Description	Journal: Nanotechnology We first report highly-flexible perovskite photodiodes using AuCl3-doped multilayer-graphene transparent conducting electrodes. The doping effect of the AuCl3 is more effective at number of layers (Ln) = 1 and 2 than 3 and 4, as analyzed by Raman scattering and sheet resistance. The photodiodes optimized at Ln = 2 exhibit 105 photo-/dark-current ratio, 0.4 AW-1 responsivity, 80 % external quantum efficiency, 5.3 x 1010 cm Hz1/2/W detectivity, 90 dB linear dynamic range, and ~1.1 μs response time. In addition, the photodiodes show excellent bending stabilities, maintaining the responsivity at about 70% of its initial value even after 1000 bending cycles at a bending curvature of 4 mm.
