Kapton® High Performance Flexible Films for Photovoltaic Substrates
Kapton® polyimide film-based substrates enable module manufacturers to realize the potential of roll-to-roll thin film flex CIGS PV on a commercial scale.
DuPont™ Kapton® polyimide films are attractive substrate materials for flexible thin film Copper Indium Gallium Selenide (CIGS) photovoltaic (PV) applications. They offer many desirable characteristics, such as:
- high electrical insulating properties
- and smoothness
In thin film CIGS PV modules, the mechanical properties and dimensional stability of the substrate at elevated deposition temperatures are critical to producing solar cells with maximum efficiency and yields. Kapton® films minimize the stress at the interface during high temperature thin film deposition and processing.
DuPont™ Kapton® polyimide film has set the standard for long-term reliability and high performance in the electronics industry for 50 years. Its superior durability, flexibility and temperature tolerance has also made it an ideal material for use as a thin film flexible CIGS photovoltaic substrate.
