Abstract
- Abstract Hybrid structure optoelectronic devices can bring hope to the design of new-generation functional nanodevices because they can combine hybrid structure nanomaterials with flexible and transparent substrates to maximize device miniaturization and usability. Here, we prepared a highly efficient flexible photodetector based on a SnO 2 /CH 3 NH 3 PbI 3 hybrid structure. The photodetector exhibits a very wide spectral response range and fast response speeds. The response speeds is shorter than 0.4 s under 388 nm laser irradiations at 3 V. Moreover, the device demonstrates surprising flexibility under different bending degrees and excellent mechanical stability after many extreme bending cycles. Hence, the great potential properties of inorganic/perovskite hybrid materials will make it into a promising building block in flexible optoelectronics. Graphical abstract The low-cost fabrication of SnO 2 /CH 3 NH 3 PbI 3 hybrid structure flexible photodetector exhibits good flexibility and stability. Image 1 [ABSTRACT FROM AUTHOR]
