Analytical model for interface recombination limited ideality factors in p-i-n perovskite solar cells

APL Energy
Perovskite solar cells have emerged as a promising thin-film solar cell technology. However, compared to state-of-the-art photovoltaic technologies, perovskite solar cells still suffer from large nonradiative recombination losses. A dominant nonradiative

A review of high ideality factor in gallium nitride-based light-emitting diode

, 2021
Theory concerning the high ideality factor of gallium nitride (GaN) based light emitting diode (LED) has been reviewed. The presence of a high ideality factor indicates a large forward voltage that results in efficiency reduction. The paper suggests that

Origin of the dark-current ideality factor in polymer:fullerene bulk heterojunction solar cells [PDF]

, 2011
In organic bulk heterojunction solar cells, a deviation of the ideality factor of the dark current from unity is commonly put forward as evidence for the presence of trap-assisted recombination.

Thermal ideality factor of hydrogenated amorphous silicon p-i-n solar cells [PDF]

, 2011
The performance of hydrogenated amorphous silicon (a-Si:H) p-i-n solar cells is limited, as they contain a relatively high concentration of defects. The dark current voltage (JV) characteristics at low forward voltages of these devices are dominated by ...

Identifying dominant recombination mechanisms in perovskite solar cells by measuring the transient ideality factor [PDF]

, 2019
The light ideality factor determined by measuring the open circuit voltage (VOC) as function of light intensity is often used to identify the dominant recombination mechanism in solar cells.
