Description

Technical Field

[0001] The utility model relates to the technical field of packaging devices, in particular to a full-color micro-layer roll-to-roll normal-temperature packaging device. Background Technique

[0002] With the increasing global demand for renewable energy, solar photovoltaic technology, as a clean and sustainable energy solution, has become one of the key technologies for the energy structure transformation in many countries and regions. In this context, the design and performance of full-color optoelectronic functional materials not only directly affect the energy conversion efficiency but also play an important role in improving building aesthetics and urban environment. Especially for full-color optoelectronic functional materials, with their colorful and flexible design features, they are increasingly favored by consumers in fields such as engineering lighting and landmark building displays, becoming a major highlight of modern urban architecture.

[0003] The existing full-color optoelectronic functional material packaging technology uses high-molecular materials such as PVB and EVA for high-temperature lamination. The lamination principle is to apply a certain pressure on the outer surface of each layer of the component and tightly press each layer together under the heating state. The above process usually consists of four major systems: a heating system, a vacuum system, a pneumatic system, and a control system. The working process of a specific laminator is as follows: The component to be laminated enters the laminator and is heated, the EVA melts, and at the same time, the vacuum is pumped to discharge the gas volatilized from the chamber and the component, and then pressure is applied to crosslink and cure the PVB and EVA. This process has high energy consumption and requires a relatively high temperature, and is not suitable for flexible thin-film solar cells that require low-temperature packaging.

[0004] Therefore, those skilled in the art provide a full-color micro-layer roll-to-roll normal-temperature packaging device to solve the problems raised in the above background technique. Content of the Utility Model
