Epishine Selects CAP-XX High Efficiency Supercaps for Thin Indoor Light Energy Harvesting Solution

Epishine’s light energy harvesting evaluation module uses ultra-thin CAP-XX supercap for energy storage to demonstrate how manufacturers can eliminate batteries in small, low-power devices

Sydney, Australia – February 16, 2021 – CAP-XX Limited (LSE:CPX), the leading manufacturer of ultra-thin prismatic and cylindrical supercapacitors, announced that Sweden-based Epishine, a leading manufacturer of printed organic solar cells, has selected the CAP-XX GA230 supercapacitor for its indoor light energy harvesting (LEH) evaluation module. The module demonstrates how Epishine’s indoor light energy harvesting cells, when combined with a thin CAP-XX supercap, can power indoor wireless sensors, electronics, IoT devices and other low-power devices that are normally powered by batteries.

The new Epishine/CAP-XX/e-peas indoor light energy harvester LEH3 evaluation module features Epishine’s 50 x 50mm photovoltaic indoor light cell to harvest ambient indoor light, a high-efficiency CAP-XX 3.5mm thin 400mF GA230 supercapacitor to store the harvested energy, and the e-peas AEM10941 energy harvesting power management integrated circuit (PMIC) for intelligent supercap charging and overall system power management. Once indoor light energy is harvested and stored in the supercap, it can power electronics and IoT devices when light is not available, can serve peak energy demands of the device, and can either eliminate the need for a battery or prolong battery life in typical low-power applications.

“A supercap is essential for storing Epishine’s harvested light energy to keep devices operational when indoor light is unavailable,” said Marco Ranalli, general manager of CAP-XX Europe. “We share Epishine’s mission to enable battery-free products worldwide through environmentally-conscious energy harvesting, as our supercapacitors are made of non-hazardous, common materials like activated carbon and aluminum.”

Intended for indoor light environments, the compact evaluation module (81 x 71.5 x 3.8mm) contains everything needed for manufacturers to test if the solution will generate enough energy to power their devices without a battery. Supporting output voltages ranging from 1.8V to 3.3V, the solution can deliver sufficient output current to power most low-power radios such as BLE, Zigbee and LoRa.

Epishine, CAP-XX and e-peas will present a webinar, ‘Eliminate Batteries with Indoor Light Energy Harvesting and Supercaps,” on March 3 at 5pm CET (4pm GMT, 11am ET, 8am PT). To register go to:


“Our goal is to enable sustainable solutions, from both an environmental and maintenance perspective, by eliminating the need for battery replacement,” said Mattias Josephson, vice president of business development and co-founder of Epishine. “We chose the CAP-XX supercapacitor for our evaluation module for its amazing charge efficiency and thin profile to enable devices with small form factors.”

“By combining the low-light performances of Epishine’s new photovoltaic indoor light cell, our AEM10941 energy harvesting PMIC, and the CAP-XX ultra-thin supercap, the LEH3 evaluation module is ideal for easily evaluating the opportunity to implement light energy harvesting for indoor IoT products,” said Geoffroy Gosset, CEO of e-peas.
