A bright future for solar cells
Yang Li
Developed in the early 1990s, dye-sensitised solar cells are a class of low-cost solar cells which have a layer of titanium dioxide coated with a light-harvesting sensitiser (dye). Peng Wang from Changchun Institute of Applied Chemistry, China, and Shaik Zakeeruddin and Michael Grätzel from Swiss Federal Institute of Technology, Lausanne, Switzerland, and colleagues have made a new sensitiser with a high extinction coefficient - meaning it is excellent at absorbing light.
The new sensitiser is a ruthenium complex with highly conjugated ligands containing thiophene rings. Preliminary tests using this sensitiser in a solar cell obtained a power conversion efficiency of 10.53 per cent, which is comparable with the 11.1 per cent achieved by the most efficient dye-sensitised solar cells reported to date. Grätzel says that this 'looks very promising'. This conversion may be lower than for commercially available silicon-based solar cells - at 20-25 per cent efficiency - but dye-sensitised solar cells are still desirable as they are more robust and intrinsically more stable than silicon-based solar cells.

虽然算不上顶级的文章，可以拿出来给大家看看啦，欣喜的是我们中国人也在里面充当了重要的角色，国内有不少课题组做这个方向，我以前的老板也把这个方向作为主要方向发展。从以前老田给我们讲了这个10%瓶颈，现在突破啦，所以这个方向还有大有"前"途的啊
