A paper “19.31% binary organic solar cell and low non-radiative recombination enabled by non-monotonic intermediate state transition” published by Prof. Gang Li’s research team on Nature Communications on 30 March 2023 was selected as the Editors’ Highlights under the topic of devices. Non-radiative recombination loss suppression is critical for boosting performance of organic solar cells. Here, the authors regulate self-organization of bulk-heterojunction in a non-monotonic manner, and achieve device efficiency over 19% with low non-radiative recombination loss down to 0.168 eV.
