Prof. Gang Li’s research team published a paper “19.5% Inverted Organic Photovoltaic with Record Long-lifetime via Multifunctional Interface Engineering featuring Radical Scavenger” on Nature Communications on 04 December 2024, which reported breakthrough in both efficiency and lifetime of organic solar cells.
Advances in improving the operational lifetime of highly efficient organic photovoltaic (OPV) and understanding photo-degradation mechanisms in molecular level are currently limited, especially on the promising inverted OPV, posing critical challenges to commercialization. Here, the authors report a radical scavenger capped zinc oxide nanoparticles as the electron transport layer, achieving operationally stable devices with efficiency of 19.47%. Dr. Huang Jiaming is the first author. Dr. Jiehao Fu is equal contribution author.
