Load current in Solar cell Solution

Follow our step by step solution on how to calculate Load current in Solar cell?

FIRST Step Consider the formula

I = I sc - (I o \cdot (e^{\frac{[Charge-e] \cdot V}{m \cdot [BoltZ] \cdot T}} - 1))

Next Step Substitute values of Variables

∴

I = 80A - (4E-6A \cdot (e^{\frac{[Charge-e] \cdot 0.15V}{1.4 \cdot [BoltZ] \cdot 300K}} - 1))

Next Step Substitute values of Constants

∴

I = 80A - (4E-6A \cdot (e^{\frac{1.6E-19C \cdot 0.15V}{1.4 \cdot 1.4E-23J/K \cdot 300K}} - 1))

Next Step Prepare to Evaluate

∴

I = 80 - (4E-6 \cdot (e^{\frac{1.6E-19 \cdot 0.15}{1.4 \cdot 1.4E-23 \cdot 300}} - 1))

Next Step Evaluate

∴

I = 79.9997516627406A

LAST Step Rounding Answer

∴

I = 79.9998A
