In recent years, the performance of organic thin-film solar cells has gained rapid progress, of which the power conversion efficiencies (ηp) of 3%-5% are commonly achieved, which were difficult to obtain years ago and are improving steadily now. The ηp of 7.4% was achieved in the year 2010, and ηp of 9.2% was disclosed and confirmed at website of Mitsubishi Chemical in April, 2011. The promising future is that the ηp of 10% is achievable according to simulation results. Apparently, these are attributed to material innovations, new device structures, and also the better understanding of device physics. This article summarizes recent progress in organic thin-film solar cells related to materials, device structures and working principles. In the device functioning part, after each brief summary of the working principle, the methods for improvements, such as absorption increment, organic/electrode interface engineering, morphological issues, are addressed and summarized accordingly. In addition, for the purpose of increasing exciton diffusion efficiency, the benefit from triplet exciton, which has been proposed in recent years, is highlighted. In the active material parts, the chemical nature of materials and its impact on device performance are discussed. Particularly, emphasis is given toward the insight for better understanding device physics as well as improvements in device performance either by development of new materials or by new device architecture.

与单一结构相比,有机嵌段异质结构具有特殊的光电性能.然而,有机分子间的相互作用主导了异质结构构建单元的生长顺序,如有机单元A、B会自发形成BAB型结构而不是相反的ABA型结构,不能可控生长.在此,我们提出了次序结晶工程,结合晶种逐步自组装,控制共晶R与共晶N在彼此的两端纵向外延生长,从而精确合成具有可逆嵌段构型的有机嵌段异质结构:RNR和NRN. RNR有机嵌段异质结构,由于其逐渐掺杂的异质结而表现出渐变色的发射和波导特性,而NRN有机嵌段异质结构由于其明显的构筑异质结界限而表现出纯双色发射和波导特性.本工作实现了有机嵌段异质结构中嵌段块的有序可控生长,为未来光子学发展提供了制备合理复杂有机嵌段异质结构的途径.

Weighted occupation time processes associated with the super-Brownian motions on hyperbolic spaces are investigated. Longtime behavior and a central limit type theorem for the processes are obtained. For all dimension d≥2, the right normings for two fluctuations are t and t1/2 , and the limit results are the Riemannian measure and some centered Gaussian random measure, respectively.

The influence of higher-order effects on the transmission performances of the ultra-short soliton pulses and its suppression method

引用

Science china(Information Sciences) 2010年第1期53卷 182-190页

作者： ZHU Bo & YANG XiangLin institute of Optical Communication, nanjing university of posts and telecommunications, nanjing 210003, china institute of Optical Communication Nanjing University of Posts and Telecommunications Nanjing China

Under the condition of the higher order effects, a propagation equation is established to investigate the way to suppress the soliton self frequency shift and timing jitter in the picosecond and femtosecond soliton communication system using a combined control method of time domain and frequency domain. By the use of the variational approach, the evolution of the chirping Gaussian quasi-soliton pulse is analyzed in the presence of the effects including third order dispersion, intrapulse Raman scattering (IRS), and self steepening. Considering the soliton evolution properties and the mechanism of the timing jitter under the higher-order effects, the combined control method is adopted to eliminate the influence from Raman scattering and self-steepening. The soliton central frequency is stabilized and the timing jitter is suppressed effectively. A 160 Gb/s long-haul soliton transmission system is designed and its performance is numerically simulated. The simulation results are in good agreement with our theoretical analysis.

关键词： high rate soliton communication higher-order nonlinearity Raman self-frequency shift transmission control stable transmission
