EU Project ESPResSo to Make Perovskite Solar Cells a Market Reality
April 20, 2018 | ImecEstimated reading time: 3 minutes
Imec, a partner in EnergyVille, has been named the coordinator of an ambitious three-year European Union (EU) funded project, “ESPResSo” (Efficient Structures and Processes for Reliable Perovskite Solar Modules), that gathers known leaders in the field of perovskite PV technology to revolutionize Europe’s photovoltaics (PV) industry.
The ESPResSo consortium has been granted over 5M euro by the European Union to overcome the limitations of today’s state-of-the-art perovskite PV technology, bring perovskite solar cells to the next maturity level, and demonstrate their practical application. The members of the consortium include the fundamental research organizations Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland and Consiglio Nazionale delle Ricerche (CNR), Italy; perovskite solar cell scale-up and industrialization members imec, Belgium, Universita degli Studi di Roma Tor Vergata (UNITOV-CHOSE), Italy and Fraunhofer Institute for Solar Energy Systems ISE, Germany; and experts in sustainability and renewable energies CSGI (Consorzio Interuniversitario per lo Sviluppo dei Sistemi a Grande Interfase), Italy and University of Cyprus, Cyprus. Members representing materials development include Dycotec Materials LTD, United Kingdom, Dyenamo AB, Sweden and Corning SAS, France; equipment manufacturer, M-Solv LTD, United Kingdom; along with perovskite solar cell technology developers Saule Technologies, Poland, and building-integrated photovoltaics developer, Onyx Solar Energy SL, Spain.
With its low-cost materials and low temperature deposition processes, perovskite-based PV technology has the potential to takes its place in the thin-film PV market. Perovskite solar cells have already demonstrated high efficiencies (above 22%) that rival those of established mainstream thin-film PV technologies like copper-indium-gallium-selenide (CIGS) and cadmium-telluride (CdTe). The challenge is now to transfer the unprecedented progress that the perovskite PV cell technology has made in recent years from its cell level into a scalable, stable, low-cost technology on module level.
“Every aspect of our lives – from our homes to our workplaces, hospitals, schools and farms - depends on the nonstop availability of energy,” stated Tom Aernouts, imec group leader of thin-film photovoltaics and researcher at EnergyVille. “Perovskite cells demonstrate clear potential to support world’s energy demands cost-effectively. The ultimate aim of the partners of the ESPResSo project is to achieve this by bringing perovskite photovoltaics from the lab to the fab.”
The ESPResSo team targets alternative cost effective materials, novel cell concepts and architectures, and advanced processing know-how and equipment to overcome the current limitations of this technology. The consortium aims to bring the cell performance close to its theoretical limit by demonstrating cell efficiency of more than 24% (on 1cm²) and less than 10% degradation in cell efficiency following thermal stress at 85°C, 85% RH for over 1000h. Scale up activities utilising solution processed slot-die coating and laser processing will additionally deliver modules with more than 17% efficiency showing long-term (>20 years) reliable performance as deduced from IEC-compliant test conditions.
The ESPResSo team also envisions integrating modules in façade elements demonstrating a levelised cost of electricity (LCoE) of ≤ 0.05€/kWh. Prototyping advanced, arbitrary-shaped architectures with specific materials and process combinations will emphasize that new highly innovative applications like on flexible substrates or with high semi-transparency are well accessible in the mid- to longer-term with this very promising thin-film PV technology.

Trouble in Your Tank: Implementing Direct Metallization in Advanced Substrate Packaging
09/15/2025 | Michael Carano -- Column: Trouble in Your TankDirect metallization systems based on conductive graphite are gaining popularity throughout the world. The environmental and productivity gains achievable with this process are outstanding. Direct metallization reduces the costs of compliance, waste treatment, and legal issues related to chemical exposure. A graphite-based direct plate system has been devised to address these needs.
Closing the Loop on PCB Etching Waste
09/09/2025 | Shawn Stone, IECAs the PCB industry continues its push toward greener, more cost-efficient operations, Sigma Engineering’s Mecer System offers a comprehensive solution to two of the industry’s most persistent pain points: etchant consumption and rinse water waste. Designed as a modular, fully automated platform, the Mecer System regenerates spent copper etchants—both alkaline and acidic—and simultaneously recycles rinse water, transforming a traditionally linear chemical process into a closed-loop system.
Driving Innovation: Depth Routing Processes—Achieving Unparalleled Precision in Complex PCBs
09/08/2025 | Kurt Palmer -- Column: Driving InnovationIn PCB manufacturing, the demand for increasingly complex and miniaturized designs continually pushes the boundaries of traditional fabrication methods, including depth routing. Success in these applications demands not only on robust machinery but also sophisticated control functions. PCB manufacturers rely on advanced machine features and process methodologies to meet their precise depth routing goals. Here, I’ll explore some crucial functions that empower manufacturers to master complex depth routing challenges.
Trouble in Your Tank: Minimizing Small-via Defects for High-reliability PCBs
08/27/2025 | Michael Carano -- Column: Trouble in Your TankTo quote the comedian Stephen Wright, “If at first you don’t succeed, then skydiving is not for you.” That can be the battle cry when you find that only small-diameter vias are exhibiting voids. Why are small holes more prone to voids than larger vias when processed through electroless copper? There are several reasons.
The Government Circuit: Navigating New Trade Headwinds and New Partnerships
08/25/2025 | Chris Mitchell -- Column: The Government CircuitAs global trade winds continue to howl, the electronics manufacturing industry finds itself at a critical juncture. After months of warnings, the U.S. Government has implemented a broad array of tariff increases, with fresh duties hitting copper-based products, semiconductors, and imports from many nations. On the positive side, tentative trade agreements with Europe, China, Japan, and other nations are providing at least some clarity and counterbalance.
