In this study, the space charge limited current transport model was applied to simulate the current density–voltage characteristics of two-layer NPB/Alq₃ organic light emitting diodes (OLEDs). Several parameters for simulations were moderately adjusted, and the best set of parameters were obtained. Upon increasing the applied voltage, the junction temperature of the OLED increased, further influencing the transport of the carriers. When the junction temperature was used as the reference temperature in analysis of the relationship between voltage and temperature, the simulated current density–voltage characteristics were found to be very consistent with the experimental data.

使用结温来调整温度对两层有机发光二极管电流-电压特性的影响的仿真

在这项研究中，使用空间电荷限制电流传输模型来模拟两层NPB / Alq ₃有机发光二极管（OLED）的电流密度-电压特性。对模拟的几个参数进行了适度的调整，并获得了最佳的参数集。随着施加电压的增加，OLED的结温升高，进一步影响载流子的传输。当以结点温度作为参考温度来分析电压和温度之间的关系时，发现模拟的电流密度-电压特性与实验数据非常吻合。
