Does a solar cell always maintain the potential across its terminals constant? Discuss

उत्तर
A solar cell does not always maintain a constant potential difference across its terminals.
Its voltage depends on the intensity of sunlight, temperature, and the load connected to it. In strong light and with a light load, the terminal voltage is high. When the light intensity decreases or when a heavy load is connected, the voltage drops. Thus, unlike a battery, a solar cell cannot maintain a constant potential difference under all conditions.

The values of current (I) flowing through a given resistor of resistance (R), for the corresponding values of potential difference (V) across the resistor are as given below:
| V (volts) | 0.5 | 1.0 | 1.5 | 2.0 | 2.5 | 3.0 | 4.0 | 5.0 |
