Perovskite Solar Cells (PSCs) have attracted considerable attention because of their unique features and high efficiency. However, the stability perovskite solar cells remains to be improved. In this study, we modified TiO 2 Electron Transport Layer (ETL) interface with PbCl . The efficiency car...

The two-dimensional mixed-valence tin oxide Sn3O4 with a low defect density of states and suitable energy band structure has shown great potential as the electron transport layer (ETL) for perovskite solar cells (PSCs). However, is should be modulated to demonstrate its application more efficient PSCs. Here, doped yttrium (Y) optimize electronic properties improve performance PSCs based on ETL....

Extraction-Transformation-Loading (ETL) tools are pieces of software responsible for the extraction of data from several sources, their cleansing, customization and insertion into a data warehouse. In this paper, we focus on the logical design of the ETL scenario of a data warehouse. Based on a formal logical model that includes the data stores, activities and their constituent parts, we model ...

In this paper, a 1.85V reduction in driving voltage of an OLED is presented by using an alkali-metal doped electron transport layer (ETL) and a silver (Ag) cathode. Such an ETL is composed of 2,9-dimethyl-4,7-diphenyl 1,10phenanthroline (BCP) doped with Cseium (Cs) to increase the conductivity of the organic material and achieve ohmic contact at the ETL/cathode interface regardless the work fun...

Openly available datasets originate from different data providers which range from government agencies, over commercial enterprises to communities of data enthusiasts. Integrating different source datasets into a single RDF graph by using ETL (Extract-Transform-Load) systems which perform offline transformation, ontology matching and linking techniques usually takes many iterations of revisions...
