Imagine a solar panel that is as thin as a sticker, can be bent, or even lets light through like a window. This project creates a new type of solar cell that is much cheaper to make and doesn't use toxic liquids during production. It's designed to last for decades while being easy to recycle at the end of its life.
Current high-efficiency solar cells often rely on toxic solvents during production and lack the flexibility or transparency needed for integrated urban use. Additionally, the long-term stability and lead leakage of perovskites pose significant environmental and regulatory risks.
A range of vacuum-deposited perovskite solar cells (rigid, flexible, and semi-transparent) and specialized encapsulation materials to prevent lead leakage.
If you are a glass manufacturer dealing with the need for energy-generating windows — this project developed semi-transparent solar cells with over 50% visible light transmission and over 10% efficiency. This allows buildings to generate power without blocking the view.
If you are a device maker dealing with rigid, heavy battery packs — this project developed flexible perovskite absorbers and substrates. This enables the integration of power sources directly into curved surfaces or clothing.
If you are a solar company dealing with high production costs and toxic solvent waste — this project developed vacuum-deposited cells that avoid harmful solvents and target efficiencies above 26%. This reduces environmental liability and improves energy yield.
Based on available project data, the project focuses on low-cost manufacturing processes and lifecycle costing (LCC) to ensure economic viability, though specific price points per watt are not provided.
Yes, the project specifically targets scalable production processes using vacuum and hybrid processing to eliminate toxic solvents, moving beyond lab-scale solution processing.
Based on available project data, a patent has already been applied for an electron transport molecule capable of self-assembling on a suitable surface.
The project aims for an extrapolated operational lifetime of more than 25 years, validated through outdoor test facilities in three different European locations.
The project developed encapsulation methods using lead-chelating materials to contain lead even in broken modules and a full end-of-life recovery process for circularity.
The consortium is well-balanced for commercialization, featuring 14 partners across 9 countries. With a 36% industry ratio (5 industrial partners, including 3 SMEs), the project bridges the gap between academic research (5 universities, 4 research organizations) and market application, ensuring that the developed vacuum-processing techniques are industrially viable.
