Abstract: The disclosure discloses a perovskite film layer, a device and a preparation method for effectively improving the efficiency of perovskite optoelectronics. The perovskite film layer consists of a layer with discontinuous, irregularly distributed perovskite crystal grains and an organic insulating layer with a low refractive index embedded between the perovskite crystal grains. The perovskite crystal grains form a plurality of convex portions, and the organic insulating layer forms a plurality of concave portions between the convex portions. By adding an excess of an alkylammonium salt and/or an organic molecule with a specific functional group to perovskite precursor solution, a concave-convex film layer structure is spontaneously formed, and an upper charge transport layer and an electrode form pleated concave-convex structures.

Abstract: Systems and methods are disclosed for dynamically assigning a search head or search nodes in a data intake and query system for a query received by the data intake and query system. Existing search heads and search nodes can periodically report their status to the data intake and query system, which can use that information to help determine the need to provision additional search heads and search nodes. The data intake and query system can receive a query identifying a set of data to be processed and a manner of processing the set of data. The data intake and query system can use the status information for existing search heads and search nodes to dynamically assign a search head and search nodes for the query. Dynamically assigning the search head and search nodes in this manner may provide many benefits, including improved load balancing and resource utilization.
