P‐120: Degradation Mechanism and Lifetime Improvement of Blue Quantum‐Dot Light‐Emitting Diodes

SID Symposium Digest of Technical Papers (2019)

Wen‐Cheng Ding Chun-Yu Lee Chia‐Hsun Chen Li-Jen Huang Ya-Pei Kuo

We have demonstrated that degradation of the hole‐transporting layer material in the blue quantum‐dot light‐emitting diode (QLED) is the main reason accounts for the efficiency loss operated under constant current driving, and the operation lifetime can be elongated by 85% under pulse‐mode driving compared to DC case.

Modeling of carrier transport in organic light emitting diode with random dopant effects by two-dimensional simulation

Optics Express (2017)

Te-Jen Kung Jun‐Yu Huang Jau‐Jiun Huang Snow H. Tseng Man‐kit Leung

To model the carrier transport in organic light-emitting diodes (OLEDs) with random dopant effects in the emitting layer, two-dimensional simulation was used. By including the Gaussian shape density of states and field-dependent mobility in the Poisson and drift-diffusion solver, the carrier transport, trapping in the dopant state, and radiative recombination were accurately modeled. To examine the model, the current-voltage characteristics of organic light-emitting devices were compared. The host material in the emitting layer was 2,2-bis(1-phenyl-1H-benzo[d]imidazol-2-yl)biphenyl (BImBP), which was doped with bis[2-(4,6-difluorophenyl)pyridinato-C2,N](picolinato)iridium(III) (FIrpic) at various concentrations. By including the random doping model, the trend of mobility was altered and the radiative efficiency fitted experimental values well.

Hoang Yan Lin Sheng-Chih Hsu Jiun‐Haw Lee Mao‐Kuo Wei

A microlens array formed by thermal reflow is attached to an OLED (organic light emitting diode) device and the light extraction efficiency can be enhanced. The efficiency improvement is simulated by a ray-tracing algorithm and is greatly influenced by adjusting the area ratio and the height ratio

P‐158: Connecting Architecture for Organic Light‐emitting Diodes Integrated with Organic Photovoltaic Device

SID Symposium Digest of Technical Papers (2010)

Shun‐Wei Liu Chih‐Chien Lee Jia‐Chin Huang Chi‐Feng Lin Chin‐Ti Chen

Abstract Silver electrode with self‐assembled monolayers (SAMs) modification was used as the connecting unit for the anode of a top‐emitting OLED and the cathode of an organic photovoltaic (OPV) device. This tandem device exhibits the power conversation efficiency of ∼0.9% under 1‐sun illumination (OPV‐mode) and thecurrent efficiency of ∼10 cd/A at 10000 cd/m 2 (OLED‐mode).

Easy Access to NO₂‐Containing Donor–Acceptor–Acceptor Electron Donors for High Efficiency Small‐Molecule Organic Solar Cells

ChemSusChem (2016)

Hao‐Chun Ting Ya-Ting Carolyn Yang Chia‐Hsun Chen Jiun‐Haw Lee Jung‐Hung Chang

Abstract Two donor–acceptor–acceptor (D–A–A)‐type molecules incorporating nitrobenzoxadiazole (NBO) as the A–A block and ditolylamine as the D block bridged through a phenylene (PNBO) and a thiophene (TNBO) spacer were synthesized in a one‐step coupling reaction. Their electronic, photophysical, and thermal properties; crystallographic analysis; and theoretical calculations were studied to establish a clear structure–property relationship. The results indicate that the quinoidal character of the thiophene bridge strongly governs the structural features and crystal packings (herringbone vs. brickwork) and thus the physical properties of the compounds. PNBO and TNBO were utilized as electron donors combined with C 70 as the electron acceptor in the active layer of vacuum‐processed bulk heterojunction small‐molecule organic solar cells (SMOSCs). The power conversion efficiency of both PNBO‐ and TNBO‐based OSCs exceeded 5 %. The ease of accessibility of PNBO and TNBO demonstrates the potential for simple and economical synthesis of electron donors in vacuum‐processed SMOSCs.
