摘要:

全球性的環境與能源危機已成為可持續發展必須面臨的重要問題，開發清潔可再生能源以替代傳統化石能源成為當今社會關注的焦點之一。其中，利用太陽能電池將太陽能轉化為電能是清潔可再生能源領域最有前景的解決方案。在眾多太陽能電池技術中，有機太陽能電池因具有質量輕、原材料來源廣泛、成本低、機械柔性好、可采用濕法制備成大面積器件等優勢而備受關注。開發高性能的電子給、受體材料以及界面材料是進一步提升有機太陽能電池光電轉換效率的關鍵。其中，金屬絡合物因其較高的三線態激子密度、較長的激子壽命以及較高的熒光量子產率而引起廣泛的研究興趣。近年來，金屬絡合物材料越來越多地被用在有機太陽能電池中，并使器件獲得了較高的性能。從金屬絡合物的給體材料、受體材料、添加劑以及界面材料4個方面對金屬絡合物材料在有機太陽能電池中的應用做簡要介紹，探討這些金屬絡合物“結構-性質”之間的關系，并對其未來在有機太陽能電池應用方面的發展進行展望。

Abstract:

Global environment and energy crises have become the severe obstacles to socio-economic development and survival environment of mankind. The development of clean renewable energy to replace traditional fossil fuels has become one of the main focuses of today’s society. Converting solar energy into electricity by solar cells represents one of the most promising ways. Among the various solar cell techniques, organic solar cells have attracted much attention for their advantages in light weight, wide range, low cost of raw material sources, good mechanical flexibility, and easy wet-processing for large-area devices. The key to further improve the power conversion efficiency of organic solar cells is developing high-performance electron donor and acceptor materials as well as interfacial materials. Among the organic semiconductors, metal complexes have received considerable research interests owing to their high triplet populations, long exciton lifetimes and high fluorescence quantum yield. In recent years, more and more metal complex-based organic semiconductors have been applied in the field of organic solar cells and obtained high device performances. This review briefly introduces the recent applications of metal complexes in organic solar cells from four aspects of electron donors, electron acceptors, additives and interfacial materials. The “structure-property” relationship of the metal complexes is discussed, and their futural development is also prospected.
