Abstract

A solution-processed photodetector based on organic?inorganic hybrid perovskites (OIHP) with a sub-nanosecond response time at zero-bias operation was reported. PTAA dissolved in toluene was spun on clean ITO substrates at a speed of 5000rpm. The film was then annealed at 100°C for 10 min. Lead iodine (PbI2) and methylammonium iodide (MAI) were dissolved in dimethylformamide and 2-propanol with concentrations of 630 and 65 mg mL-1, respectively. The PbI2 solution was spun on a PTAA layer at 6000 rpm for 35 s. Then the PbI2 film was transferred onto a hot plate at 90°C for quick drying. The light intensity was calibrated using a silicon diode. The temperature dependence of the response speed was measured by the Linkam Scientific Instruments LNP95 cooling system.This is the first time a low-cost solution-processed photodetector has been shown to meet the requirements for application in very-high-performance scientific equipment.
