Copper bipyridyl redox couples are intresting mediators for dye-sensitized solar cells (DSSCs). Here we show that the electrolyte additive 4-tert-butylpyridine (TBP) actually substitutes common bidentate ligands on the Cu(II) species to form [Cu(TBP)₄]²⁺, which is a poor electron acceptor and thus allows high voltages and charge collection efficiencies to be achieved.

染料敏化太阳能电池中铜联吡啶氧化还原对的原位配体交换反应诱导的性能改善†

联吡啶氧化铜对是染料敏化太阳能电池（DSSC）的重要介体。在这里，我们显示电解质添加剂4-叔丁基吡啶（TBP）实际上替代了Cu（II）物种上的常见双齿配体以形成[Cu（TBP）₄ ] ²⁺，这是一种弱电子受体，因此允许高压以及要达到的收费效率。
