Perovskite Quantum Dots for Photovoltaic Applications

2020
Perovskite solar cell with easy solution processing and high efficiency has been considered as a promising photovoltaic technology, but the material instability makes it questionable for practical applications. Perovskite quantum dots (QDs) provide new possibilities to resolve these concerns.

Efficient Luminescence from Perovskite Quantum Dot Solids

ACS Applied Materials & Interfaces, 2015
Nanocrystals of CsPbX3 perovskites are promising materials for light-emitting optoelectronics because of their colloidal stability, optically tunable bandgap, bright photoluminescence, and excellent photoluminescence quantum yield. Despite their promise, nanocrystal-only films of CsPbX3 perovskites have not yet been fabricated; instead, highly ...

Colloidal Quantum Dot Photovoltaics Enhanced by Perovskite Shelling

Nano Letters, 2015
Solution-processed quantum dots are a promising material for large-scale, low-cost solar cell applications. New device architectures and improved passivation have been instrumental in increasing the performance of quantum dot photovoltaic devices. Here we report photovoltaic devices based on inks of quantum dot on which we grow thin perovskite shells ...

Superabsorption in CsPbBr3 Perovskite Quantum Dots

Proceedings of the Materials for Sustainable Development Conference (MATSUS Fall 24)
Absorption of light via interband optical transitions constitutes a primary process in nature, e.g., in photosynthesis, as well as in applied technologies, e.g., in solar photovoltaic cells, photodetectors, or (quantum) light-matter interfaces. In cavity-free systems, engineerability of the rate of absorption has thus far been limited, consistent with ...

Perovskite Quantum Dots and Their Application in Light‐Emitting Diodes

Small, 2017
AbstractPerovskite quantum dots (PQDs) attract significant interest in recent years because of their unique optical properties, such as tunable wavelength, narrow emission, and high photoluminescence quantum efficiency (PLQY). Recent studies report new types of formamidinium (FA) PbBr3 PQDs, PQDs with organic–inorganic mixed cations, divalent cation ...
