Моделювання фотодіодної структури на основі гетеропереходу ZnO/Si

In this work, a self-powered photodetector based on a bulk ZnO/Si p–n heterojunction is numerically investigated and analyzed using the Solar Cell Capacitance Simulator in One Dimension (SCAPS-1D). The energy band diagram, electron-hole generation and recombination rates, current-voltage (J–V) chara...

Description
Summary:In this work, a self-powered photodetector based on a bulk ZnO/Si p–n heterojunction is numerically investigated and analyzed using the Solar Cell Capacitance Simulator in One Dimension (SCAPS-1D). The energy band diagram, electron-hole generation and recombination rates, current-voltage (J–V) characteristics, spectral photosensitivity response, and specific detectivity are examined. To optimize photodetector performance, the effects of absorber layer thickness, shallow acceptor and donor ­densities, and defect density were systematically studied. Various electron transport parameters of ZnO were also considered. The responsivity and specific detectivity of the simulated photodetector are 0.23 A/W and 1.1·1010 Jones, respectively.
