  1. The errors are defined as the standard deviation
  2. aAperture with an area of 0.04 cm2 was used
  3. bAperture with an area of 0.9062 cm2 was used
  4. cThe volume ratio of DBE is 0.1%
  5. dJSC, EQE is defined as the calculated current density from EQE spectra
  6. eThe average of current densities obtained from EQEs with light-spots concentrating on three locations of 1.0 cm2-cell
  7. fThe efficiency is calculated by, PCE = VOC·JSC, EQE·FF
