LUMINOSITY Project kicked-off

On 1st June 2024, the LUMINOSITY project officially has launched. Coordinated by TNO, this industry-driven initiative aims to scale flexible perovskite solar cell (PSC) technology to commercially relevant production levels using established industrial processes.

Over the next four years, the consortium will work to demonstrate roll-to-roll (R2R) processed photovoltaic (PV) modules with a power conversion efficiency (PCE) of over 20% on an area greater than 900 cm², aiming to bridge the efficiency gap between lab-scale and fab-scale devices and elevate the Technology Readiness Level (TRL) to 7.

A standout feature of this project is the commercial substrate foil based on aluminum with a fluorinated-tin-oxide (FTO) electrode layer, an intellectual property of HyET Solar, the project’s end user. By using this substrate foil, LUMINOSITY will alleviate the bottlenecks related to limited process window of typical polymer substrate foils – such as high-quality nickel oxide charge transport layer deposition – to reach high stability, efficiency, and lower environmental impact, while keeping the flexibility.

To achieve LUMINOSITY’s ambitious goals, a multidisciplinary consortium has been assembled, featuring 15 partners from 10 European countries, including Switzerland. These members bring strong innovation and industrial experience to the project, ensuring the objectives and milestones are met.
