form a solder joint. These solder-coated copper strips are used to channel current from the top and bottom of solar cells (tabbing/stringing) or to collect the electricity from these strings (bussing).
You can think of tabbing wire as roads which travel across a solar cell, and bus ribbon as the highways that connect and tie them together. The main difference: bus ribbon is a bit wider, and sometimes thicker than tabbing ribbon. Bus ribbon is larger in cross-section because it has more electrical current to carry.

BLOCKING DIODES
Diodes placed in series with cells or modules can perform another function that of blocking reverses leakage current backwards through the modules. There are two situations where blocking diodes can help prevent the phenomenon.
• Blocking reverse flow of current from the battery through the module at night.
In battery charging systems, the module potential drops to zero at night, and the battery could discharge all night backwards through the module. This would not be harmful to the module, but would result in loss of precious energy from the battery bank. Diodes placed in the circuit between the module and the battery can block any nighttime leakage flow.
• Blocking reverse flow down damaged modules from parallel modules during the day.
Blocking diodes placed at the head of separate series wired strings in high voltage systems can perform yet another function during daylight conditions. If one string be comes severely shaded, or if there is a short circuit in one of the modules, the blocking diode prevents the other strings from loosing current backwards down the shaded or damaged string. The shaded or damaged string is “isolated” from the others, and more current is sent on to the load. In this configuration, the blocking diodes are sometimes called “isolation diodes”.
