Electrical characterization with high spatial resolution of P3HT:PCBM blends used in organic photovoltaics by means of conductive atomic force microscopy

Omar Y.M., Chiesa M., Apostoleris H.N., Al Ghaferi A., Masdar Institute, AE

Conductive atomic force microscopy was used to characterize P3HT-PCBM blends in the nanoscale with high spatial resolution. Local spectroscopy scans were obtained and charge carrier mobility was determined.

National Science Foundation’s Organic and Flexible Electronics Programs in the Engineering Directorate

Kaul A.B., National Science Foundation, US

Organic semiconductors display fascinating properties which has enabled their application in low-cost, high-efficiency organic photovoltaics (OPV), as well as in flexible and printed electronics for OLEDs for solid state lighting and displays. In particular, the [...]

Nano-enabled Green Technologies for Electronics and Energy Applications

Kaul A.B., National Science Foundation, US

Green electronics is largely driven by performance limitations of scaled Si-based CMOS due to the exceptionally high power dissipation arising in such devices at nanoscale dimensions. Novel architectures for computation are currently in consideration, which [...]
