1. What is Maximum Power Output of Cell?

Maximum Power Output of cell is defined as the bias potential at which the solar cell outputs the maximum net power. It represents the optimal operating point where the solar cell delivers the highest possible power output.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P_m = \frac{\frac{[Charge-e] \cdot V_m^2}{[BoltZ] \cdot T}}{1 + \frac{[Charge-e] \cdot V_m}{[BoltZ] \cdot T}} \cdot (I_{sc} + I_o) \]

Where:

\( P_m \) — Maximum Power Output of cell (Watt)
\( V_m \) — Voltage at Maximum Power (Volt)
\( T \) — Temperature in Kelvin (Kelvin)
\( I_{sc} \) — Short Circuit Current in Solar cell (Ampere)
\( I_o \) — Reverse Saturation Current (Ampere)
\( [Charge-e] \) — Charge of electron (1.60217662 × 10⁻¹⁹ C)
\( [BoltZ] \) — Boltzmann constant (1.38064852 × 10⁻²³ J/K)

Explanation: The formula calculates the maximum power output by considering the voltage at maximum power, temperature, short circuit current, and reverse saturation current, using fundamental physical constants.
