  1. J sc, V oc, FF, and η denote saturated photocurrent, open circuit voltage, fill factor, and overall efficiency, respectively
  2. A as a function of ambient oxygen pressure for ZnO deposition (the thicknesses of all the ZnO films were fixed to be 10 μm)
  3. B as function of film thickness (all films were deposited under 300 mTorr)
