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