Photovoltaic Cells
With an incident irradiance of 1 kW m −2 (spectrum AM 1.5), the current density J PV reaches values of 10–40 mA cm −2 depending on the material used and the construction of the cell. The current I PV is directly proportional to the area of the cell such that, for example, a standard silicon cell 15. 6 × 15.6 cm 2 can generate a current of about 8 A.

Internal resistance
This is completely different in solar cells: In this case, the internal resistance is relatively high and depends greatly on the illuminance. In a 0.6V/150mV silicon solar cell, the internal resistance is up to 4 ohms in bright lighting. This is why the voltage drops significantly when a low-resistance load is connected.
