Perovskite solar cell module encapsulation method

Abstract

This invention discloses a method for encapsulating a perovskite solar cell module. Before laminating the solar cell module, a pressure clamp is used to apply pressure to the adhesive between the solar cell substrate and the encapsulation element, causing the adhesive to adhere to the solar cell substrate and the encapsulation element. The pressure clamp eliminates air bubbles between the adhesive and the solar cell substrate and improves the yield of perovskite solar cell module encapsulation.
