Colloidal quantum dots (CQDs) are versatile solution-processable nanocrystals which have great promise for optoelectronic applications. Among the properties that make them unique are the large spectral tunability, the outstanding monodispersity, the solution processability and the good transport properties in thin films. Due to the quantum confinement effect, CQDs give rise to large variations in the bandgap. When using Pb chalcogenides the NIR and part of the visible spectra can be covered, which make them very interesting for many optoelectronic applications among which solar cells.  After a brief introduction to the physical properties of colloidal QDs, the state of the art and challenges in colloidal QD solar cells will be discussed.
