Doping Colloidal Quantum Dot Materials and Devices for Photovoltaics

Colloidal semiconductor nanocrystals have generated tremendous interest because of their solution processability and robust tunability. Among such nanocrystals, the colloidal quantum dot (CQD) draws most attention for its well-known size effects. In last decade, applications CQDs been booming in electronics optoelectronics, especially photovoltaics. Electronically doped semiconductors are critical fabrication solar cells, carefully designed band structures able to promote efficient charge extraction. Unlike conventional semiconductors, diffusion ion implantation technologies not suitable doping CQDs. Therefore, researchers creatively developed alternative methods CQD materials devices. order provide a state-of-the-art summary comprehensive understanding this research community, we focused on various techniques photovoltaics demystify them from different perspectives. By analyzing two classes CQDs, lead chalcogenide perovskite compared working scenarios each technique, summarized development field, raised our own future
