AI Technical Summary

Technical Problem

Traditional reflective films are thick due to their multi-layered structure, which is not conducive to the assembly of smaller gaps, and the multi-layered bonding structure causes light energy attenuation.

Method used

The reflective film adopts a thin structure design, which includes an adhesive film layer, a microstructure layer and a reflective layer arranged in sequence. By optimizing the interlayer structure, a single adhesive film layer without PET substrate is formed. The microstructure and reflective layer are directly prepared on the adhesive film layer, reducing the number of layers and improving optical performance.

Benefits of technology

This has resulted in a significant reduction in the overall thickness of reflective film products, improved optical performance, enhanced light energy utilization, and suitability for assembly in smaller gaps.

Abstract

This utility model discloses a reflective film and a solar panel, relating to the field of solar photovoltaic power generation technology. The reflective film includes: an adhesive film layer; a microstructure layer disposed on the adhesive film layer; and a reflective layer disposed on the microstructure layer. The reflective layer, the microstructure layer, and the adhesive film layer are sequentially arranged from top to bottom to form a thin-structured reflective film. This utility model solves the problem that traditional reflective films use a multi-layer structure, resulting in a thicker reflective film product, which is not conducive to assembly in smaller gaps, and the multi-layer bonding structure also causes light energy attenuation.
