摘要:

有機(jī)-無機(jī)雜化體異質(zhì)結(jié)太陽電池以無機(jī)半導(dǎo)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(gè)研究熱點(diǎn)。在設(shè)計(jì)上，有機(jī)-無機(jī)雜化材料兼具有機(jī)材料的柔性、結(jié)構(gòu)多樣性、易加工和無機(jī)材料載流子遷移率高、穩(wěn)定性好的優(yōu)勢(shì)，具有良好的發(fā)展前景。本文介紹了有機(jī)-無機(jī)雜化體異質(zhì)結(jié)太陽電池的結(jié)構(gòu)、工作原理，從共軛聚合物、無機(jī)半導(dǎo)體納米材料以及電池制備工藝三個(gè)方面綜述了近年來國內(nèi)外研究現(xiàn)狀，主要包括有機(jī)-無機(jī)雜化體異質(zhì)結(jié)太陽電池中常用共軛聚合物結(jié)構(gòu)、帶隙，無機(jī)納米晶種類、形貌、表面改性以及有源層厚度、形貌調(diào)控等內(nèi)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(jī)-無機(jī)雜化體異質(zhì)結(jié)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.
