 Vibrant DSSC dyes


Dyenamo offers a series of aesthetic dyes suitable for semi-transparent dye-sensitized solar cell (DSSC) devices. Dyes in various colors, blue, green, orange, red and yellow, are available as standard materials. Other colors are available on demand. The final color of the DSSC device depends on additional factors than the dye, such as the electrolyte and the TiO2 film. Electrodes for making semi-transparent DSSC devices can be obtained on demand.

Dyenamo Blue 2016 YD2 Dyenamo Yellow (L0)
Dyenamo Blue Dyenamo Transparent Green Dyenamo Cloudberry Orange
DPP13     Dyenamo Orange (D35)
Dyenamo Mareel Blue     Dyenamo Red (D35CPDT)

The shown colors are just illustration of the dye's appearance. The actual color of a device depends on various factors such as electrolyte, substrate, concentration of the dye and others.

DN-F10M

Dyenamo Blue 2016



DN-F10M_small
Description:
Dyenamo's second in-house developed organic blue dye for high-performance esthetic DSSC devices. Dyenamo's experience of DN-F10 and DN-F10M is that they deliver very similar DSSC device performance and stability. However, out of these two dyes, DN-F10M is more cost-efficient in production and thus offered at a lower price and in larger quantities.

Description:
During 2012 and 2013, Dyenamo Orange (D35) has been established worldwide as a reference organic dye for DSSCs. Excellent device stability has been obtained both under light and after at least 1000 h storage in darkness at temperatures of 85°C. The absorption spectrum of D35 makes it interesting also for indoor application due to a good match with fluorescent light. Moreover, it has been concluded that Dyenamo Orange (D35) is an excellent choice for see-through DSSC devices, due to high performance, good stability (also at 85°C), and an attractive orange color.
