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

The realization of high-performance organic photovoltaics via environmentally benign manufacturing is pivotal for sustainable energy. While all-polymer solar cells (all-PSCs) offer superior stability and mechanical resilience, achieving high efficiencies in nonhalogenated green solvents remains a formidable challenge. Here, we report a "steric-locking" strategy for polymer acceptor design that enables a record-breaking power conversion efficiency of 20.53% (certified 19.79%) in o-xylene-processed all-PSCs. The introduction of a steric-locking guest polymer acceptor (PY-IDT) into the PM6:PYF-T-o host matrix profoundly regulates the crystallization kinetics and suppresses the excessive self-aggregation of the host acceptor. This molecular-level structural refinement significantly reduces energetic disorder and minimizes non-radiative voltage loss. Consequently, the suppressed energetic disorder and refined nanostructured domains yielded a concurrent leap in open-circuit voltage (0.942 V) and fill factor (82.11%). Furthermore, the steric-locked morphology demonstrates exceptional mechanical robustness, maintaining 92.6% of its initial efficiency after 1000 bending cycles. This work establishes a new efficiency benchmark and provides a universal chemical framework for developing high-performance, sustainable, and flexible optoelectronics.
