Quantum dot in perovskite hybrids for photovoltaics: Progress and perspective

Abstract

Colloidal quantum dots (CQDs) are receiving great attention as promising nanomaterials for optoelectronic applications due to their unique electronic properties and straightforward processability. Despite extensive global research and significant progress in the surface chemistry and device architecture of CQDs, meeting the future demands for stability and device performance continues to be a challenge. Recently, innovative matrix engineering strategies that introduce a dot-in-perovskite structure have been recognized as breakthroughs in overcoming these challenges. This review chronicles the advancements of CQD-perovskite hybrids and discusses future perspectives, particularly regarding lead sulfide (PbS) CQDs for infrared photovoltaic applications. © 2024 Author(s).
