Fullerene-based electrode interlayers for bandgap tunable organometal perovskite metal–semiconductor–metal photodetectors |
(a) Transient response of photodetectors with different fullerene-based interfacial layers to a 500-nm incident light with a light intensity of 2 mW/cm2 at 5 V. (b) Photocurrent rise and fall time of the devices. |
