6 FAQs about [Short-circuit current of single crystal cell]
What is the short-circuit current density of a flat reference solar cell?
The short-circuit current density of the flat reference solar cell is 13.8 mA/cm 2, which is increased to 21.4 mA/cm 2 using a period of 200 nm and a height of 1500 nm. The enhancement of the short circuit current density is mainly obtained due to the enhanced optical thickness of the solar cell.
What happens when a cell is switched from open circuit to short circuit?
This effect had been described previously. When the cell is switched from open circuit back to short circuit, the measured JSC and the charge extraction is first high and then decreases toward a steady-state value within 20 s.
Do perovskite solar cells have a short-circuit current loss?
