Perovskites, with their wide bandgap range, are good partners for both commercial and novel photovoltaic technologies in multijunction solar cells. Here, McGehee and co-workers review recent material and device developments and highlight future challenges and opportunities for perovskite-based tandems.
Perovskites for Optoelectronics
Perovskite materials have become very promising candidates for a new generation of potentially printable and efficient optoelectronic devices. As of 2018, progress has been made in improving the stability and scalability of perovskite-based single-junction and tandem solar cells, thanks to better mastering of synthesis methods and optimization of device architectures. Exploration of the detection properties well beyond the visible spectrum continues, as well as the use as emitters. Open questions remain on the optoelectronic processes taking place in metal halide perovskites, triggering further investigation of the physics of these materials.
This web-collection brings together an editorially-curated selection of multi-disciplinary research articles published in the Nature journals that explore the basic properties of halide-based perovskite materials and their potential for application in optoelectronics, from solar cells to lasers.
In addition to Research Articles, the collection gathers Comments and selected News and Views published since January 2015 in the News and comments section and Perspectives and Review articles under Reviews. Historical milestones on the synthesis and characterization of hybrid organic-inorganic metal halide perovskites and their use in applications are reported in the Milestones section.
This collection was initially published online in September 2016, and was updated in September 2017 and September 2018.
