Abstract

The voltage loss, determined by the difference between the optical gap (Eg) and the open‐circuit voltage (VOC), is one of the most important parameters determining the performance of organic solar cells (OSCs). However, the variety of different methods used to determine Eg makes it hard to fairly compare voltages losses among different material systems. In this paper, the authors discuss and compare various Eg determination methods and show how they affect the detailed calculation of voltage losses, as well as predictions of the maximum achievable power conversion efficiency. The aim of this paper is to make it possible for the OSC community to compare voltage losses in a consistent and reasonable way. It is found that the voltage losses for strongly absorbed photons in state‐of‐the‐art OSCs are not much less than 0.6 V, which still must be decreased to further enhance efficiency.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
