项目摘要
Organic solar cells meanwhile reach power conversion efficiencies of more than 11%, however, in comparison to inorganic cells they lose disproportionately in energy. This means the so-called bandgap-voltage offset between the onset energy for light absorption and the open-circuit voltage of the solar cell is in most cases much bigger than the value of about 0.4 eV obtained for Si and GaAs. The goal of this project is to gain a deeper understanding of the origin of energy losses in organic solar cells and to develop strategies to reduce them. To achieve this goal we will use structurally well-defined donor-acceptor heterojunctions based on molecular materials as model systems and systematically investigate the influence of parameters like structural order, molecular orientation or intermixing of the two partners at their mutual interface. Applying temperature dependent electrical transport measurements and optical spectroscopy, we plan to elucidate the detailed role of the interfacial charge transfer state for power generation in organic solar cells.
有机太阳能电池同时达到超过11%的功率转换效率,然而,与无机电池相比,它们损失的能量不成比例。这意味着,在大多数情况下,光吸收的起始能量与太阳能电池的开路电压之间的所谓带隙电压偏移远大于Si和GaAs获得的约0.4eV的值。该项目的目标是更深入地了解有机太阳能电池中能量损失的根源,并制定减少能量损失的战略。为了实现这一目标,我们将使用基于分子材料的结构明确的供体-受体异质结作为模型系统,并系统地研究结构顺序,分子取向或两个合作伙伴在其相互界面处的混合等参数的影响。应用温度相关的电输运测量和光学光谱,我们计划阐明在有机太阳能电池的发电界面电荷转移状态的详细作用。
