Photovoltaic cells
printed
The perovskite-based solar cells designed by GTSA, unlike silicon photovoltaic cells which require energy-intensive, high-temperature processes, use a low-cost, low-temperature manufacturing process compatible with flexible polymer substrates. This technology, still under development, combines advantages in terms of cost, energy consumption, environmental friendliness, flexibility and energy sovereignty.
GRAPHENATON Technologies SA has validated the structure of its solar cells and obtained promising results in the laboratory. The company is now focusing on improving long-term stability, optimizing efficiency and industrializing on a large scale.
Integration adapted to structures
Printed on thin, flexiblesubstrates , perovskite solar cells open up new possibilities for the building industry. They can be easily adapted to the curvature of elements to match the design of the structure. Perovskite photovoltaics is an emerging thin-film technology. For overa decade, perovskite solar cells have achieved record laboratory yields, exceeding 25% efficiency, rivaling silicon in many applications. Its unique features include high performance under various lighting conditions, andnegligible thickness and weight.

Integrated heating for transport
The trend towards electrification will have an impact on both vehicle design and the environment in which they travel. Solar cells integrated into car bodies or photovoltaic tarpaulins on trucks will improve their energy efficiency and reduce their carbon footprint.

Economical
and sustainable
Printing solar cells significantly reduces manufacturing costs by avoiding complex requirements such as a controlled atmosphere and high-temperature silicon purification, and requires fewer rare materials, making production more accessible and sustainable.

Energy-efficient and committed to the energy transition
Printed cells are manufactured at much lower temperatures (120°C vs. over 1,000°C for silicon), which reduces the energy footprint of the process. Unlike traditional methods, this approach generates fewer rejects and reduces the need for toxic waste treatment.

Flexible and adapted to new energy requirements
Unlike rigid solar panels, these ultra-thin, flexible cells can be adapted to a wide range of surfaces such as smart buildings and electric vehicles, and their modularity opens the way to innovative applications in portable electronics and urban integration.
Clean, independent energy production without structural constraints
Our photovoltaic cell films incorporating Graphene and Perovskite are designed to ultimately capturesolar energy to generateelectricity without CO₂ emissions. Unlike conventional panels, they will be ultra-thin, lightweight and flexible. These films will integrate easily on various surfaces - buildings, vehicles or curved structures - without structural constraints, optimizing energy recovery.
Designed from emerging materials such as Perovskites and Graphene, our films will free themselves from the limitations of silicon, notably its recyclability issues and heavy dependence on the Chinese market, which dominates silicon photovoltaic production.
Thanks to a leaner manufacturing process, these photovoltaic films considerably reduce their ecological impact, while offering a sustainable, high-performance alternative to traditional solutions.
FAQ
Photovoltaic films developed by GRAPHENATON Technologies SA exploit Perovskite thin films printed on flexible substrates to convert light into electricity with high efficiency and low resource consumption.
Graphene is used as an ultra-thin conductive layer, facilitating the transport of electrical charges and improving the device's durability and flexibility.
Thanks to their ultra-thin, flexible design, these photovoltaic cells can be integrated into buildings, vehicles and portable electronic devices. Their excellent sensitivity to diffuse light guarantees efficient energy production even in low-sunlight conditions.
Photovoltaic cell films from GRAPHENATON Technologies SA offer several advantages:
- Flexibility: they can be integrated into curved or lightweight supports.
- Lightweight: much thinner than traditional solar panels.
- Low-light efficiency: capture energy even on overcast days.
- Discreet integration: suitable for buildings, transport and connected objects.
Our photovoltaic films reduce their ecological impact thanks to low-temperature manufacturing (120°C compared with over 1,000°C for silicon), considerably reducing the carbon footprint of the process.
Moreover, the use of Graphene and Perovskite limits the consumption of rare earths and facilitates recycling, unlike silicon panels, which require energy-intensive processing and present environmental challenges linked to material extraction and recycling.
