EU funded - ESPResSo perovskite project starts

ESPResSo is an ambitious EU funded collaboration to make perovskite olar cells a market reality

Imec has been named project coordinator of a 3-year European Union (EU) funded project, "ESPResSo" (Efficient Structures and Processes for Reliable Perovskite Solar Modules), that brings together organisation from across the perovskite PV technology value-chain to "revolutionise" the European photovoltaics (PV) industry.

The announcements The ESPResSo consortium has been granted over €5 million 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 stage of maturity, and demonstrate their practical application.

The members of the consortium include the

Fundamental science research organisations

  • Ecole Polytechnique Federale de Lausanne (EPFL) (CH)
  • Consiglio Nazionale delle Ricerche (CNR) (IT)

Perovskite solar cell scale-up and industrialization members

  • imec (BE)
  • Universita degli Studi di Roma Tor Vergata (UNITOV-CHOSE) (IT)
  • Fraunhofer Institute for Solar Energy Systems ISE (DE)

Experts in sustainability and renewable energies

  • CSGI (Consorzio Interuniversitario per lo Sviluppo dei Sistemi a Grande Interfase) (IT)
  • University of Cyprus (CY)

Materials development

  • Dycotec Materials Ltd (UK)
  • Dyenamo AB (SE)
  • Corning SAS (FR)

Equipment manufacturer

  • M-Solv Ltd (UK)

Perovskite solar cell technology developers

  • Saule Technologies (PL)

Building-integrated photovoltaics developer

  • Onyx Solar Energy SL (ES)

According to the announcement - perovskite-based PV technology has the potential to takes its place in the thin-film PV market - due to its low-cost materials and low temperature deposition processes.

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 now is how to transfer the "unprecedented" progress that perovskite PV cell technology has made in recent years from its cell level into a scalable, stable, low-cost technology on module level.

The ESPResSo team aims are to 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 1000 hours.

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 emphasise 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.

"Every aspect of our lives – from our homes to our workplaces, hospitals, schools and farms - depends on the nonstop availability of energy."


"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."


Tom Aernouts, imec group leader of thin-film photovoltaics
