Ulbrich Solar Technologies has begun high-volume production of a PV ribbon product called Light-Capturing Ribbon (LCR).
LCR is produced and sold under a license agreement with 1366 Technologies. The grooved interconnect ribbon's design enables module makers to achieve approximately 2% or more module power output gain, according to Ulbrich. The improved efficiency is achieved by recapturing the light that normally leaves the module after striking the surface of standard ribbon.
Ulbrich says it has also developed the capability to selectively apply solder only on the bottom (flat) side of the ribbon. This capability gives customers the ability to achieve the benefits of LCR while continuing to use solder connections on one side.
