摘要
In tandem: Employing a molecular dyad and a cobalt-based electrolyte gives a threefoldincrease in open-circuit voltage (VOC) for a p-type NiO device (VOC=0.35 V), and a fourfold better energy conversion efficiency. Incorporating these improvements in a TiO2/NiO tandem dyesensitized solar cell (TDSC), results in a TDSC with a VOC=0.91 V (see figure; CB=conductance band, VB= valence band). © 2009 Wiley-VCH Verlag GmbH & Co.
