    摘要： Tailoring the emission spectra of a solar thermophotovoltaic emitter away from that of a blackbody, thereby minimizing transmission and thermalization loss in the energy receiver, is a viable approach to circumventing the Shockley-Queisser limit to single junction solar energy conversion. Embodiments allow for radically tuned selective thermal emission that leverages the interplay between two resonant phenomena in a simple planar structure—absorption in weakly-absorbing thin films and reflection in multi-layer dielectric stacks. A virtual screening approach is employed based on Pareto optimality to identify a small number of promising structures for a selective thermal emitter from a search space of millions, several of which approach the ideal values of a step-function selective thermal emitter

    摘要： An electrochemical cell that allows for in-situ structural characterization of amorphous thin film materials during the course of electrolysis using high-energy X-ray scattering (>50 keV). The compact and versatile cell employs a three-electrode configuration and minimizes X-ray scattering contributions from the cell, reference and counter electrodes, as well as the working electrode support. A large surface area working electrode has a physically robust support and is largely transparent to X-rays. This design, which utilizes a three-dimensional working electrode, also greatly improves the intensity and quality of the scattered signal compared to a two-dimensional working electrode. The in-situ cell can be used not only to investigate structural evolution during electrolysis using X-ray scattering (e.g. pair distribution function), but also to perform electrochemical potential-dependent structural analysis by extended X-ray absorption fine structure.

    摘要： An electrochemical cell that allows for in-situ structural characterization of amorphous thin film materials during the course of electrolysis using high-energy X-ray scattering (>50 keV). The compact and versatile cell, fabricated using a 3D printer, employs a three-electrode configuration and minimizes X-ray scattering contributions from the cell, reference and counter electrodes, as well as the working electrode support. A large surface area working electrode has a physically robust support and is largely transparent to X-rays. This design, which utilizes a three-dimensional working electrode, also greatly improves the intensity and quality of the scattered signal compared to a two-dimensional working electrode. The in-situ cell can be used not only to investigate structural evolution during electrolysis using X-ray scattering (e.g. pair distribution function), but also to perform electrochemical potential-dependent structural analysis by extended X-ray absorption fine structure. The in-situ electrochemical cell opens new opportunity to characterize amorphous thin films thinner than 70 nm.

    摘要： A method of protecting a perovskite halide film from moisture and temperature includes positioning the perovskite halide film in a chamber. The chamber is maintained at a temperature of less than 200 degrees Celsius. An organo-metal compound is inserted into the chamber. A non-hydrolytic oxygen source is subsequently inserted into the chamber. The inserting of the organo-metal compound and subsequent inserting of the non-hydrolytic oxygen source into the chamber is repeated for a predetermined number of cycles. The non-hydrolytic oxygen source and the organo-metal compound interact in the chamber to deposit a non-hydrolytic metal oxide film on perovskite halide film. The non-hydrolytic metal oxide film protects the perovskite halide film from relative humidity of greater than 35% and a temperature of greater than 150 degrees Celsius, respectively.
