Figure 4. Device structure, IPCE spectra and J–V characteristics of the hybridized cell.
(a) Device structure of the hybridized cell using a dichroic spectrum splitter. (b) Transmittance spectra of dichroic mirrors under measurement conditions such as incident of a 45° angle. (c) IPCE spectra of the individual components of the hybridized cell with various dichroic mirrors: visible absorbing cell, PSC (solid line); near-IR absorbing cell, DX3-based DSSC (dashed line). (d–g) Photovoltaic parameter and total power conversion efficiency dependence on the splitting wavelength of the dichroic mirrors: PSC (red), DX3-based DSSC (blue) and total power conversion efficiency of the hybridized cell (green).
