【摘要】：有機-無機雜化太陽電池綜合了有機、無機材料的優(yōu)點,成本低、理論效率高,受到人們的廣泛關(guān)注.雜化太陽電池的光活性層由無機半導體和有機共軛聚合物復合而成.當光照射到活性層上時,共軛聚合物吸收光子產(chǎn)生激子(電子-空穴對);激子遷移到有機給體-無機受體的異質(zhì)結(jié)界面處發(fā)生解離而產(chǎn)生自由電子和空穴;自由電子和空穴分別向無機半導體和有機聚合物傳輸,從而實現(xiàn)電荷的分離和傳導.激子在有機-無機異質(zhì)結(jié)界面處的分離效率是影響電池性能的一個重要因素.有機、無機兩相材料往往因為接觸面積小以及相容性差使此兩相材料接觸不佳,激子遷移到此界面不能有效分離,從而嚴重影響了雜化太陽電池的效率.這個問題可以通過此界面的修飾加以改善.本文即綜述了有機-無機異質(zhì)結(jié)界面修飾的方法、作用和意義,并展望了雜化太陽電池未來的發(fā)展趨勢和應用前景.
[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.
