Energy Harvesting for Wireless Sensors
Energy harvesting wireless switches and sensors collect small amounts of energy from their environment. These sensor nodes often use proprietary protocols or more standard protocols such as EnOcean or Zigbee Green Power. With the event of ultra low power electronics many sensors can harvest tiny amounts of light from their surroundings, enabling them to register, detect and transmit information wirelessly.
These technical breakthroughs reduce the energy needed to transmit a signal. As a result, energy harvesting wireless sensors can work where other technologies can not.
Energy harvesting wireless switches and sensors can now be deployed and operate inside buildings where lighting levels are extremely low using a solar photovoltaic cell as the power source.
SolarPrint’s Products as an Energy Harvesting Solution
The market leading product for indoor PV-powered applications is the Amorphous Silicon (Am-Si) module. SolarPrint has developed a uniquely configured patented DSSC module tailored for indoor light environments, leveraging the known benefits of the technology to produce a commercially desirable device.
DSSC has the highest power density energy conversion of any solar PV technology that operates within ambient and diffuse light environments. Today this out performance ranges between 40% to 50% more power per square cm of surface area right up to over 300% more power depending on the lighting intensity making it the solar PV of choice for many wireless applications.
