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).

Features

High power output in areas with low light.

With excellent power generation efficiency in low lighting environments such as near office walls, and in warehouses and factories,
RICOH DSSCs provide power for IoT devices, such as those operating on coin cell batteries, eliminating the need for battery replacement.

Safety with a solidified electrolyte

RICOH has succeeded in completely solidifying the electrolyte.
The solidified electrolyte eliminates the risk of leakage due to aging, ensuring safety and high durability.

A wide range of operating temperatures

RICOH EH DSSCs maintain high power output from -30 °C to 60 °C.They can be used in refrigerated and frozen environments, as well as in an indoor environment.
