February 27 (Renewables Now) - Belgian nanotechnology research group Imec and partners in the PERCISTAND consortium have for the first time achieved an energy efficiency of 25% with a thin-film solar cell, matching the efficiency of a traditional silicon solar cell, according to a statement released on Wednesday.
After hitting this record, the consortium has yet to reach the upper limit of its thin-film solar cells, coordinator Bart Vermang said. The goal is to reach an energy efficiency of 30% within the coming three years, he added.
The cell that achieved this record efficiency consists of two layers. Part of the companies in the consortium are working on the bottom cell and others on the top cell. However, the consortium is still working to find a way to bring them together in a module cost-efficiently.
The PERCISTAND research project received EUR 5 million (USD 5.5m) in funding as part of the European Horizon 2020 programme. The consortium includes Imec, Hasselt University, Belgium-based VITO, Dutch TNO, Zentrum fuer Sonnenenergie- und Wasserstoff-Forschung Baden-Wuerttemberg, Karlsruhe Institute of Technology, Empa Switzerland, National Centre for Scientific Research – Institute PV France (CNRS-IPVF), Solar Switzerland, NICE Solar Energy, Australian National University and National Renewable Energy Laboratory USA.
