单晶硅表面键合光敏染料的研究

80年代以来,随着半导体光电技术的飞速发展,光电器件在越来越多的领域中得到应用.但是,由于半导体材料本身性质上的限制,使其在光电转换及光谱响应范围等方面还存在着许多问题.例如,目前的硅太阳能电池,其光电转换效率已达17％,这与理论值21.6％已经很接近,要想突破21.6％的理论值,就必须寻求新的途径,彻底改变光电材料的性质.在单晶硅表面键合光敏染料,正是在这方面的一种探索.

STUDY ON THE CHEMICAL BOND OF THE PHOTOSENSITIVE DYES TO THE MONOCRYSTALLINE SILICON SURFACE

Since the 1980’s, with the rapid development of photoelectric semiconductor technology, photoelectric devices have been used in more and more fields. But due to the limit of the properties of semiconductor materials themselves, there are still many problems in photoelectric transform, spectral response range and so on. For example, the
