A roadmap for efficient and stable all-perovskite tandem solar cells from a chemistry perspective. ACS Central Science, 9(1), 14–26. https://doi.org/10.1021/acscentsci.2c01077https://doi.org/10.1021/acscentsci.2c01077https://hdl.handle.net/1828/20987Multijunction tandem solar cells offer a promising route to surpass the efficiency limit of single-junction solar cells. All-perovskite tandem solar cells are particularly attractive due to their high power conversion efficiency, now reaching 28% despite being made with relatively easy fabrication methods. In this review, we summarize the progress in all-perovskite tandem solar cells. We then discuss the scientific and engineering challenges associated with both absorbers and functional layers and offer strategies for improving the efficiency and stability of all-perovskite tandem solar cells from the perspective of chemistry.enAttribution 4.0 InternationalArticleDepartment of Chemistry
