Lamination

Definition

Lamination is a process used to protect and enhance the performance of organic solar cells by applying a protective layer over them. This technique not only serves to shield the sensitive components of the solar cells from environmental factors like moisture, oxygen, and UV light but also improves the mechanical stability and overall lifespan of the devices. Through effective lamination, the efficiency and durability of organic photovoltaics can be significantly increased, making them more viable for commercial applications.
