Influence of oxygen doping on the electrical and photovoltaic properties of Schottky type solar cells based on α-nickel phthalocyanine

Long time stability of ITO/NiPc/ZnO/Al devices with ZnO buffer layer formed by atomic layer deposition technique–impedance spectroscopy analysis

“…This diagram is based on the values adopted from Refs. [13][14][15][16]. The presence in band diagram of the exponential distribution of trapping levels above the valence band edge is caused by the oxygen molecules [12] and it is in good agreement with analysis of experimental I-V characteristics.…”

High‐Performance Air‐Processed Polymer–Fullerene Bulk Heterojunction Solar Cells

“…[21,25] Oxygen exposure has reportedly increased the PV performance of devices having active layers composed of other types of organic semiconductors. [27,28] In this report, we rationalize the effects of oxygen exposure on P3HT:PCBM BHJ solar cells fabricated in ambient-air environments by correlating changes in the devices' physical and chemical structures with the corresponding PV performance and electronic transport properties. Detailed analysis of the reverse and forward bias current-voltage (J-V) characteristics from model device structures allows examination of the influence of oxygen on electron and hole mobilities, carrier concentrations, and charge trap densities, which we associate with the PV conversion performance of similarly processed solar cell devices.…”

Study of Barrier Structures on the Base of Nickel Phthalocyanine Thin Films During the Interaction with the Ammonia Medium

“…This material exhibits the p-type conductivity in air due to the absorption of atmospheric gases [7]. Moreover, it is sensitive to other gases [8][9][10] and solar radiation [11,12]. Finally, NiPc has a high thermal and chemical stability and can be used as a catalyst [13].…”

“…Finally, NiPc has a high thermal and chemical stability and can be used as a catalyst [13]. It was shown that this material can be used in gas sensors, solar cells, and other electronic devices [7][8][9][10][11][12][13]. For example, NiPc is used in systems of chemical identification; these systems being based on the effect of conductivity change due to the selective absorption of O 2 , NO, NO 2 , and HCl [8,10,14,15].…”
