The main impact of series resistance is to ______ the fill factor. Increase Decrease Double Multiply

Break Down the Problem

1. Identify the term related to series resistance in the context of the fill factor of a solar cell.
2. Understand the relationship between series resistance and the fill factor.

Relevant Concepts

1. Fill Factor (FF): It indicates the quality of a solar cell and is defined as the ratio of the maximum power from a solar cell to the product of its open-circuit voltage and short-circuit current.
2. Series Resistance: This is the resistance faced by the current as it flows through the solar cell. Increased series resistance can lead to a decrease in current output.

Analysis and Detail

1. When series resistance increases, it tends to lower the current output for a given voltage, which can negatively affect the maximum power point.
2. A lower maximum power point generally translates into a lower fill factor since FF is dependent on both current and voltage outputs of the solar cell.

Verify and Summarize

1. The increased series resistance leads to losses in power conversion efficiency.
2. Therefore, the fill factor is adversely affected by an increase in series resistance, leading to lower overall performance of the solar cell.

Final Answer

The main impact of series resistance is to decrease the fill factor.
