摘要: Schottky diodes and PN junctions were utilized as energy converting structures in ZnO-based betavoltaic batteries, which 0.101121 Ci 63Ni was selected the beta source. The time-related electrical properties obtained using Monte Carlo simulations. For n-type ZnO, Pt/ZnO diode had highest conversion efficiency, Ni/ZnO largest Isc. overall performance of is better than that diodes. lifetimes are longer for other devices, coming close to those junctions. Considering easier fabricate independent p-type semiconductors, offer alternatives PN-junction-based batteries.
