Optimizing Colloidal Quantum Dot Synthesis Conditions for Tandem CQD Solar Cells

Program:

Electrical and Computer Engineering

Project Description:

Tandem solar cells are of interest as a route to improve efficiencies beyond the limitations of current single junction cells (such as silicon solar cells). Fabricating a tandem solar cell requires introducing a new semiconductor material with a different bandgap, which will absorb a different portion of the sun’s spectrum. In this poster, we synthesize lead sulfide colloidal quantum dots (PbS CQDs) of different bandgaps and explore their applications in tandem solar cells.
