Imec, a research and innovation hub in energy, nanoelectronics, and digital technologies and partner in EnergyVille was named the coordinator of a project intended to Perovskite solar cells commercially viable. The ambitious 3-year European Union (EU) funded project ESPResSo (Efficient Structures and Processes for Reliable Perovskite Solar Modules), brings together known leaders in the field of perovskite PV technology.
The European Union has granted the ESPResSo consortium over 5M euros to overcome the performance and reliability limitations of state-of-the-art perovskite PV technology. With relatively low-cost materials and a low-temperature deposition process, Perovskite solar cells hold the promise of eventually being inexpensively made solar cells. However, they have been plagued by issues of reliability and so far have not been very competitive in conversion efficiency. This ESPResSo project intends to overcome these issues, and demonstrate the practical application of Perovskite solar cells.
The members of the ESPResSo consortium includes perovskite solar cell scale-up and industrialization members imec, Italy and Fraunhofer Institute for Solar Energy Systems ISE, Germany, and Belgium, Universita degli Studi di Roma Tor Vergata (UNITOV-CHOSE); experts in renewable energies and sustainability the University of Cyprus, Cyprus, and CSGI (Consorzio Interuniversitario per lo Sviluppo dei Sistemi a Grande Interfase), Italy. Additional members of the consortium include a list of materials development companies.
The consortium intends to raise perovskite cell performance close to its theoretical limit by demonstrating cell efficiency of more than 24% (on 1cm²) with less than 10% degradation in cell efficiency following thermal stress at 85°C, 85% RH for over 1000h. Scale-up activities include using solution processed slot-die coating and laser processing to fabricate cells with more than 17% efficiency showing long-term (>20 years) reliable performance as projected from IEC-compliant test conditions.
