Photoelectric Detection

Metal halide perovskite is one type of optoelectronic materials with rapid development in recent years, which is widely used in solar cells, LEDs and photodetectors. Among them, photodetector is expected to be the first area to be applied in products. Perovskite photodetectors are generally divided into photoconductive type and p-i-n photodiode type. They have some common problems worthy of study, such as improving the photo responsivity (or sensitivity) of perovskite photodetectors, reducing the dark current and noise current of devices, developing the graphic process of detectors, implementing pixel application, etc. Our research fields mainly focus on improving sensitivity of detectors, developing new phototransistor devices and fabricating graphical perovskite array.
