Lateral Perovskite Single‐Crystal Capacitors for Self‐Powered Photodetection
Abstract: High‐quality perovskite single crystals (SCs) are emerging as promising optoelectronic materials and extensive photodetectors have been reported based on their SC frameworks, however, they are all disabled without applied external bias, and this is an evident obstacle for practical applications. Here, self‐powered photodetection (SPD) of perovskite SCs based on capacitance effects is reported when the capacitor releases its previously stored electric power by discharging operations. The capacitive results are highly in accord with numerical simulations of dielectrics, rather than the common ion migration. The lateral structures show good selectivity for local illuminations and consequently the induced self‐driven photovoltaic effects, but such influences on the SPD can be ignored when the capacitors are charged with sufficient electric power. This work first shows an attempt at achieving SPD in the form of lateral capacitors and may provide another new strategy for self‐powered perovskite devices.
