- pvdeg.letid.convert_i_to_v(tau, na, current, wafer_thickness, srv, temperature=298.15, e_mobility=0.15, xp=2.4e-07, nc=2.8e+25, nv=1.6e+25, e_g=1.79444e-19)[source]#
Return voltage given lifetime and applied current, and cell parameters
- Parameters:
tau (numeric) – Carrier lifetime [s].
na (numeric) – Doping density [m^-3].
current (numeric) – applied current [A].
wafer_thickness (numeric) – Wafer thickness [m].
srv (numeric) – Surface recombination velocity [m/s].
temperature (numeric, default 298.15) – Cell temperature [K]
e_mobility (numeric, default 0.15) – electron mobility [m^2/V-s].
xp (numeric, default 0.00000024) – width of the depletion region [m]. Treated as fixed width, as it is very small compared to the bulk, so injection-dependent variations will have very small effects.
nc (numeric, default 2.8e25) – density of states of the conduction band [m^-3]
nv (numeric, default 1.6e25) – density of states of the valence band [m^-3]
e_g (numeric, default 1.79444e-19) – bandgap of silicon [J].
- Returns:
voltage (numeric) – cell voltage [V]
