Abstract
Methylammonium lead halide perovskites have received substantial attention in photoelectric research communities, because of excellent optoelectronic properties, including long electron-hole diffusion distance, large absorption coefficients in the UV–Vis spectral region, low-cost, solution-based processing and low binding energy of exciton. Many records, such as efficiencies have been kept by these perovskite solar cells. However, other excellent properties, such as ultrafast properties have not been studies intensively. Here vertical field effect phototransistors (VFEpTs) based on methylammonium lead halide perovskites were design and fabricated. VFEpTs exhibit high performances including an ultrafast photoresponse time (less than 20 ns) and a high photoresponsivity (~ 10 mAW−1). The methylammonium lead halide perovskite vertical phototransistors open path on ultrafast devices with low cost solution fabrication process, but high level performances.
