Sofies in collaboration with the solar PV research group of Christophe Ballif at EPFL and CSEM is happy to announce their latest world efficiency record for a silicon-perovskite tandem cell at 25.2%.
Researchers around the world are racing to increase the efficiency and return on investment of solar panels through the development of low-cost tandem solar cells capable of converting a larger part of the solar spectrum and . One of the most promising strategy today focuses on combining traditional silicon solar cells with low-cost, high efficiency perovskite solar cell.
Dr. Nicolas Tetreault of Sofies was key in developing the perovskite evaporation technique used to produce the near-infrared transparent perovskite solar cell with stable 16.4% performance. Combined with state-of-the-art silicon heterojunction solar cells developed in Prof. Ballif’s laboratories (EPFL PV-LAB, the team led by Jeremie Werner, Arnaud Walter, Bjorn Nielsen and Nicolas Tetreault was able to surpass previous efficiency records and bring this technology closer to market.
