Solar cells are usually accompanied by parasitic series resistance and parallel (shunt) resistance, as shown in Figure 3. Both parasitic resistances will cause FF to decrease. If there are series resistance R s and parallel resistance R sh at the same time, the volt-ampere characteristic curve of the solar cell is given by the following formula:
The FF of a solar cell is often the most difficult parameter to optimize because it is sensitive to a range of parasitic loss mechanisms, such as resistance losses, which generally have only a minor impact on V OC or I SC. The upper limit on the FF is determined by the V OC of the solar cell [Eq. 4: 18
If the resistance of the load is equal to the characteristic resistance of the solar cell, then the maximum power is transferred to the load, and the solar cell operates at its maximum power point. It is a useful parameter in solar cell …
