Solar Cell Maximum Power Calculation

This solution demonstrates calculating the maximum power output of a silicon solar cell given its short-circuit current ($I_{sc}$), open-circuit voltage ($V_{oc}$), and fill factor (FF).

Key Formula

The maximum power ($P_{max}$) delivered by a solar cell is determined by the following formula:

$ P_{max} = V_{oc} \times I_{sc} \times FF $

Input Values

The provided values are:

• Short-circuit current, $I_{sc} = 100 \text{ mA} = 0.1 \text{ A}$
• Open-circuit voltage, $V_{oc} = 0.8 \text{ V}$
• Fill Factor, $FF = 0.7$

Calculation Steps

1. Substitute the known values into the formula:

   $ P_{max} = (0.8 \text{ V}) \times (0.1 \text{ A}) \times 0.7 $

2. Calculate the product:

   $ P_{max} = 0.056 \text{ W} $

3. Convert the power from Watts (W) to milliwatts (mW):

   $ P_{max} = 0.056 \text{ W} \times 1000 \frac{\text{mW}}{\text{W}} = 56 \text{ mW} $

Therefore, the maximum power delivered by the solar cell is 56 mW.
