a ETL dependent EQE spectra in an inverted 500 nm thick PCE10:COTIC-4F photodiode. For the ETL-free (gray dash line) inverted device, the ITO substrate was not treated by UV Ozone since it would increase the energy barrier for electron extraction. b Corresponding J–V characteristics measured under a 808 nm LED source at ~6 mw/cm2. c Mott–Schottky plots of ETL dependent PCE10:COTIC-4F devices, measured at 1 kHz in the dark.
