Colloidal Quantum Dots
Colloidal semiconductor quantum dots (QDs) have been widely used as sensitizers for photovoltaics and solar-driven wtare splitting thanks to their unique optoelectronic properties, such as a size tunable band gap, wide absorption, high absorption coefficients and multiple exciton generation.
With their nanometric size, such nanosctructures exhibit superior luminescent and absorption properties. Pi-SOL Technologies commercialize wide range of QDs including PbS, CdSe and CdS in different forms:
Colloidal core/shell quantum dots
Colloidal heterostructured quantum dots
