    摘要： A method for preparing photoactive perovskite materials is provided. The method comprises the step of preparing a BiX 3-y X' y precursor ink. Preparing a BiX 3-y X' y precursor ink comprises the steps of: introducing BiX 3-y X' y into a vessel, introducing a first solvent to the vessel, and contacting the BiX 3-y X' y with the first solvent to dissolve the BiX 3-y X' y . The method further comprises depositing the BiX 3-y X' y precursor ink onto a substrate, drying the BiX 3-y X' y precursor ink to form a thin film, annealing the thin film, and rinsing the thin film with a second solvent and a salt.

    摘要： 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.
