Book - Chapter 9

Question 1

Short Circuit Density (Isc)

Answer 1

• Depends on the area of the solar cell
• Often used to describe the maximum current delivered by a solar cell
• The maximum current that a solar cell can deliver depends on absorption in the layer and reflection

Question 2

Open Circuit Voltage (Voc)

Answer 2

• Voltage at which no current flows through the external circuit
• Maximum voltage a solar cell can deliver
• Corresponds to the bias voltage
• Depends on the saturation current density of a solar cell and the photo generated current

Question 3

Fill Factor

Answer 3

Ratio between the maximum power generated by a solar cell and the product of Voc with Isc

Question 4

MPP

Answer 4

Maximum Power Point

Question 5

MPPT

Answer 5

Maximum Power Point Tracking

Question 6

Main parameters that are used to characterize the performance of solar cell

Answer 6

• Peak Power (Pmax)
• Short Circuit Current (Isc)
• Open Voltage (Voc)
• Fill Factor (FF)
