EN Flexible perovskite solar cells (f-PSCs) offer attractive commercial prospects in the near future, enabled by new value propositions, such as mechanical flexibility, or high specific powers. The long-term reliability of these devices requires appropriate encapsulation to prevent degradation caused by environmental factors. Here, a lamination protocol is developed, incorporating adhesive materials, barrier foils, and edge sealants, which results in a robust device hermitization. By applying the developed procedure to three different perovskite solar cell configurations (p-i-n with carbon, p-i-n with silver, and n-i with carbon), fabricated with large active areas (1 cm2), the universality of this approach is demonstrated. The best devices preserved over 85% of the initial performance after a sequence of accelerated aging tests based on industry standards (compliant with the IEC 61215 and IEC 61646) comprised of 1400 h of damp heat, 50 thermal cycles, and 10 cycles of the humidity-freeze test.
