A colloidal quantum dot solar cell is fabricated by spray‐coating under ambient conditions. By developing a room‐temperature spray‐coating technique and implementing a fully automated process with near monolayer control—an approach termed as sprayLD—an electronic defect is eliminated resulting in solar cell performance and statistical distribution superior to prior batch‐processed methods along with a hero performance of 8.1%.
