Heavy-Metal-Free Quantum Dot Inks for Thin-Film Tandem Solar Cells
Prof. Oleksandr Voznyy
(Department of Physical and Environmental Sciences, University of Toronto)
Abstract
Tandem solar cells are a promising route to increase the efficiency of solar cells. They require semiconductor materials with a bandgap wider than that of silicon, and ideally not contain heavy metals. Due to the vacuum processing of conventional III-V materials, their price remains an order of magnitude higher than that of silicon. We propose to utilize colloidal quantum dot (CQD) inks to achieve scalable and low-cost solution processing of the state-of-the-art photovoltaic materials.
In this talk, I will summarize our recent progress in developing sintered CuInS2 QD films and potential ways to further improve their electronic properties. I will also discuss the application of machine learning for optimizing the synthesis of quantum dots, as well as computational predictions of new promising heavy-metal-free photovoltaic and optoelectronic materials.
