Tandem Perovskite Photovoltaics

Research in perovskite-based tandem photovoltaics has emerged as a promising technology and made tremendous breakthroughs in recent years. While high efficiencies have been achieved in perovskite/silicon tandem devices, the long-term stability of the perovskite active layer remains a major challenge for their commercialisation. It is therefore important to take an interdisciplinary approach to expedite the development and deployment of tandem solar cells based on perovskite materials.

In this collection at Nature Communications, Communications Materials, Communications Physics and Scientific Reports, we aim to bring together cutting-edge perovskite/silicon tandems, all-perovskite tandems, and hybrid perovskite tandems crossing multidisciplinary areas, and invite commentaries from experts. Topics of interest include but are not limited to the following:

• Materials and fundamental research for practical tandem devices
• Device architecture design, upscaling and manufacturing
• Characterisation and modelling
• Stability, reliability, accelerated and outdoor testing
• Sustainability, reproducibility and recycling

We welcome the submissions of primary research that fall into any of the above-mentioned categories. All the submissions will be subject to the same peer review process and editorial standard as regular Nature Communications, Communications Materials, Communications Physics and Scientific Reports articles.

This Collection supports and amplifies research related to SDG 7.
