Revolutionizing Indoor Solar Tech with Ligand-Passivated Quantum Dots

• Revolutionize indoor solar technology with ligand-passivated perovskite quantum dots, boasting enhanced stability and efficiency for self-powered optoelectronic devices.

Researchers from multiple universities have utilized ligand-passivation engineering to enhance the performance of indoor perovskite quantum dot photovoltaics. The inclusion of 2-phenyl-4-(1,2,2-triphenylvinyl) quinazoline (2PACz) in the perovskite quantum dot film resulted in a 35% increase in charge carrier lifetimes, leading to improved stability and efficiency.

The passivated perovskite quantum dot photovoltaics demonstrated an impressive output power density of 123.3 µW/cm2 with a power conversion efficiency of 41.1% under a fluorescent lamp. Additionally, the devices maintained over 80% of their initial efficiency for 500 hours in an ambient atmosphere, showcasing their potential for use in self-powered optoelectronic devices under dim illumination.
