Suppressing Non-radiative Energy Loss of Organic Solar Cells by Embedding Nitroxide Radical Blocks in Wide Bandgap Conjugated Polymer Donors

The large non-radiative recombination losses (〖ΔV〗_oc^(non-rad)) of non-fullerene acceptors-based organic solar cells (NFAs-OSCs) are recognized as the main limitation to further boosting their efficiency to a new regime. In this...
