Charge recombination resistance

WebNov 17, 2024 · These resistance values are obtained from the plot of the junction resistance, R J, versus the voltage, V; R J = d V d J. Massive shunt resistance is required to decrease the leakage of current via cells (e.g., pinholes), apart from suppressing the recombination of charge carriers at the device interface [31,32,33]. WebMay 26, 2024 · From the fitting results, the recombination resistance ( Rrec) was 44.47, 98.92, and 189.67 Ωcm 2 for the CdS/CdSe, CdS/CdSe/ZnS (AQ), and CdS/CdSe/ZnS …

Understanding the Factors that Affect Aging in Lithium-ion

WebThe surface recombination process that models the charge behavior at the interface acts effectively like a current source or sink. Electrons and holes interact with impurity trap states at the surface, and recombine. Therefore, a surface recombination rate specifies a Neumann (or derivative) boundary condition on the charge density. WebTransient photovoltage (TPV) measurements on g-C 3 N 4, MoS 2 and MCZ-7.5 composite were applied to study the surficial charge transfer and recombination rates. [35] As shown in Fig. 4 d, the photovoltage intensity followed the trend of MCZ-x > MoS 2 > g-C 3 N 4 , showing the strong role of MoS 2 as a strong light absorption unit. [36]
