Semiconducting colloidal quantum dots (QDs) have garnered great attention for photovoltaics due to their unique properties, including decoupled crystallization from film deposition, size-tunable bandgap, multiple exciton generation, etc. Nanometer-sized colloidal metal halide perovskite QDs have emerged and brought unique opportunities for photovoltaic application due to the high defect tolerance of perovskite and many features that emerge at the nanoscale. Perovskite QDs or more broadly, nanocrystals, show high photoluminescence (PL) quantum yields, spectrally tunable bandgap, flexible compositional control, and crystalline strain benefits. Metal halide perovskite QDs are readily synthesized with exceptional optoelectronic quality opening a route for next generation photovoltaic, as well as exploring LHP physics at the nanoscale.
Since the first report in 2016, perovskite QDs also became a point of interest in photovoltaic research. Currently FAPbI3 QD holds the record efficiency for QD solar cells (over 19%) proving better than any previous QD material composition. This talk will highlight the importance of high-efficiency perovskite QD solar cells, from synthesis to device fabrication. We will discuss current state of the art and lay out many open opportunities in perovskite QD solar cells to achieve approaching 20%, as well as the design and synthesis of conductive perovskite QD ink toward high-efficiency and fast printable solar cells.
