Introduction Why is the current of the solar cell (2W) I bought measured with a multimeter under relatively strong sunshine only 0.1A (normally it should be 4A). The voltage of a single solar cell is 0

Why is the current of the solar cell (2W) I bought measured with a multimeter under relatively stron

The voltage of a single solar cell is about 0.5 volts, so if the power is 2 watts, the current should actually be 4 amps. What setting of the multimeter did you use to measure the current? The multimeter has internal resistance when measuring current, and measuring a power supply with such a low voltage will have a great impact. You can try using level 10A to test it.
