Mechanism of transient inverse pulse current in hybrid perovskite photodetector induced by proton beam irradiation
Radiation effects on the electrical and optical properties of hybrid perovskite photodetectors (PDs) were evaluated. The photovoltaic conversion efficiency began to decrease when proton fluence reached 1×1013 p/cm/, An abnormal transient inverse pulse current in PDs came out due to the charging and discharging processes in PCBM layers with proton beam induced electron centers. An energy band model integrated with photon-generated carriers' dynamics was established to reveal its physical mechanism.
