The influence of Ni-Ru alloy on battery testing and solar cell applications in the study of electrochemical properties is mainly reflected in its excellent electrical properties and efficient electron/hole transport capacity. Ni-Ru alloy electrodes show remarkable advantages in the application of quantum dot solar cells (QDSC).
Ni-ru alloy electrodes have lower charge transfer resistance (Rct) than pure metal electrodes (such as pure Ni or pure Ru), which indicates better electrical performance. Specifically, the Rct of the Ni-Ru alloy counterelectrode is 9.4Ω⋅cm−2, which is lower than the 42.81Ω⋅cm−2 of the pure Ru counterelectrode and 136Ω⋅cm−2 of the pure Ni counterelectrode. The low charge transfer resistance helps facilitate the transfer of charge, ensuring that the electrons produced by the light excitation have enough time to reach the electrode before recombining, thereby improving the overall performance of the battery.
Ni-Ru alloy electrode assembly of QDSC shows better photoelectric performance. For example, the short-circuit photocurrent (Jsc) of QDSC based on Ni-Ru alloy electrode is 5.88 mA⋅cm−2, the open circuit photovoltage (Voc) is 0.64 V, the filling factor (FF) is 0.52, and the energy conversion efficiency reaches 1.96%, which is higher than the efficiency of pure Ru (1.65%) or pure Ni (0.87%) assembled devices. This result shows that the Ni-Ru alloy electrode not only improves the photoelectric conversion efficiency, but also enhances the electron transport efficiency, because the Ni-Ru alloy nanoparticles are in closer contact with the FTO substrate.
The preparation method of Ni-Ru alloy electrode also has an important influence on its performance. The Ni-Ru nanoalloy electrode prepared by hydrothermal method and in-situ growth method can achieve the co-deposition of Ni and Ru, so as to form a uniform and compact electrode structure. This structure not only helps to improve the electrochemical activity of the electrode, but also enhances its application effect in quantum dot solar cells.
The influence of Ni-Ru alloy on battery testing and solar cell applications in the study of electrochemical characteristics is mainly reflected in its excellent electrical properties and efficient electron/hole transport capacity, which makes Ni-Ru alloy electrodes show higher photoelectric conversion efficiency and better overall performance in quantum dot solar cells.
