Technology and design in electronic equipment| Summary: | In this study, we investigate the electrical and photoelectric properties of heterostructures formed by the reactive magnetron sputtering of thin film NiO onto p-CdTe and n-CdTe substrates. The current-voltage characteristics of the heterojunctions were measured at room temperature. The dominating current transport mechanisms through the NiO/n-CdTe and NiO/p-CdTe heterojunctions at the forward biases are generation-recombination and tunnel, at the reverse biases are tunnel current transport mechanisms. The heterojunctions under investigation generate open-circuit voltage Uoc = 0.26 V and short-circuit current Isc = 58.7 μA/cm2 under illumination 80 mW/cm-2.The research results can be used for better understanding of the processes occurring in heterojunctions NiO/ n-CdTe and NiO/p-CdTe, to further improve their properties and parameters. |
