TCO work function tuning by nanodiamonds
Čermák, Jan ; Miliaieva, Daria ; Sokeng-Djoumessi, A. ; Hoppe, H. ; Stehlík, Štěpán
Deposition of nanodiamonds is found to be able to adjust the work function of transparent conductive oxides that are commonly used in photovoltaics. It also turned out that the change is dependent on the nanodiamond surface termination and that it is not stable in time.
Back electrode influence on opto-electronic properties of organic photovoltaic blend characterized by Kelvin probe force microscopy
Čermák, Jan ; Miliaieva, Daria ; Hoppe, H. ; Rezek, Bohuslav
Organic photovoltaic (PV) system consisting of P3HT:PCBM blend layer was prepared with an aluminum (Al) back electrode. After the final thermal annealing the Al layer was partially removed. Kelvin Probe Force Microscopy (KPFM) was used to measure photovoltage response to illumination by a solar spectrum light as a function of time (up to 3 weeks). Comparison of the same KPFM measurement on the areas with and without Al revealed differences in both morphology and photovoltage response to illumination. The data are discussed with view to reducing degradation of organic PV devices.\n
