Abstract: A LiS battery includes a heterostructure deposited on a sponge of carbon nanotubes followed by annealing. The heterostructure may be performed by depositing layers of TiN and TiO2, such as TiN followed by TiO2. Following annealing, the TIN and TiO2 may be distributed substantially uniformly in the heterostructure. In some embodiments, the TiN layer has a thickness of 10 nm and the TiO2 layer has a thickness of 5 nm.

Abstract: A system and method for fabricating perovskite films for solar cell applications are provided, the system including a housing for use as a vacuum chamber, a substrate stage coupled to the top section of the housing; a first evaporator unit coupled to the bottom section of the housing and configured to generate BX2 (metal halide material) vapor; a second evaporator unit coupled to the housing and configured to generate AX (organic material) vapor; and a flow control unit coupled to the housing for controlling circulation of the AX vapor. The dimensions of the horizontal cross-sectional shape of the first evaporator unit, the dimensions of the horizontal cross-sectional shape of the substrate stage, and the relative position in the horizontal direction between the two horizontal cross-sectional shapes are configured to maximize the overlap between the two horizontal cross-sectional shapes.

Abstract: A system and method for fabricating a perovskite film is provided, the system including a housing for use as a CVD furnace having first and second sections coupled with first and second temperature control units, respectively. The first and second sections correspond substantially to the upstream and downstream of gases, respectively. One or more substrates are loaded in the second section and controlled by the second temperature control unit, and an evaporation unit containing an organic halide material is loaded in the first section and controlled by the first temperature control unit. Each of the substrates is pre-deposited with a metal halide material. The inside of the housing is pumped down to a low pressure.
