ENLIGHTEN - Enabling Organic Electronics by Design

目前用于有机电子器件（如LED和光电器件）的建模软件通常使用从传统半导体借用的模型，仅通过考虑电荷载流子迁移率具有场依赖性来修改。最近人们认识到，有机半导体中无序的存在意味着迁移率对载流子密度的依赖性与场依赖性一样重要。因此，目前的模型无法基于一组参数在不同条件下提供对器械性能的一致描述，并且从模型中提取的微观参数往往具有误导性。在这个项目中，我们的目标是开发改进的模型，考虑到无序，不仅为载流子输运，而且为电荷分离和注入。我们将根据实验数据，特别是温度相关数据验证这些模型，并将协助将成功的模型转移到其他合作伙伴开发和使用的易于使用的软件包中。

Current modelling software for organic electronic devices such as LEDs and photovoltaics typically uses models borrowed from conventional semiconductors, modified only by considering that the charge carrier mobility has a field dependence. Recently it has been appreciated that the presence of disorder in organic semiconductors means that the dependence of mobility on carrier density is just as important as the field dependence. Current models are therefore unable to provide a consistent description of device performance under different conditions based on a single set of parameters, and the microscopic parameters extracted from models are often misleading. In this project we aim to develop improved models that take into account disorder, not just for carrier transport but also for charge separation and injection. We will validate these models against experimental data, particularly temperature-dependent data, and will assist in transferring successful models into the easy-to-use software packages developed and used by other partners.
