摘要:

全球性的環(huán)境與能源危機(jī)已成為可持續(xù)發(fā)展必須面臨的重要問(wèn)題，開(kāi)發(fā)清潔可再生能源以替代傳統(tǒng)化石能源成為當(dāng)今社會(huì)關(guān)注的焦點(diǎn)之一。其中，利用太陽(yáng)能電池將太陽(yáng)能轉(zhuǎn)化為電能是清潔可再生能源領(lǐng)域最有前景的解決方案。在眾多太陽(yáng)能電池技術(shù)中，有機(jī)太陽(yáng)能電池因具有質(zhì)量輕、原材料來(lái)源廣泛、成本低、機(jī)械柔性好、可采用濕法制備成大面積器件等優(yōu)勢(shì)而備受關(guān)注。開(kāi)發(fā)高性能的電子給、受體材料以及界面材料是進(jìn)一步提升有機(jī)太陽(yáng)能電池光電轉(zhuǎn)換效率的關(guān)鍵。其中，金屬絡(luò)合物因其較高的三線態(tài)激子密度、較長(zhǎng)的激子壽命以及較高的熒光量子產(chǎn)率而引起廣泛的研究興趣。近年來(lái)，金屬絡(luò)合物材料越來(lái)越多地被用在有機(jī)太陽(yáng)能電池中，并使器件獲得了較高的性能。從金屬絡(luò)合物的給體材料、受體材料、添加劑以及界面材料4個(gè)方面對(duì)金屬絡(luò)合物材料在有機(jī)太陽(yáng)能電池中的應(yīng)用做簡(jiǎn)要介紹，探討這些金屬絡(luò)合物“結(jié)構(gòu)-性質(zhì)”之間的關(guān)系，并對(duì)其未來(lái)在有機(jī)太陽(yáng)能電池應(yīng)用方面的發(fā)展進(jìn)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.
