Implication

Experimental study demonstrates over 13% efficiency in fullerene-free tandem organic solar cells, indicating the potential of tailored non-fullerene acceptors for advanced photovoltaics.

Key Points

To improve the power conversion efficiency of tandem organic solar cells by engineering complementary non-fullerene photoactive layers and an efficient interconnection layer.
Designed a non-fullerene acceptor with an optical band gap of 1.68 eV for front subcells and optimized phase-separation morphology in a 1.36 eV band gap rear subcell.
Developed an interconnection layer using zinc oxide combined with a pH-neutral, self-doped conductive polymer (PCP-Na) providing high near-infrared transmittance.
The front and rear subcells demonstrated complementary absorption spectra, high external quantum efficiency, and low energy losses.
The fully solution-processed fullerene-free tandem organic solar cells achieved an average power conversion efficiency exceeding 13%.
