Dracula Technologies will present Layer V2.0 at CES 2026, the next generation of its organic photovoltaic (OPV) technology, delivering a 30% increase in overall performance compared to the previous generation.

The company will present its latest innovation at CES 2026 Unveiled, before showcasing it throughout CES 2026 in the French Tech Pavilion, booth 60401.

Designed to address the growing demand for more efficient, compact, and sustainable power sources for connected devices, Layer V2.0 enables higher power output for the same surface area, or equivalent performance from a smaller module footprint. 

“With Layer V2.0, we are taking a major step forward in making light energy harvesting a practical and scalable power source for real-world IoT applications,” said Sadok Ben Dkhil, Chief Technology Officer at Dracula Technologies. “This new generation removes key limitations around size, performance, and cost, enabling more autonomous, durable, and sustainable connected devices without compromising reliability or design. With improved performance and new aesthetic options, OEMs now have greater freedom to integrate energy harvesting seamlessly into their products.”

This new generation gives OEMs greater design freedom while reducing size, cost, and reliance on disposable batteries. By delivering greater efficiency, flexibility, adaptability, and aesthetics, OPV modules bring durable and sustainable energy generation to a whole new range of IoT and smart sensor applications across industrial and consumer markets.

Performance Gain

The performance improvement in Layer V2.0 is driven by a new generation of proprietary OPV ink, engineered to combine enhanced light absorption with higher conversion efficiency. 

The ink is printed on a substrate using an inkjet printer that provides not just a durable and efficient active area layer but also the flexibility to support custom cell shapes and configurations at a volume scale. 

Together, these advances deliver a 30% overall performance increase, including under low indoor light conditions dominated by LED lighting.

Improved Aesthetics & Simplified Integration

Copper bus bars have been replaced with fine screen-printed silver bus bars, enabling simpler implementation of this part of the device using well-established industrial processes, while reducing inactive areas and delivering a more uniform visual appearance. 

This approach also preserves a high level of design flexibility, like the deposition of the other layers produced by inkjet printing, as only a simple tooling change is required for each new design. 

A new decorative top coating further enhances aesthetics and allows OEMs to select finishes adapted to their product design. This also makes it possible to design more discreet OPV devices and, above all, to provide greater robustness, including improved protection against scratches in applications where the product may be exposed to impacts or mechanical stress.

Next-Generation of Battery-Free IoT

By harvesting energy from ambient indoor light, whether natural or artificial, Layer OPV modules reduce or eliminate the need for disposable batteries in a wide range of applications.

With Layer V2.0, energy harvesting becomes viable for a broader set of use cases across asset tracking, smart buildings, industrial IoT, and consumer smart devices, enabling more autonomous systems with lower total cost of ownership.
