AI Technical Summary

Problems solved by technology

In photovoltaic windows, photovoltaic roofs and photovoltaic curtain walls that require thermal insulation, the commonly used hollow battery modules are hollow glass composed of a layer of laminated glass containing battery packs and another single piece of glass. Although the thermal insulation performance meets the The requirements of buildings, but the photovoltaic cells will generate a certain amount of self-heating during the power generation process, and the temperature of the air in the hollow layer will increase, resulting in a decrease in the power generation efficiency of the cells. At the same time, the insulating glass is also prone to self-explosion.

Its security and reliability cannot meet the requirements of practical applications
