Foster: Light-transmitting films can be used in HJT and perovskite tandem components.

Foster stated on the interactive platform that the company is the world's largest supplier of light-transmitting films. Light-transmitting films are able to convert ultraviolet light into visible light, and can be used on the front of solar cells to increase the power generation of photovoltaic modules. They can be used in HJT, BC, perovskite, and perovskite layer stack modules. Currently, they are more widely used in HJT modules, but are still in the trial stage in perovskite layer stack modules due to the technological development of perovskite modules. As a global leader in photovoltaic film, the company offers a wide variety of film products and conducts extensive technical and supply cooperation with various types of component customers worldwide.
