摘要
硅纳米晶体的电子和光学特性使其在改善太阳电池的性能方面扮演着重要角色。目前,硅纳米晶体在太阳电池中应用的主要方式有利用纯硅纳米晶体薄膜制作太阳电池、硅纳米晶体与无机(氧化硅、氮化硅或碳化硅等)或有机(P3HT)薄膜基质结合构成复合结构太阳电池、硅纳米晶体与碳纳米结构(富勒烯或单壁碳纳米管)结合形成复合结构、硅纳米晶体与传统的染料敏化太阳电池结合、利用硅纳米晶体的减反射或下转换作用将硅纳米晶体与体硅太阳电池结合。硅纳米晶体也有可能在新概念太阳电池如多激子太阳电池、中间带太阳电池和热载流子太阳电池中得到应用。
Silicon nanocrystals （Si NCs） are of great importance for the improvement of solar cell performance due to their remarkable electronic and optical properties. There are a variety of approaches to use Si NCs for solar cells. Si NC films, Si NCs embedded in organic（P3HT） or inorganic（SiO~, SiN~ or SiCk） matrices, Si NCs coupled with carbon nanostructures（C60 or single-walled carbon nanotubes） have been employed in the preparation of solar cells. The coupling of Si NCs with conventional solar cells such as dye-sensitized solar cells and Si-wafer-based solar cells has also been demonstrated. The exploration of Si NCs in the structures of novel multiple exciton solar cells, hot carrier solar cells and intermediate band solar cells has been started.
