Formula: ISC
Formula name: ISC (I
SC
)
Units: A
Description: Short circuit current. ISC is the point in I-V data where V = 0.
Formulator entry:
ISC = ABS(AT(ANODEI, FINDD(ANODEV, 0, FIRSTPOS(ANODEV))))
Formula: N
Formula name: N (N(
a
))
Units: 1/cm

Description: Doping density.
Formulator entry:
N = ABS(2/Q/ES/AREA^2/DIFF(INV_C2, DCV_AC))
Simplified equation:
Where:
• N
(a)
= doping density
• q = electron charge (C)
• E
s
= semiconductor permittivity for silicon (F/cm)
• A = area (cm
2
)
• C = measured capacitance (F)
• V = applied voltage (V)
Formula: P
Formula name: P
Units: W
Description: Power.
Formulator entry:
P = CURR*ANODEV
Simplified equation:
P = I x V
Where:
• I = Cell current
• V = Cell voltage
