Problems solved by technology
[0002] Due to the gradual shortage of energy sources, the utilization of green energy such as solar energy is gradually increasing. However, the photoelectric conversion efficiency of commercially available solar cells is only about 10% to 25%, which is not enough to greatly replace the use of existing energy sources. Therefore, how to increase The utilization efficiency of solar energy has always been the goal of people's efforts; and in the existing solar panels, there must be a collector bus to collect the current converted from sunlight, and the more and wider the collector bus is, the less likely it is to make the current It is consumed in the conduction process, but generally the collector busbar is made of metal material, which cannot allow light to penetrate. Therefore, the larger the area occupied by the collector busbar, the more it reduces the entry of sunlight, which affects the solar panel's response to the incident sun. light utilization

Abstract
The invention relates to a light guide adhesive tape applied to a current collection bus of a solar panel. The light guide adhesive tape is provided with a transparent base material layer and an adhesive layer, wherein the transparent base material layer is arranged on a sunlight incident side and provided with a plurality of light guide microstructures; and the adhesive layer is positioned on the other side of the transparent base material layer opposite to the light guide microstructures to adhere the light guide adhesive tape to the solar panel. According to the light guide adhesive tape provided by the invention, sunlight which is originally shot into the current collection bus and shaded is transmitted to power generation zones on two sides of the current collection bus through the plurality of light guide microstructures, so that the utilization efficiency of the sunlight is improved.
Description
technical field [0001] The invention relates to a light-conducting adhesive tape used on a collector bus of a solar panel. The light-conducting adhesive tape can transmit sunlight irradiated on the collector bus to a power generation area next to the collector bus. Background technique [0002] Due to the gradual shortage of energy sources, the utilization of green energy such as solar energy is gradually increasing. However, the photoelectric conversion efficiency of commercially available solar cells is only about 10% to 25%, which is not enough to greatly replace the use of existing energy sources. Therefore, how to increase The utilization efficiency of solar energy has always been the goal of people's efforts; and in the existing solar panels, there must be a collector bus to collect the current converted from sunlight, and the more and wider the collector bus is, the less likely it is to make the current It is consumed in the conduction process, but generally the colle...
