摘要: In the research for innovative glazing, Dye Sensitized Solar Cells (DSSC) represent an interesting and effective way to achieve energy conversion and visual comfort by being wavelength selective for the NIR. In this context, our work aims to pave the way to selective NIR-sensitizers integrated into a new type of DSSCs being completely transparent and colorless in the whole visible region while harvesting light in the NIR where sunlight possesses ca. 40% of the photon flux and Human cones are not sensitive. Taking into account that the calculated wavelength cut-off to reach color neutrality corresponds to absorbance under 435nm and over 670nm, cyanine dyes represent the best candidates due to their capability to have a sharp and strong absorption in the NIR region without any significant residual in the visible. 1 This was demonstrated in our work on VG20 series dyes, where we reached a NIR-DSSC attaining …
