Bifacial perovskite/silicon tandem solar cells

Perspective Year: 2022 DOI:https://doi.org/10.1016/j.joule.2022.05.014

Authors: Michele De Bastiani, Anand S. Subbiah, Maxime Babics, Esma Ugur, Lujia Xu, Jiang Liu, Thomas G. Allen, Erkan Aydin, Stefaan De Wolf

Michele De Bastiani and colleagues address the main challenges of bifacial perovskite/silicon tandem solar cells in their last perspective published in Joule. Bifacial tandems are a great innovation to combine stability and performance at once, bringing the perovskite technology one step closer to its commercialization.
