Novel photoelectrochromic cells fabricated with wirelike photo-electrode

A novel structure of photoelectrochromic cell fabricated with titanium wirelike photo-electrode is introduced in this paper. The transmittance spectra show that average transmittance of devices is 68.0% (from 400 to 1100 nm) at bleached state and 26.1% (from 400 to 1100 nm) at colored state, respectively. And the maximal photopic transmittance of the device varies from 81.9% (bleached state) to 30.3% (colored state) at 736 nm. Compared with traditional devices, the spectral response range is improved obviously, which solves the problem of lower transmittance at bleached state for traditional devices.
