Softening temperature on sputtered ZnO interfacial barrier layer for an efficient charge transfer P3HT/ZnO and better interfacial stability in plastic organic photovoltaic devices

Temperature-dependent barrier height inhomogeneities in PTB7:PC71BM-based organic solar cells

“…[5] These interesting properties have made organic semiconductors very promising materials for research laboratories and manufacturers around the world, [6,7] provoking quick growth in the field of organic electronics. [8] For photovoltaic applications and for organic semiconductors, the charge transport mechanisms are controlled by bulk process, and the semiconductor/electrode interface can affect the charge transport. Thermoelectronic emission, Schottky effect and effect emission tunnel can be used to describe the mechanisms which are governed by the interface.…”
