- Abstract
- Super-flexible bis(trifluoromethanesulfonyl)-amide (TFSA)-doped graphene transparent conducting electrode (GR TCE)-based FAPbI(3-x)Br(x) perovskite solar cells with 18.9% power conversion efficiency (PCE) for a rigid device and 18.3% for a flexible one are demonstrated because the TFSA-doped GR TCE reveals high conductivity and high transmittance. The unencapsulated TFSA-doped GR TCE-based cell maintained similar to 95% of its initial PCE under a continuous light soaking of 1 Sun at 60 degrees C/30% relative humidity for 1000 h. In addition, the TFSA-doped GR TCE-based flexible perovskite solar cells show excellent bending stabilities, maintaining PCEs of similar to 85, similar to 75, and similar to 35% of their original values after 5000 bending cycles, at R = 12, 8, and 4 mm, respectively.
