Low-Cost Flexible Solar Panels for Buildings, Vehicles, and Smart Devices

energyTestedTRL 5

Imagine a solar panel that is as flexible as a sheet of plastic and can be printed like a newspaper. Instead of heavy glass and expensive metals, it uses a special crystal material and carbon ink to capture sunlight. This makes solar power light enough to wrap around a car or blend into a building wall without needing heavy supports.

The business problem

What needed solving

Traditional silicon solar panels are heavy, rigid, and expensive to install on non-flat surfaces. This limits solar adoption in the automotive and architectural sectors where flexibility and aesthetics are required.

The solution

What was built

A scalable manufacturing process for flexible perovskite solar cells using carbon electrodes, utilizing gravure printing and slot-die coating.

Who can put this to work

Construction
enterprise
Target: BIPV (Building Integrated PV) manufacturer

If you are a building materials company dealing with the weight and rigidity of silicon panels — this project developed flexible perovskite cells that allow for aesthetic, customized solar integration into walls and roofs with production costs below 0.3 EUR/Wp.

Automotive
enterprise
Target: Electric Vehicle (EV) OEM

If you are a car manufacturer dealing with the difficulty of fitting rigid panels on curved vehicle surfaces — this project developed flexible solar cells that can be integrated into the bodywork to extend battery life while keeping emissions below 0.01 kg CO2eq/kWh.

Electronics
SME
Target: IoT device manufacturer

If you are a smart-sensor company dealing with short battery life in remote devices — this project developed lightweight, printable solar cells that can power small electronics without the need for bulky traditional panels.

Frequently asked

Quick answers

What is the target production cost for these solar cells?

The project aims to lower production costs to below 0.3 EUR/Wp.

Can this technology be produced at an industrial scale?

Yes, the project focuses on high-throughput fabrication using industrially viable methods such as gravure printing and slot-die coating.

Who owns the IP and how is licensing handled?

Based on available project data, specific licensing terms are not listed, but the consortium includes 10 partners across 8 countries, including 3 industry players.

How does the environmental impact compare to traditional PV?

The use of carbon electrodes instead of vacuum-deposited metals significantly reduces the CO2 footprint, targeting emissions below 0.01 kg CO2eq/kWh.

When will the results be finalized?

The project period runs from 2023-10-01 to 2027-03-31.

Consortium

Who built it

The consortium is well-balanced for commercialization, consisting of 10 partners from 8 countries. With a 30% industry ratio (3 companies, including 2 SMEs), there is a strong bridge between the 7 research and university entities and the actual market, ensuring that the high-throughput fabrication methods are grounded in industrial reality.
