A year after achieving what at the time was a world record efficiency for a tandem perovskite-silicon solar cell, scientists from EPFL and CSEM published a paper showing the technical features of the device and how that result was made possible. The key was regulating the perovskite crystallization process using an additive in the processing sequence.The Swiss Center for Electronics and Microtechnology (CSEM) and the École polytechnique fédérale de Lausanne (EPFL) announced in June 2022 they achieved a power conversion efficiency of 31.25% for a 1 cm2 tandem perovskite-silicon solar cell, which ...Den vollständigen Artikel lesen ...
