Epishine

What Epishine does

Epishine AB, founded in 2016 in Linköping, Sweden, develops and manufactures printed organic photovoltaic (OPV) solar cells engineered to harvest ambient indoor light. The company's core product is a thin, flexible, bifacial organic solar cell produced via a proprietary roll-to-roll printing process on PET substrates, where less than 0.1% of the 0.2mm cell thickness is semiconducting material. A patented two-substrate lamination process addresses microscopic defects that cause short circuits in low-light conditions, enabling operation at light intensities as low as 50 lux with up to 22 µW/cm² output and up to 90% conversion efficiency when paired with MPPT power management ICs. Epishine operates a 100-million-modules-per-year roll-to-roll production facility in Linköping, described as the world's most resource-efficient solar cell factory, with ISO 9001/14001/45001, REACH, and RoHS certifications.

Epishine sells cells on a B2B/OEM basis to manufacturers of low-power electronics who integrate them into their products, with no direct-to-consumer channel. The company targets four primary segments: smart buildings (CO2, temperature, humidity, and occupancy sensors), retail and logistics (electronic shelf labels and asset trackers), consumer electronics (remote controls, trackers, wearables), and broader IoT. Distribution is entirely OEM-embedded, supported by an ecosystem of technology partners — e-peas for PMICs, Nichicon for LTO batteries, NGK for thin Li-ion cells, tesa for adhesives — that co-develop reference modules and plug-and-play power solutions.

The company's commercial model is hardware sales of LEH-series cells to OEM customers at quote-based volume pricing, with multi-year supply contracts. Notable design-wins include the Google TV G32 remote control (via Ohsung Electronics, November 2025), SoluM rail-based ESLs, Pricer Avenue ESLs, Minew MTB11 asset trackers, MClimate CO2 displays, and several light-powered IoT sensor products from Greatech, Connected Inventions, Reef IoT, and inVirtus Technologies. Revenue is not publicly disclosed. Funding has totaled approximately SEK 165M+ across equity rounds (led by Jula Miljö & Energi) and EU/Swedish Energy Agency grants. The company employs 51-100 people across 17 nationalities.

Core offering

Epishine manufactures printed organic photovoltaic (OPV) indoor solar cells using a roll-to-roll printing process on flexible PET substrates, optimized for harvesting ambient indoor light at light levels as low as 50 lux. The cells are sold to OEMs and IoT device makers (e.g., Google TV remote controls, SoluM electronic shelf labels, MClimate CO2 sensors) for integration into low-power electronics, replacing disposable batteries. The company also offers integration design support and co-developed self-charging power modules such as the Nichicon SCB-Ep-Ni.

Product overview

Epishine offers a portfolio of printed organic indoor solar cells as its core product line, along with integration support services and sustainability documentation. The Indoor Solar Cell is the primary product — a thin, flexible, roll-to-roll printed organic photovoltaic cell that captures ambient indoor light and converts it to electrical power for low-power electronics. Integration services provide design support, technical documentation, and developer tools to enable product manufacturers to embed the solar cells into their devices. The Sustainability offering provides LCA data and environmental metrics to support customer ESG reporting. The portfolio also extends to a broad ecosystem of partner products that incorporate Epishine's solar cell technology — including remote controls (Google TV G32), asset trackers (Minew MTB11, inVirtus EosFlex), environmental sensors (MClimate CO2 Display, Greatech Sensoco, Reef IoT AIR-sense-IQ, Connected Inventions Airwits EcoSense), and electronic shelf label systems (SoluM rail-based ESL, Pricer Avenue) — all of which are powered by Epishine's indoor solar cells.
