Solid-State Dye-Sensitized Solar Cells

Energy Harvesting Technology

Image:Solid-State Dye-Sensitized Solar Cells

The dye-sensitized solar cell (DSSC) is capable of generating high power even under weak light.
This technology is attracting widespread attention as an effective power source supporting the Internet of Things (IoT*) era, when everything is becoming connected.
Ricoh has developed a completely solid-state DSSC containing a solidified electrolyte, made possible through applying its organic photoconductor technology developed for multifunction printers (MFPs).
