- Additional information
- This work, funded by Innovate UK, showed for the first time that the manufacturer-provided leakage current of the supercapacitor can be directly used for storage estimation of the PV energy harvesting in IoT applications. This has the potential to boost the wide use of supercapacitors in the IoT market worth hundreds of billions of USD, for example through the safe replacement of the Lithium battery (e.g. CP 1254 50 mAH, 1µA leakage) with a supercapacitor (e.g. 5.4V 0.5F, 2 µA leakage) for indoor PV energy storage, achieving a five-fold increase in lifetime in addition to reduced cost.
