Indoor light energy harvesting

Epishine’s indoor solar cells are the result of 30+ years experience of research in organic electronics and photovoltaics. Epishine LEHs are flexible and can be used alone or in conjunction with capacitors to replace batteries or prolong their lifetime in low-power applications.


Epishine's modules for light energy harvesting


Our modules can be purchased at:


  • Ideal for powering wireless indoor low-power applications, such as IoT devices, various sensors, etc.
  • Intended for use under indoor light conditions, e.g. office, supermarket, home, etc.
  • Flexible, compact, and lightweight design with 0.2 mm thickness.
  • Available in 6 standard sizes: 20, 30, and 50 mm with 6 or 8 cells.

Evaluation Kit

The evaluation kit is designed to show how our indoor solar cells can power wireless low-power devices that are normally powered by batteries. It combines Epishine LEH modules with an supercapacitor as an energy buffer and intelligent charging management to support various output voltages and energy storage solutions. It can even use an external primary battery as a backup.

The evaluation kit can deliver sufficient output current to power most low-power radios such as BLE, Zigbee, LoRa and similar. It is thin and flexible to showcase the unique product integration and design possibilities of Epishine's indoor solar cells

Lux Logger

One of the most important questions for our customers is how much light there is to harvest at the places where they intend to set up their devices. To help with the feasibility study, we have developed a small luxlogger suitable for understanding if there is enough light where your products normally are deployed. 


This product is currently not for sales separately, but can be rented in joint projects
