Final answer:

To calculate the solar cell efficiency and fill factor, specific formulas involving the maximum power output, incident light power, and solar cell area are used. However, with the provided data, the calculation cannot be completed as the open-circuit voltage (Voc) is not given and cannot be derived with the current information.

Step-by-step explanation:

To calculate the solar cell efficiency and fill factor for a silicon solar cell, we first need to understand the basic parameters involved.

The efficiency (η) of a solar cell is given by the ratio of the maximum power output (Pmax) to the product of the incident light power (Pin) and the area (A) of the solar cell:

η = (Pmax / (Pin × A)) × 100%

The fill factor (FF) is a measure of the solar cell's quality and is defined as the ratio of the actual maximum obtainable power (Pmax) to the product of the open-circuit voltage (Voc) and the short-circuit current (Isc):

FF = Pmax / (Voc × Isc)

In order to find the efficiency and fill factor, we also need to know the open-circuit voltage, which depends on the saturation current and the short-circuit photocurrent. However, with the information provided, we can't calculate Voc directly without assuming additional constants like temperature and ideality factor or applying the Shockley Equation. As this information is not provided, we can not proceed with the actual calculation.

If all the necessary data were available, we could then calculate the Pmax, and plug into the above formulas to finally calculate the efficiency and fill factor of the solar cell.
