| Popis: | 101 This study combine with p-i-n and tandem structure to obtain the p-i-n tandem structure OLED.Because of the tandem structures which are composed of p-type (F4-TCNQ) and n-type (HAT-CN) doped layers in common,we can connect two p-i-n units structure and take the p-n junction as interlayer.Some research topics are included in this research : (1) Study of carrier generation and other optoelectronic characteristics for tandem cells. (2) Study of different p-typed and n-typed concentration doped to basic structure. The results shows that concentration of F4-TCNQ and HAT-CN will affect optoelectronic characteristics.And we final find the best concentration of HAT-CN(50%) to obtain the high efficiency p-i-n tandem structure with max current efficiency 16.2 cd/A and power efficiency 1.8 lm/W . |
