Joule: Which One Is The Most Cited Article?

SS-X solar simulator makes the breakthrough possible!

  The emergence of Y6 has greatly improved the conversion efficiency of OPV from 12% to nearly 16%. By 2021, the conversion efficiency of OPV has approached 19%. Joule (IF 41.248) published the article Single-Junction Organic Solar Cell with over 15% Efficiency Using Fused-Ring Acceptor with Electron-Deficient Core in April 2019. This article has been cited for over 2,100 times within 3 years, which shows its importance in the OPV field.

Joule Single-Junction Organic Solar Cell with over 15% Efficiency Using Fused-Ring Acceptor with Electron-Deficient Core

  Non-fullerene acceptor (NFA) organic photovoltaics (OPV) have great potential to achieve high power conversion efficiency (PCE). But achieving high-efficiency charge separation/transport and low voltage loss at the same time is a big challenge. In this study, scientists optimized the molecular structure and synthesized a new non-fullerene receptor Y6, which matched the commercially available polymer PM6. Through solar simulator and reference cells from Enlitech, scientists measured that Y6 solar cells can provide 15.7% high power conversion efficiency (PCE) in both conventional and inverted architectures.

  In order to confirm the high PCE reliability of the PM6:Y6 device, the scientists sent the optimized inverted device to Enlitech ISO Photovoltaic Efficiency Verification Laboratory (certified by ISO/IEC 17025) and verified that the PCE was 14.9% (Voc: 0.83 V,Jsc: 23.2 mA cm-2,FF: 76.8%). The scientists further observed that the Y6 device still maintained a high efficiency of 13.6% at a thickness of 300 nm, showing that Y6 is an excellent acceptor for high-efficiency OPV.
