An effective interconnection band for a photovoltaic module and manufacturing method thereof; the effective interconnection band comprises a conductive baseband (1); the enveloping outline of the conductive baseband (1) is a flat wire material, and at least one of the two wide surfaces of the conductive baseband is a heterogeneous wide surface; the heterogeneous wide surface is provided with a plurality of recesses (2) thereon; coupling platforms (3) exist between neighboring recesses (2); and the coupling platforms (3) are rough planes having a surface profile arithmetic average deviation Ra in a range of 0.25 μm - 5 μm. Part of the reflected light of the interconnection band surface is reflected via the glass-air interface of the module back to the surface of a battery piece for multiplexing, increasing the power of the module, reasonably adjusting the yield property of the interconnection band, and improving the weather-resistant property of the module; in addition, a micropore accumulation mechanism for molten solder/ conductive adhesive glue is built on the contact surface of the interconnection band and the battery without affecting the above capabilities, improving the bonding of the interconnection band and the battery piece. |
