A severe limiting factor in the development of perovskite/c-Si tandems to date has been their inferior light-harvesting ability compared to single-junction c-Si solar cells, but recent innovations have made impressive headway on this front. Here, we provide a quantitative perspective on future steps to advance perovskite/c-Si tandem photovoltaics from a light-management point of view, addressing key challenges and available strategies relevant to both the 2-terminal and 4-terminal perovskite/c-Si tandem architectures. In particular, we discuss the challenge of achieving low optical reflection in 2-terminal cells, optical shortcomings in state-of-the-art devices, the impact of transparent electrode performance, and a variety of factors which influence the optimal bandgap for perovskite top-cells. Focused attention in each of these areas will be required to make the most of the tandem opportunity.Australian Renewable Energy Agency; Australian Research Council; Bundesministerium für Bildung und Forschung (PRINTPERO); the Initiating and Networking funding of the Helmholtz Association; the European Union’s Horizon2020 program (ACTPHAST); Karlsruhe School of Optics & Photonics (KSOP); Swiss National Science Foundation via NRP70 Energy Turnaround PV2050 and Swiss National Science Foundation Bridge (176552) projects.application/pdfen-AU© 2019 American Chemical SocietyPhotovoltaicsPerovskite solar cellsPerovskite-silicon tandem solar cells2019-05-2210.1021/acs.jpclett.8b03721
