The short circuit current of a solar cell is

• A. directly proportional to radiation intensity
• B. constant and not affected by radiation
• C. changes logarithmically with radiation
• D. inversely proportional to radiation intensity

Answer: (A)

Short circuit current is the current passing through a solar cell when voltage is zero across the solar cell, which happens when a solar cell is short circuited.
Usually it is denoted Isc.
solar cell have short-circuit currents between about 28 mA/cm² and 35 mA/cm²
