摘要：奥迪、宝马、奔驰已经分别在国内投产,隶属于福特旗下的VOLVO品牌也憋不住,想分一杯羹。作为三点式安全带的发明者,其车系向来给人饱满、扎实、稳健的感觉,其安全性更是毋庸置疑。动感外型经过大改款的S40,其外型设计融入许多巧思,以前保险杠来说,左右两侧经过切削、内缩的线条（共4页)

摘要：To date, the cost-effective utilization of solar energy by photovoltaics for large-scale deployment remains challenging. Further cost minimization and efficiency maximization, through reduction of material consumption, simplification of device fabrication as well as optimization of device structure and geometry, are required. The usage of 1D nanomaterials is attractive due to the outstanding light coupling effect, the ease of fabrication, and integration with one-dimensional(1-D) semiconductor materials. The light absorption efficiency can be enhanced significantly, and the corresponding light-toelectricity conversion efficiency can be as high as their bulk counterparts. Also, the amount of active materials used can be reduced. This review summarizes the recent development of 1-D nanomaterials for photovoltaic applications, including the anti-reflection, the light absorption,the minority diffusion, and the semiconductor junction properties. With solid progress and prospect shown in the past 10 years, 1-D semiconductor nanomaterials are attractive and promising for the realization of high-efficiency and low-cost solar cells.
