Abstract: Provided is a method for preparing a perovskite crystal that improves the performance of a photovoltaic cell. One embodiment of the present disclosure provides a method for preparing a perovskite crystal, the method including: a step S1 of preparing a perovskite solution containing a perovskite precursor and a first polar aprotic solvent; and a step S2 of preparing a perovskite crystal by mixing the perovskite solution and an antisolvent, wherein the antisolvent includes a second polar aprotic solvent.

Abstract: Disclosed are a system for providing hybrid user interfaces (UIs) which determines status information according to a subscriber terminal device and a service environment, and a suitable interaction mode corresponding to various content resources and UI resources through analysis of a user profile and provides a service suitable for a user and a situation through a combinative UI resource blended according to the interaction mode, and a method thereof. More particularly, by the system for providing hybrid UIs of the present disclosure and a method thereof, interaction modes corresponding to various content resources and UI resources may be organically combined in each of various set-top boxes and media devices, thereby providing stable and sustainable UIs.

Abstract: Disclosed are a system for providing cloud-based user interfaces and a method thereof. More particularly, a subscriber terminal device according to the present disclosure may include a control command receiver configured to receive a first control command including description information on a template repeated on a UI (User Interface) screen and a second control command including a replication command for the template from a remote application server; a template generator configured to generate a template the based on the description information on the template; a UI resource acquirer configured to acquire a UI resource based on the second control command; and a UI element generator configured to generate UI elements based on replication of the template and apply the UI resource to the UI element.

Abstract: Disclosed are a system for providing cloud-based user interfaces (UIs) which controls rendering of content and a UI resource by reusing a UI object stored in a subscriber terminal device, and a method thereof. By the system for providing cloud-based UIs of the present disclosure and the method thereof, the amount of a control command transmitted to the subscriber terminal device from a remote application server may be drastically reduced.

Abstract: Provided is a method and system for providing cloud based user interface (UIs) that may store video content and a UI resource in a storage separate from a server, and may control the video content and the UI resource to be synthesized at a subscriber terminal device, thereby significantly decreasing load of a UIs providing server. The method and system for providing cloud based UIs may provide consistent UIs to various set-top boxes and media devices and may easily perform a change and a test of UIs.
