Here's why:
* Voltage is determined by the material: The voltage a solar cell produces is primarily determined by the material it's made of (e.g., silicon). The band gap of the semiconductor material dictates the energy level of photons that can be absorbed and converted into electrons, thus determining the voltage.
* Current is dependent on area: The current a solar cell produces is directly proportional to the area exposed to light. More surface area means more photons can be absorbed, leading to a higher current.
* Power is the product of voltage and current: The power output of a solar cell is the product of its voltage and current. Therefore, increasing the area of a solar cell increases its current, which in turn increases its power output.
In summary: While the area of a solar cell influences its current and power output, it does not affect the voltage it produces. The voltage is primarily determined by the type of semiconductor material used.
