Therefore, business transactions and analytics must co-exist together in a single platform to empower business users to drive insights, make decisions, and complete business processes in a single application and using a single source of facts without toggling between multiple applications. Traditionally transactional systems and analytics were maintained separately to improve throughput of the transactional system and that certainly introduced latency in decision making. However, with innovation in the SAP HANA platform, SAP S/4HANA embedded analytics enables business users, business analysts, and management to perform real-time analytics on live transactional data.

为了降低电子传输层(Electron transport layer,ETL)与钙钛矿层之间的界面缺陷态密度,通过旋涂法在氧化铟锡(Indium tin oxide,ITO)透明导电玻璃上制备一层SnO_(2)电子传输层,并在其上表面旋涂(NH_(4))_(2)S以修饰SnO_(2)和钙钛矿光吸...为了降低电子传输层(Electron transport layer,ETL)与钙钛矿层之间的界面缺陷态密度,通过旋涂法在氧化铟锡(Indium tin oxide,ITO)透明导电玻璃上制备一层SnO_(2)电子传输层,并在其上表面旋涂(NH_(4))_(2)S以修饰SnO_(2)和钙钛矿光吸收层之间的界面。通过X射线光电子能谱、扫描电子显微镜、电化学阻抗谱等表征手段分析(NH_(4))_(2)S修饰对钙钛矿太阳能电池(Perovskite solar cells,PSCs)光电性能的影响。结果表明:NH_(4)^(+)降低了SnO_(2)的表面羟基(—OH)缺陷态密度,增强了界面的疏水性,减少了钙钛矿的形核位点,增大了钙钛矿晶粒;S^(2-)填补了SnO_(2)表面的氧空位(OV),同时部分S^(2-)还与未配位Pb^(2+)连接减少界面处Pb缺陷,抑制了界面处载流子复合;经过(NH_(4))_(2)S的修饰,PSCs开路电压从1.07 V提高到1.11 V,光电转化效率达到了20.53%。(NH_(4))2S修饰后的PSCs具有更高的光电转化效率、更好的长期稳定性。该研究可为PSCs商业化提供新的思路。展开更多
