Abstract
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.

A light guide tape for using on bus bars of solar panels comprising:
- a flexible transparent substrate with a plurality of light guide micro-structures on the side of incident sunlight;
- and
- an adhesive layer for adhering the light guide tape to the bus bars of the solar panels;
- wherein each of the light guide micro-structures is in a prism shape with a reflective surface for reflecting the incident sunlight, wherein an included angle between each of the reflective surfaces and the flexible transparent substrate is at 30 degree to 60 degree to transfer the incident sunlight to outside areas of the bus bars by single reflecting.
