摘要:

有機-無機雜化體異質結太陽電池以無機半導體納米晶作為電子受體，共軛聚合物作為電子給體，是近年來的一個研究熱點。在設計上，有機-無機雜化材料兼具有機材料的柔性、結構多樣性、易加工和無機材料載流子遷移率高、穩(wěn)定性好的優(yōu)勢，具有良好的發(fā)展前景。本文介紹了有機-無機雜化體異質結太陽電池的結構、工作原理，從共軛聚合物、無機半導體納米材料以及電池制備工藝三個方面綜述了近年來國內外研究現狀，主要包括有機-無機雜化體異質結太陽電池中常用共軛聚合物結構、帶隙，無機納米晶種類、形貌、表面改性以及有源層厚度、形貌調控等內容。著重介紹了基于CdSe、TiO2、PbS類納米晶的太陽電池。最后討論了有機-無機雜化體異質結太陽電池目前存在的問題和發(fā)展方向。

Abstract:

Organic-inorganic bulk heterojunction(BHJ) solar cells which consist of conjugated polymers as electron donors and inorganic semiconductor nanocrystals as electron acceptors , have attracted extensive research in recent years. They combine the advantages of organic materials and the inorganic counterparts, that is the flexibility, design capability and easy-processing of organic materials as well as high charge mobility and good stability of inorganic ones, and have good prospects for development. In this article, we first explain the structure and general working principles of organic-inorganic BHJ solar cells and then review the recent developments of conjugated polymer, inorganic materials and device preparation process, including chemical structure and bandgaps of common polymers, morphology and surface modification of inorganic nanocrystals and control of active layer thickness and morphology. CdSe、TiO2、PbS nanocrystals based organic-inorganic BHJ solar cells are mainly introduced . Finally, we discuss the problems of organic-inorganic solar cells and their future developments.
