Since the inception of heterojunction organic photovoltaic research the organic/organic interface has been thought to play a crucial role in determining the magnitude of the open-circuit voltage. Yet, the task of defining the molecular properties dictating the photovoltage delivered by these devices, that employ mixed or neat layers of different organic molecules to convert incident photons to electricity, is still an active area of research. This will likely be a key step in designing the new materials required for improving future device efficiencies. With the intent to underscore the importance of considering both thermodynamic and kinetic factors, this article highlights recent progress in elucidating molecular characteristics dictating photovoltage losses in heterojunction organic photovoltaics.
自异质结有机光伏研究问世以来，人们一直认为有机/有机界面在决定开路电压的大小方面起着至关重要的作用。然而，确定这些器件的电压的分子特性的任务，这些器件采用不同有机分子的混合或纯层来将入射光子转换为电能，仍然是一个活跃的研究领域。这可能是设计提高未来器件效率所需新材料的关键步骤。本文旨在强调考虑热力学和动力学因素的重要性，重点介绍了阐明决定异质结有机光伏中电压损失的分子特性的最新进展。
