Fujikura DSSCs (Dye‐Sensitized Solar Cells)

Fujikura DSSCs Solve These Problems

Fujikura DSSCs make battery-free sensor terminals a reality. The time and effort associated with battery replacement is becoming more evident as IoT sensing expands, its applications become more diverse, and the number of sensor terminals increases. DSSCs that can generate power in all environments can be used in a wide variety of situations.

445/5000 Cost and Labor Encountered in Battery Replacement in Sensor Terminals are Important Issues in IoT Adoption

Modernization and automation initiatives using IoT detection are being developed in a variety of situations around us. While inexpensive, easy-to-install, battery-powered sensor terminals are used for proof of concept, when it comes to practical application, the cost and labor that accompany battery replacement become important issues in adoption.

Usage Scenarios

As the installation of IoT terminals expands and increases in number, initial setup costs and post-adoption battery replacement costs decrease drastically.

Features

  • Feature 1: High power generation over a wide range of lighting conditions

    Capable of generating electricity anywhere: in sunlight, in shade, in bad weather, indoors, etc.

  • Feature 2: High power generation over a wide range of temperatures

    Capable of supplying electricity from -30°C to +60°C, an even wider range than normal batteries can deliver

  • Feature 3: Can be installed without regard to the position of the light source

    Since power can be generated from scattered light, there is no need to make sure the cells are oriented toward the light source

  • Feature 4: It is okay for part of the DSSC to be in shadow

    These cells avoid the problems that most multiple series solar cells can experience due to shadows

  • Feature 5: Durable enough to be used both indoors and outdoors

    While durability is said to be an issue with DSSCs, our cells are durable enough for long-term power supply without needing to worry about installation location.

Feature : Capable Of Generating Electricity Anywhere In The Living Environment

High power generation over a wide range of lighting conditions

Capable of generating electricity anywhere: in sunlight, shade, poor weather conditions, indoors, etc.

High power generation over a wide range of temperatures

Capable of supplying electricity from -30°C to +60°C , an even wider range than normal batteries can deliver

Feature : Terminals With Built In DSSCs Are Easy To Install

No need to consider the position of the light source

Since power can be generated from scattered light, there is no need to make sure the cells are oriented toward the light source

It is okay for part of the DSSC to be in shadow

These cells avoid the problems that multiple series solar cells can experience due to shadows

This video shows an experiment that places part of the DSSC in shadow -> There was almost no drop in power output like that which was observed for multiple series solar cells in the same experiment. (The figure at right shows power fluctuation)

Durable enough to be used both indoors and outdoors

While durability is said to be an issue with DSSCs, our cells are durable enough for long-term power supply without considering installation location
