Basic properties of solar cells

Photoelectric conversion efficiency

η% An important factor in evaluating the quality of a solar cell.

At present: laboratory η ≈ 24%, industrialization: η ≈ 15%.

Single cell voltage

V: 0.4V - 0.6V is determined by the physical properties of the material.

Fill factor FF%

An important factor in assessing the load capacity of solar cells. FF=(Im×Vm)/(Isc×Voc)

Where: Isc - short circuit current, Voc - open circuit voltage, Im - optimal operating current, Vm - optimal operating voltage;

Standard light intensity

AM1.5 light intensity, 1000W/m2, t = 25°C;

Effect of temperature on battery properties

For example, under standard conditions, the AM1.5 light intensity, t=25°C, the output power of a panel is measured to be 100Wp. If the battery temperature rises to 45°C, the output power of the panel is less than 100Wp.
