The molecular nature of photovoltage losses in organic solar cells

Author affiliations

Abstract

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.
