This guest editorial introduces the special series on Perovskite-Based Solar Cells.

This special series of the Journal of Photonics for Energy focuses on the science and technology of the so-called perovskite-based solar cells. These materials have been named for their perovskite crystal structure that adopts an ABX3 composition, where for example A = formamadinium-FA, methylammonium-MA, Cs, and/or Rb; B=Pb2+, and/or Sn2+; and X=Cl, Br, and/or I. These materials have gained a lot of attention due to rapid rise in performance, reaching current record certified efficiencies of 22.1%.1 In spite of their quickly achieved high efficiencies, there is still much to learn about the synthesis and properties of these materials. Here we display a series of new findings and perspectives on a variety of related topics.

The collection of papers were published in the Journal of Photonics for Energy, throughout Volumes 6 and 7:

, Soosaimanickam Ananthakumar et al. https://doi.org/10.1117/1.JPE.6.042001 provide a review of the synthesis, properties, and applications for cesium lead halide perovskite quantum dots (QDs). These QDs have higher quantum yield (90%) than any other semiconductor QDs making them a promising candidate for a variety of device applications. Since this report researchers have reported CsPbI3 QD devices with a certified device efficiency of 13.43%,2 a current QD device record. , Alex Hariz https://doi.org/10.1117/1.JPE.6.032001 and , Zhaoning Song et al. https://doi.org/10.1117/1.JPE.6.022001 present two perspective views on perovskite-based solar cells and provide commentary on potential pathways to higher performance.

The articles in this special series provide a snapshot of the rapidly advancing field of perovskite-based solar cells. We hope these works provide inspiration for new areas of research while also providing a perspective outlook on this exciting field.
