Colloidal quantum dots (CQDs) are tiny semiconductor particles that are just a few nanometers in size, which are synthesized in a liquid solution (i.e., colloid). These single-crystal particles, created by breaking down bulk materials via chemical and physical processes, have proved to be promising for the development of photovoltaic (PV) technologies.

Unlike conventional silicon-based solar cells, perovskite solar cells (PSCs) are not only thin and lightweight, but can also be seamlessly applied to curved surfaces, like building facades and vehicle roofs. What's more, they can be easily manufactured at room temperature using a solution process, leading to significantly reduced production costs.
