As an example, a band gap difference of 0.04 eV was found for CH3NH3PbI3 when using this procedure (DFT-1/2 band gaps of 1.84 eV vs 1.88 eV).
The 10 nm Zn(O,S /TONR array exhibits a significantly enhanced photocurrent density (Jsc) of 5.94 matcm2 at 1.23 eV vs NHE and an incident photon-to-electron conversion efficiency (IPCE) of 49% at 374 nm compared with that of TONR arrays (Jsc of 1.99 matcm2 at 1.23 eV vs NHE and an IPCE of 20% at 380 nm).
However, the PEC performance is worse in the 30 nm Zn(O,S /TONR arrays, showing a Jsc of 3.09 matcm2 at 1.23 eV vs NHE and an IPCE of 29% at 374 nm.
The highest-occupied molecular orbital (HOMO) and lowest-unoccupied molecular orbital (LUMO) energy levels of these PIs were determined in the range of −4.95 to −5.00 and −1.97 to −2.01 eV (vs the vacuum level) by cyclic voltammetry method which were consisting with the results of quantum chemical calculation well, respectively.
The conduction band of TiO2 is −4.2 eV (vs. vacuum) [33].

In fractionated spheroids, the outermost cells exhibited similar responses to oxaliplatin (SF 10 μ M oxaliplatin 0.061 EV vs 0.066 for DN), consistent with monolayers.
