1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Narrow-bandgap acceptors are the basis for achieving high short-circuit current density in organic solar cells; however, the lack of effective strategies to reduce energy loss under narrow-bandgap systems makes it challenging to solve the trade-off of open-circuit voltage and short-circuit current density. Here an acceptor Qx-Se-NF, featuring quinoxaline (Qx) central moiety, naphthyl-based terminal group (NF), and selenium (Se)-substituted central core, is synthesized, reaching a narrow bandgap of 1.31 eV. Theoretical calculations show that Qx-Se-NF exhibits low energetic disorder, which is beneficial for reducing energy loss. Furthermore, its strong aggregation properties tend to form a unique vertically segregated alloy structure in ternary systems, which is beneficial for increasing the short-circuit current density without sacrificing the open-circuit voltage. As a result, the ternary system achieved a certified power conversion efficiency of 21.01% with a low energy loss of 0.486 eV, providing a deep insight into the design of narrow-bandgap acceptors and their ternary systems.
