Charge Transport Simulation in Single-Layer Oil-Paper Insulation

AbstractOrganic electroluminescent(EL) diodes using spin-coat films of cyclohexane-based glass-forming liquid crystal (LC) materials were fabricated. The cyclohexane-based LC materials were found to be useful for EL diodes. Blending the LC materials with charge transport molecules was found to be a promising method for improving device performance. Conventional hole transport and electron transport molecules were found to show a tendency to form exciplexes with cyclohexanebased LC materials. This difficulty was overcome by the introduction of cyclohexane-based charge transport molecules. The EL quantum efficiency of 0.06% was attained in the single-layer devices with two-component blends.

Charged Impurity Scattering

Abstract Both intrinsic and extrinsic charge transport properties of methylammonium lead triiodide perovskites are investigated from first-principles. The weak electron-phonon couplings are revealed, with the largest deformation potential (~ 5 eV) comparable to that of single layer graphene. The intrinsic mobility limited by the acoustic phonon scattering is as high as a few thousands cm2 V−1 s−1 with the hole mobility larger than the electron mobility. At the impurity density of 1018 cm−3, the charged impurity scattering starts to dominate and lowers the electron mobility to 101 cm2 V−1 s−1 and the hole mobility to 72.2 cm2 V−1 s−1. The high intrinsic mobility warrants the long and balanced diffusion length of charge carriers. With the control of impurities or defects as well as charge traps in these perovskites, enhanced efficiencies of solar cells with simplified device structures are promised.
