Towards Roll-to-Roll Manufacturing of Flexible Perovskite Solar Cells

The scalable slot-die coating methods adopted within TNO enable fabrication of efficient perovskite solar devices with intrinsic stability using various material and layer combinations. Furthermore, several different encapsulation strategies are investigated to define a low-cost route to guarantee long term stable modules. Demonstration of a stable semi-transparent bifacial flexible perovskite module is a step forward on various applications, such as building- and vehicle-integrated PV (BIPV & VIPV) and noise barriers on highways. In this talk, we will give an overview of our story towards realizing a stable, efficient, and bifacial perovskite processed via roll-to-roll slot-die coating technique.
