AI Technical Summary

Technical Problem

When photovoltaic modules operate in high-temperature environments, their photoelectric conversion efficiency decreases. There is limited research on the introduction of phase change materials in existing technologies, which leads to increased module temperature and affects power generation efficiency.

Method used

Photovoltaic films containing phase change materials are used. By introducing phase change materials such as paraffin and block polymers into the film, the module temperature is controlled within the range of 30-70℃. The latent heat absorption effect of the phase change materials is utilized to suppress temperature rise and improve power generation efficiency.

Benefits of technology

It effectively suppresses the temperature rise of photovoltaic modules, improves photoelectric conversion efficiency, reduces cross-linking risks during processing, and increases production efficiency and capacity.

Abstract

The application provides a high-gain photovoltaic adhesive film containing a phase change material and belongs to the technical field of photovoltaic adhesive films. The high-gain photovoltaic adhesive film containing the phase change material is characterized in that the adhesive film contains the following components in parts by weight: 100 parts of a base resin, 1-20 parts of a phase change material, 0.1-2 parts of an initiator, 0.01-1.5 parts of an assistant initiator, 0.1-5 parts of a binder and 0.01-0.6 parts of an anti-aging agent. The phase change material in the adhesive film can absorb heat when the photovoltaic module works in a high-temperature environment, so that the working temperature of the photovoltaic module is inhibited from rising, and the power generation efficiency of the photovoltaic module is further improved.
