About this Research Topic
This Research Topic on Quantum Dot Solar Cells is focused on the synthesis, characterization and modeling of semiconductor quantum dots (QDs) and metal halide perovskite nanocrystals (PNCs) and their application as light harvesting materials in solar cells.
A fundamental goal of this article collection is the development of novel approaches towards QDs and PNCs of controlled dimensions, compositions, shapes, and surface chemistries and their integration into different solar cell device configurations. QD- and PNC-based solar cells have seen a spectacular performance evolution in recent years with power conversion efficiencies exceeding 13%. One of the key advantages of using quantum dots for solar cells is the possibility to precisely tune their optical, structural, and electronic properties prior to device integration. Furthermore, they allow for a large variety of shapes to be realized, their synthesis can be easily scaled up, and they can be simply and cost-effectively integrated into devices using solution processes. Therefore, nanocrystals are expected to play a major role in leveraging long-standing bottlenecks related to device stability, efficiency, and the replacement of toxic heavy metals.
