Infrared Photovoltaic–Battery Hybrid Systems Enabled by Colloidal Quantum Dots

Chemistry – An Asian Journal, EarlyView.
Photovoltaic–battery (PV/B) hybrid systems are key for sustainable energy but face cost and efficiency limits. Colloidal quantum dots (CQDs) enable low‐cost near‐infrared light harvesting, surpassing silicon and III–V PVs. This review analyzes CQD properties, their roles in NIR PVs and batteries, and synthesizes current research to highlight progress ...
