Abstract: Materials and methods for preparing Cu2XSnY4 nanoparticles, wherein X is Zn, Cd, Hg, Ni, Co, Mn or Fe and Y is S or Se, (CXTY) are disclosed herein. The nanoparticles can be used to make layers for use in thin film photovoltaic (PV) cells. The CXTY materials are prepared by a colloidal synthesis in the presence of labile organo-chalcogens. The organo-chalcogens serves as both a chalcogen source for the nanoparticles and as a capping ligand for the nanoparticles.

Abstract: A method includes storing a copy of information, corresponding to a data set, in each of a plurality of data formats, and determining one or more portions of a search criterion to be associated with one or more sets of one or more characteristics. For each portion, based on the associated characteristics, a search is executed on a copy of information stored in a particular data format using a corresponding search algorithm to obtain a set of intermediary search results. A set of final search results corresponding to the search criterion is determined based on two or more sets of intermediary search results.

Abstract: A method for the preparation of CIGS-type core-shell nanoparticles produces core-shell nanoparticles that may include a quaternary or ternary metal chalcogenide core. The core may be substantially surrounded by a binary metal chalcogenide shell. A core-shell nanoparticle may be deposited on a PV cell contact (e.g., a molybdenum electrode) via solution-phase deposition. The deposited particles may then be melted or fused into a thin absorber film for use in a photovoltaic device.

Abstract: Various methods are used to provide a desired doping metal concentration in a CIGS-containing ink when the CIGS layer is deposited on a photovoltaic device. When the doping metal is sodium, it may be incorporated by: adding a sodium salt, for example sodium acetate, together with the copper-, indium- and/or gallium-containing reagents at the beginning of the synthesis reaction of Cu(In,Ga)(S,Se)2 nanoparticles; synthesizing Cu(In,Ga)(S,Se)2 nanoparticles and adding a sodium salt to the reaction solution followed by mild heating before isolating the nanoparticles to aid sodium diffusion; and/or, using a ligand that is capable of capping the Cu(In,Ga)(S,Se)2 nanoparticles with one end of its molecular chain and binding to sodium atoms with the other end of its chain.

Abstract: Techniques are herein described for creating a scalable IMAP4 compliant email system using a NoSQL database and a distributed full text search engine. Data for each email message is stored in multiple tables to avoid storing redundant data unnecessarily. However, a full text search index is created based on a single table as if the index refers to a single table. In embodiments herein described, the single index is created on the fields of a message metadata table with virtual fields added to the table that are derived from the message content. During this process, data is pulled from a message table in “blob” format and broken down into corresponding fields and data items, so the data items may be converted and placed in the proper virtual fields for index creation. Each blob section that is converted is cached, so the same blob section does not need to be converted multiple times. After index creation, the index may be used to search for emails based on metadata and data within the body of the email.

Abstract: A method for the preparation of copper indium gallium diselenide/disulfide (CIGS) nanoparticles utilizes a copper-rich stoichiometry. The copper-rich CIGS nanoparticles are capped with organo-chalcogen ligands, rendering the nanoparticles processable in organic solvents. The nanoparticles may be deposited on a substrate and thermally processed in a chalcogen-rich atmosphere to facilitate conversion of the excess copper to copper selenide or copper sulfide that may act as a sintering flux to promote liquid phase sintering and thus the growth of large grains. The nanoparticles so produced may be used to fabricate CIGS-based photovoltaic devices.

Abstract: The present disclosure provides a method and system for enabling the recall of messages. As an example, the method comprises receiving a message, where the message is created by a sender and configured to be sent to a recipient. The method further comprises identifying a first identifier for the message. The first identifier is configured to verify the sender of the message and enable a recall operation for the message. The recall operation results in the recall of the message, and the recall of the message involves cancelling the transmission of the message to the recipient or deleting the message.
