| 2 | Germinant ZnO nanorods as a charge-selective layer in organic solar cells显示文摘A facile method was introduced and demonstrated to synthesize zinc oxide(ZnO) nanorods(NRs) as an electron transporting layer(ETL) for organic solar cells(OSCs).Hydrothermal synthesis of the NRs showed a constant growth rate of 5.5 nm min-1 from germination to sub-micrometer length.The properties were characterized using scanning electron microscopy(SEM),transmission electron microscopy(TEM),absorption spectrophotometry and so on.Based on these measurements,the germinant growth mechanism and its corresponding orientation characteristics were investigated.As an ETL of the OSCs,ZnO NRs enhance the charge extraction from the active layer due to their increased interfacial surface area,but there is an optimal length because of the shunt path formation and UV absorption of long ZnO NRs.As a re sult,the OSC with the ZnO NRs as ETL shows power conversion efficiency(PCE) up to 6.2%.The J-V characteristics and incident photon-to-current conversion efficiency(IPCE) measurement also reveal that the efficiency enhancement is an assembly of individual results from optical,physical and electrical characteristic of the ZnO NRs. | Kunsik An Jaehoon Kim Mohammad Afsar Uddin Seunghyun Rhee Hyeok Kim Kyung-Tae Kang Han Young Woo Changhee Lee | 2020 | Journal of Materials Science & Technology2020，52，20： | 1 |
| 3 | Investigation of Nickel Oxide Used for Alloying in BOF Steelmaking显示文摘Direct alloying of nickel oxide in a hot simulator of LD converter was investigated in laboratory.Reduction rate of nickel oxide in steelmaking process was analyzed with the test results. Under the condition oflower slag viscosity, the reduction rate of NiO increases and the [Ni] yield rises. When the slag viscosity is higher, a lot of metal particles with higher Ni content are contained in the slag so as to decrease the [Ni] yield. | CHEN Weiqing ZHOU Rongzhang HUH Wanwook RHEE Changhee(Faculty of Metallurgy, USTB, Beijing, 100083, China)(Research Institute of Industrial Science and Technology, Pohang, Korea) | 1997 | International Journal of Minerals,Metallurgy and Materials1997，11，1： | 0 |
