This paper investigates the properties of silicon cells(SI)and perovskite solar cells(PSC)under bias condition by using impedance *** parallel resistances R_(p) of SI and PSC are found to decrease with increasing bias,but the capacitance C_(p) shows the opposite *** Rp with C_(p),bias has a greater impact on the C_(p) of both cells.

The primary goal of this paper is to develop methods for investigating equivalent norms and HardyLittlewood-type theorems on Lipschitz-type spaces of analytic and complex-valued harmonic functions. First,we provide characterizations of equivalent norms on these spaces. Furthermore, we establish Hardy-Littlewoodtype theorems for complex-valued harmonic functions. These results improve and extend the main findings of Dyakonov(1997) and Dyakonov(2005). Additionally, we apply the derived equivalent norms and HardyLittlewood-type theorems to the study of composition operators between Lipschitz-type spaces.
