Dracula Technologies, headquartered in Valence, France, pioneers sustainable energy solutions with our LAYER® technology, revolutionizing power sources for low-power electronics. Our organic photovoltaic (OPV) modules, manufactured using patented digital printing, harvest ambient light, eliminating reliance on traditional batteries.
LAYER®Vault complements our existing OPV harvesting product line, transforming it into a 2-in-1 product, combining low-light energy harvesting and storage on a single, flexible film ensuring uninterrupted device functionality, empowering smart buildings, smart homes, smart asset tracking, electronic shelf labels, remote controls and other related applications.
With a commitment to clean, renewable energy, Dracula Technologies leads the charge towards a greener future by providing long-lasting, and cost-effective energy solutions.
- LAYER® LAB is the Research and Development division of Dracula Technologies, focused on designing prototypes and pre-series to materialize proof of concepts. Within LAYER® LAB, our team is dedicated to exploring new ideas, constantly pushing the boundaries of our OPV modules.
- The LAYER® Factory division is responsible for the large-scale production of LAYER® OPV modules. The factory is equipped with state-of-the-art equipment and experienced staff dedicated to ensuring that each module meets the highest standards of quality and performance.
- The LAYER® Solutions division offers IoT manufacturers and integrators turnkey products using our LAYER® product, offering a range of licensing options. We help developers design a standalone application and assist them with the implementation, delivery, and support of the final product.
LAYER® by Dracula Technologies is a groundbreaking energy-harvesting solution designed specifically for indoor IoT devices, delivering a sustainable, efficient, and customizable power source for low-power applications. Developed through over a decade of research and innovation, LAYER® uses organic photovoltaic (OPV) technology to convert ambient light into electricity.
This unique solution leverages a fully digital, inkjet printing process to create flexible, thin modules that can be tailored to any shape or size, enabling an endless variety of IoT applications without the need for batteries or cables.
LAYER®Vault by Dracula Technologies is an advanced 2-in-1 energy solution designed for IoT applications, combining ambient light energy harvesting with integrated storage on a single flexible film.
Thanks to our team’s many years of experience in integrating the elements of a device’s power supply, we can offer you our know-how to facilitate your transition to organic photovoltaic energy (OPV) and make your dream products a reality.
Eliminate batteries, use light to power your devices.
Large scale IoT for B2B is only viable when batteryless!

LAYER®
At Dracula Technologies, we offer an optimized device structure with exceptional performance. LAYER® is designed without a silver layer classically used in existing OPVs, which improves the absorption of light in the active layer, thereby optimizing the overall performance of the device.
Usually, an interfacial layer called Hole Transporting Layer (HTL) facilitates the extraction of holes from the active layer by the top electrode. In our configuration, the top electrode is specifically designed to ensure both extraction and collection of electrical charges.
- Working Temperature: -30°C to 60°C
- Thin: 0.30 mm
- Encapsulated: To protect from O₂ and H₂O
- Bifacial: It collects Photons from front and back
- Long-term stability: ~ 10 years (indoor condition)
- Freedom of design: Inkjet
- Light weight: 0.04 g/cm²
- Organic solution: From carbon based molecules and polymers
- Low cost: 1.2 € per unit for MOQ > 100 Ku
- Green solution:
- No toxic materials
- No toxic waste
- No halogenated solvents
- High recyclable rate
LAYER® is designed to generate energy in a broad spectrum of indoor settings, regardless of whether they are lit by natural or artificial light sources. Our solution excels in interior spaces with light levels ranging from 5 to 15000 lux.
Trust LAYER® to deliver energy even in challenging low-light conditions, ensuring optimal operation at all times for a wide range of indoor applications.
