Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.

Thiolated gold nanoclusters: A new class of photosensitizers

The past several decades have seen major advancements in the synthesis of metal nanomaterials. Most recently, controlled synthesis has become versatile enough to regulate the exact number of atoms and ligands of very small metal nanoparticles, referred to as “clusters”.

Ultra-High Efficiency Perovskite-Perovskite Tandem Solar Cells

Next generation solar cells have the potential to achieve conversion efficiencies beyond the Shockley-Queisser (S-Q) limit while also significantly lowering production costs.

Recent Advances in Hybrid Halide Perovskites-based Solar Cells

For several decades, the need for an environmentally sustainable and commercially viable source of energy has driven extensive research aimed at achieving high efficiency power generation systems that can be manufactured at low cost.
