A continuity equation for the simulation of the current-voltage curve and the time-dependent properties of dye-sensitized solar cells The Continuity Equation: Conservation of Mass for a Fluid Element which is the same concluded in (4). The derived equation is mass conservation for any flow (compressible or incompressible). In the case of incompressible flows (or almost ”incompressible”-Mach numbers lower than 0.3), from ”incompressibility” we will have: 1 ρ D (ρ) Dt

If the ESD diode is not present, or in the case of continuity tests, if the tester is not connected to the DUT pin, current will not flow through the ESD diode and the

A continuity equation for the simulation of the current-voltage curve and the time-dependent properties of dye-sensitized solar cells This is called the continuity equation. It expresses conservation of mass in the Eulerian frame of reference. 3 We remark that Equation (3.7) is a partial differential equation with four dependent variables: ! and the three components of V. If the velocity were known a priori, the
