Organic photovoltaic devices (OPVs) are realizing power conversion efficiencies that are of interest for commercial production. However, cell efficiencies are poor to modest when compared to their more traditional silicon and other inorganic based counterparts. Apart from material breakthroughs, there is immense need to therefore engineer novel approaches to improve OPV cell performance. In this work,...
The low-frequency noise of bottom-gate amorphous IGZO thin-film transistors is investigated in the low drain current range. The noise spectra show generation–recombination (g-r) noise at drain currents , attributed to bulk traps located in a thin layer of the IGZO close to the conducting channel. At higher drain currents, a pure noise is observed. It is shown...
This paper discusses oxide-semiconductor (amorphous Indium Gallium Zinc Oxide, IGZO in particular) based thin-film transistors (TFTs) which provide san attractive alternative to silicon-based TFTs. This study systematically investigates the influence of tensile strain on IGZO TFTs and ring oscillators fabricated on flexible stainless steel substrates.
