Technoeconomic Model Suggests Scaling-Up Perovskite Quantum Dots for Optoelectronics Warrants Improved Synthesis Yield, Solvent Recycling, and Automation

Colloidal quantum dots (QDs) are nanometer-sized semiconductor crystals grown via low-cost solution processing routes for a wide array of applications encompassing photovoltaics, light-emitting diodes (LEDs), electronics, photodetectors, photocatalysis, lasers, drug delivery, and agriculture. A comprehensive technoeconomic cost analysis of perovskite quantum dot optoelectronics is reported. Using economies-of-scale considerations based on price data from prominent materials suppliers, we have highlighted that increased QD synthesis yield, solvent recycling, and synthesis automation are critical to market adoption of this technology and driving quantum dot film fabrication costs down from >$50/m^2 to ∼$2−3/m^2
