Problems solved by technology

[0002] With the rapid development of the solar photovoltaic industry, more and more solar photovoltaic applications have emerged as the times require. Now solar photovoltaic applications are no longer limited to power station projects and solar street lights, but have entered various industries, such as advertising, agriculture, decoration, etc., but Most of the existing processes are used in the way of external splicing. Even if some modular products are used, there are many defects in the production: on the one hand, there is no complete production method, on the other hand, the application is relatively simple; and a solar photovoltaic module and LED integrated packaging module-PV-LED integrated double-glass module can solve the above problems, but PV-LED integrated double-glass module packaging requires multiple components to be assembled, so there are bubbles during packaging, LED lamp bead packaging is damaged, Problems such as offset and arrangement seriously affect the quality of components

Abstract

The present invention discloses a PV-LED integrated double-glass module encapsulation method. A solar photovoltaic double-glass module and a LED product are perfectly combined, two sheets of glass and an insulation layer are composed, and the back glass of the LED is encapsulated; an interlayer lays solar cells, and Sn-coating copper strip arranged between the solar cells forms a composite layer which is in parallel with and collects the whole component of a lead terminal; and coating is adopted to bond between layers to form a whole module. The PV-LED integrated double-glass module encapsulation method is applied to fields of the photovoltaic industry, the application problem of the combination of a solar photovoltaic module and a LED is solved, and the problems of bubbles in the process of the PV-LED integrated double-glass module manufacture and the damage, the migration and the assignment of the LED lamp bead encapsulation are effectively solved. The PV-LED integrated double-glass module may be modularized and integrated and may take the largest advantage for markets.
