Is there a correlation between voltage and power output in PV cells? If so, how does increasing voltage affect power output?

Yes, there is a correlation between voltage and power output in photovoltaic (PV) cells. The relationship between voltage, current, and power output can be understood through the basic electrical formula: P=V ⋅ I where: P is the power, V is the voltage, I is the current. In the context of PV cells,
