Compact Button-Cell-Less ESL: Light-Powered Display Using Organic Photovoltaics

Reading time : 2 min | 12/09/2025

Technical Product Sheet

This compact Electronic Shelf Label (ESL) operates without traditional button-cell batteries, relying entirely on Organic Photovoltaics (OPV) to harvest indoor ambient light.
The OPV module, integrated behind the display, captures natural and artificial light to deliver a continuous and battery-free energy supply, without altering the ESL’s compact form factor.

Leveraging the advantages of Organic Photovoltaics, this system enables a fully sustainable power architecture designed for low-consumption retail applications. It eliminates battery replacement cycles, reduces maintenance costs, and minimizes environmental impact while ensuring stable operation under typical indoor lighting conditions.

This technical datasheet provides detailed information on OPV-driven power management, mechanical design parameters, electrical performance metrics, integration constraints, and compatibility guidelines for engineering teams seeking to deploy long-life, maintenance-free ESL solutions.
