A thin film （10 nm） of tris（8-quinolinolato）aluminum （Alq3） was adopted as the buffer layer. A device based on this DNP-2CN exhibited an open circuit voltage （Voc） of 370 mV, a short-circuit current density （Jsc） of 0.61 mAocm 2, and a white-light power conversion efficiency （ η） of 0.09% （AM1.5, 75 mW.cm^- 2）.展开更多

Through calculation, the uncertainty of the sample mainly came from Co standard uncertainty, weighing, uncertainty of volmne, effect on the recovery rate of sample during the course of extraction and purification and ucertainty from the random effect during the course of measurement. It was obtained that the expanded uncertainties of the content of 2 - naphthylamine, benzidine and 2, 4 - diaminotoluenc with higher frequency in 24 kinds of forbidden aromatic amines were respectively 2. 128, 2.302 and 4.778 mg/kg.展开更多
