Nanoscale Advisory Board member Professor Zhiqun Lin presents this Editor’s Choice collection focusing on perovskite nanomaterials and devices.

“The past several years have been witness to an unprecedented advance in perovskite-based materials and devices. This new class of materials possess a set of superior optoelectronic properties, including tuneable direct band gaps, large absorption coefficient, high ambipolar mobility, long carrier diffusion lengths, small exciton binding energy, and high defect tolerance. In this context, it is pertinent to compile this themed issue centring on recent rapid development in the field of perovskite-based materials and devices for the solar energy conversion research community. To this end, we have collected an array of high-quality research articles and reviews recently published in Nanoscale. We hope that the readers find this themed collection informative and useful.”
