A tandem solid-state dye-sensitized solar cell (SSDSC) without color distortion for potential photovoltaic window applications is reported. The bifacial tandem SSDSC with two spectrally complementary sensitizers using parallel-connection is realized, which leads to non-color distortion. The Commission Internationale de l'Eclairage (CIE) chromaticity diagram is applied to verify the extent of color distortion. At this circumstance, the photovoltaic performance for the tandem SSDSC with a power conversion efficiency of 3.3% was achieved under AM 1.5G, 100 mW/cm(2) illumination. The overall efficiency in the tandem architecture outperformed each individual cell. Our results demonstrate the feasibility for visible light transmission, non-color distortion, power-generating windows for application in building-integrated photovoltaics (BIPV). Moreover, this tandem SSDSC architecture has potential for the integration into window curtains application due to its flexible characteristics. With further extension of the absorber spectrum into the IR region, a better solid-state tandem DSC is expected. (C) 2013 Elsevier Ltd. All rights reserved.
