【摘要】：有机-无机杂化太阳电池综合了有机、无机材料的优点,成本低、理论效率高,受到人们的广泛关注.杂化太阳电池的光活性层由无机半导体和有机共轭聚合物复合而成.当光照射到活性层上时,共轭聚合物吸收光子产生激子(电子-空穴对);激子迁移到有机给体-无机受体的异质结界面处发生解离而产生自由电子和空穴;自由电子和空穴分别向无机半导体和有机聚合物传输,从而实现电荷的分离和传导.激子在有机-无机异质结界面处的分离效率是影响电池性能的一个重要因素.有机、无机两相材料往往因为接触面积小以及相容性差使此两相材料接触不佳,激子迁移到此界面不能有效分离,从而严重影响了杂化太阳电池的效率.这个问题可以通过此界面的修饰加以改善.本文即综述了有机-无机异质结界面修饰的方法、作用和意义,并展望了杂化太阳电池未来的发展趋势和应用前景.
[Abstract]:Organic-inorganic hybrid solar cells integrate the advantages of organic and inorganic materials, low cost, high theoretical efficiency, The photoactive layer of hybrid solar cells is composed of inorganic semiconductors and organic conjugated polymers. The conjugated polymer absorbs photons to produce excitons (electron-hole pair), excitons migrate to the heterojunction of organic donor-inorganic receptors and dissociate to produce free electrons and holes. Free electrons and holes are transported to inorganic semiconductors and organic polymers, respectively, so as to achieve charge separation and conduction. The separation efficiency of excitons at the organic-inorganic heterojunction is an important factor that affects the performance of the cell, organic, organic, organic, organic, organic, organic, organic, organic, organic, organic, organic, organic, organic, organic. Due to the small contact area and poor compatibility, the contact between the two phase materials is not good, and the exciton migration to this interface can not be separated effectively. Therefore, the efficiency of hybrid solar cells is seriously affected. This problem can be improved by modifying the interface. In this paper, the methods, functions and significance of the modification of organic-inorganic heterojunction surface are reviewed. The future development trend and application prospect of hybrid solar cells are prospected.
