LIGHT GUIDE TAPE

摘要

A light guide tape for using on bus bars of solar panels to increase the utilization efficiency of the incident sunlight is disclosed. The light guide tape includes a flexible transparent substrate with a plurality of light guide micro-structures on the side of the incident sunlight, and an adhesive layer. The incident sunlight shielded by the bus bars of the solar cells can transfer to generating regions of both sides of the bus bars through the plurality of light guide micro-structures to increase the utilization efficiency of the incident sunlight.
