The present disclosure relates to a composition that includes a first layer that includes a perovskite and a second layer that includes a perovskitoid, where the perovskite has a first crystalline structure defined by ABX, the perovskitoid has a second crystalline structure defined by A'BX, where A is a first cation, B is a second cation, X is an anion, and A′ is a third cation having either a 1+ charge or a 2+ charge.

Compositions and methods for modifying perovskite surfaces

The present disclosure relates to a device that includes a first layer having an active material and a stabilizing material, where the active material includes a semiconductor, the stabilizing material includes at least one of an oligomer, an elastomer, a polymer, and/or a resin, and the stabilizing material provides to the device an improved performance metric compared to a device constructed of the first layer but constructed of only the active material (i.e., in the absence of the stabilizing material).

A method for calculating a current illumination level of a target scene capable of quantitatively evaluating an illumination level in a scene through a camera, and a method for automatically adjusting an illumination level of the target scene capable of automatically performing a constant light control over a scene, and a camera, capable of quantitatively evaluating the illumination level in the scene and a smart illumination control system are provided. The smart illumination control system is capable of quantitatively evaluating the illumination level in the scene and automatically adjusting an illumination brightness, a color temperature, a color or a contrast in the scene to realize a constant control over a light environment. In addition, by setting the illumination level on a setting terminal, an illumination product also performs a light-supplementing automatically for the camera to realize a constant light control over a shooting.

A method for rapidly and quantitatively adjusting a beam angle of an illuminating device includes: determining a target beam angle according to an actual scene, and sending, by using an input apparatus, the target beam angle to the illuminating device; receiving, by a receiver of the illuminating device, the target beam angle and sending the target beam angle to a controller of the illuminating device; determining, by the controller of the illuminating device, target power of each light source according to the target beam angle and a parameter table stored in a local read-only memory (ROM) or cloud of the illuminating device; and driving, by a driver, each light source to emit light according to the corresponding target power, enabling radiated light to be mixed in an illuminated space to change the beam angle, and obtaining the target beam angle according to a superposition principle for the intensity of light.

The present disclosure relates to a method that includes applying a first perovskite precursor solution to a substrate to form a first liquid film of the first perovskite precursor solution on the substrate; from the first liquid film, forming a first intermediate solid perovskite layer on the substrate; repeating at least once, both the applying and the forming, resulting in the creation of at least one additional intermediate solid perovskite layer; and treating a last intermediate solid perovskite layer, resulting from the at least one additional applying and the at least one additional forming, to create a final solid perovskite layer.

Methods for producing perovskite-containing devices

Provided is a method for preparing a carbon nanotube/polymer composite material, including: coating a nano-silicon oxide film on the surface of a porous polymer by vacuum coating; depositing a metal catalyst nano-film on the nano-silicon oxide film by vacuum sputtering; growing a carbon nanotube array in situ on the surface of the porous polymer by plasma enhanced chemical vapor deposition to obtain a carbon nanotube/polymer porous material; and impregnating the carbon nanotube/polymer porous material with a polymer and curing to obtain the carbon nanotube/polymer composite material. By using a heat-resistant polymer having a high heat-resistant temperature and a PECVD technique, a carbon nanotube array directly grows in situ on the surface of a polymer at a low temperature, which thereby overcomes the defects of the composites previously prepared, in which carbon nanotubes are difficult to be homogeneously dispersed and the interfacial bonding force in the composites is weak.
