The authors of this CRC 951 research highlight elucidate the origin of limited upward band bending by revealing a notable gap state density-of-states (GDOS)
using high-sensitivity photoemission spectroscopy. Upon acceptor-induced upward band bending, the GDOS with a wide energy distribution becomes increasingly unoccupied.

The authors of this CRC 951 research highlight demonstrate that the surface photovoltage (SPV) is a key phenomenon occurring at the perovskite surfaces that feature a non-negligible density of surface states, which is more the rule than an exception for most materials understudy.

The authors of this CRC 951 research highlight combine the results of EL and photovoltaic measurements to eliminate the unavoidable effect of the series resistance of inorganic and organic components on the total voltage drop across the hybrid device.
