Kapton® PV9100 Series

Kapton® PV9100 series polyimide films are flexible substrates for thin film photovoltaic (PV) applications

Kapton® polyimide film is widely used as a dielectric substrate for its high temperature resistance, self extinguishing burn characteristics, toughness and flexibility.

DuPont™ Kapton® polyimide films are in commercial use as well as in evaluation as substrates in thin film a-Si and CIGS photovoltaic applications, in which the stiffness and dimensional stability at elevated deposition temperatures are critical to producing solar cells with maximum efficiency and yields. The low coefficient of thermal expansion (CTE) of Kapton® PV9100 series polyimide films minimizes the stress at the interface during high temperature thin film deposition and processing.

 Kapton® has more than 45 years of proven performance as the material of choice in applications involving temperature extremes and harsh environments.
