Revealing defective interfaces in perovskite solar cells from highly sensitive sub-bandgap photocurrent spectroscopy using optical cavities
Sensitive photocurrent spectroscopy and interference of light in perovskite solar cells with optical spacers reveal that electronic defects in these devices are localized at the interface between the semiconductor and the electron collecting contact.
