  • Publication number: 20220187695
    Abstract: A method for preparing photoactive perovskite materials. The method comprises the steps of: introducing a lead halide and a first solvent to a first vessel and contacting the lead halide with the first solvent to dissolve the lead halide to form a lead halide solution, introducing a Group 1 metal halide a second solvent into a second vessel and contacting the Group 1 metal halide with the second solvent to dissolve the Group 1 metal halide to form a Group 1 metal halide solution, and contacting the lead halide solution with the Group 1 metal halide solution to form a thin-film precursor ink. The method further comprises depositing the thin-film precursor ink onto a substrate, drying the thin-film precursor ink to form a thin film, annealing the thin film; and rinsing the thin film with a salt solution.

  • Publication number: 20210021234
    Abstract: The performance of photosensitive devices over time may be tested by configuring a photosensitive device test system that includes a light source plate that exposes photosensitive devices within a container to a specified light intensity. The light intensity may be adjusted by a programmable power source according to one or more thresholds. A test may last for a set duration with performance measurements being taken at predetermined intervals throughout the duration. Feedback from the photosensitive device test system may be recorded to determine whether to increase light intensity, to stop testing, to continue testing, and whether one or more environmental conditions should be altered. Measurements may be sent to a client for analysis and display to a user.
