Abstract

Read online

Improving the power conversion efficiency is the main target of the organic solar cell research. Here Yuan et al. develop unconventional electron-deficient-core-based non-fullerene acceptors to achieve both low voltage loss and high current density, leading to a certified high efficiency of 12.6%.
