Doped Quantum Dots for Solar Cell Applications: A Step Toward Environmental Sustainability

ABSTRACT Nanotechnology has massively revolutionized almost every industry on global scale. Quantum dots, typically in the range of 2‐10 nm are artificial nanocrystalline semiconductors that have emerged as a promising frontier in the field of fluorescent nanomaterials. Their unique advantages, including high photostability, brightness, and narrow emission, make them the most promising option for use in many biological imaging, biosensing applications, and display technology. Various synthetic routes are reported in literature that affect their size, composition and applications consequently. Quantum dots doped with apt elements show significant progress in photovoltaic performance, thus making them a favorable material for next‐generation solar cells. The development of doped quantum dots is thoroughly examined in this review, which also provides an updated summary of the photovoltaic applications of doped quantum dots, highlighting notable increase in power conversion efficiency (PCE). This is anticipated to boost opportunities in the field of renewable energy sources and represent a positive step toward environmental sustainability.
