pvdeg.letid.calc_voc_from_tau

pvdeg.letid.calc_voc_from_tau(tau, wafer_thickness, srv_rear, jsc, temperature, na=7.2e+21)

Return solar cell open-circuit voltage (Voc), given lifetime and other device parameters

Parameters:

• tau (numeric) – Carrier lifetime [us].

• wafer_thickness (numeric) – Wafer thickness [um].

• srv_rear (numeric) – Rear surface recombination velocity [cm/s].

• jsc (numeric) – Short-circuit current density [mA/cm^2].

• temperature (numeric) – Temperature [C].

• na (numeric, default 7.2e21) – Doping density [m^-3]. Default value corresponds to ~2 Ω-cm boron-doped c-Si.

Returns:

numeric – Device Voc [V].
