C70苄基衍生物的合成及其在钙钛矿太阳能电池中的应用

富勒烯及其衍生物具有高的电子传输效率,是倒置平面异质结钙钛矿太阳能电池器件中优异的电子传输层材料（electron transport materials, ETMs）。其中,富勒烯C70通常存在众多的异构体产物,通过常规的手段难以实现有效分离,故关于结构明确的富勒烯衍生物对钙钛矿太阳能电池的影响,目前尚缺乏系统的研究和理解。本文基于对一种结构明确的C70衍生物2,5-（PhCH2）2C70的成功合成和分离,并将其作为电子传输材料构建平面异质结倒置太阳能电池器件,最终实现了12.77%的光电转换效率,通过对富勒烯衍生物中分子的晶体结构堆积的研究,分析富勒烯衍生物结构对钙钛矿太阳能电池器件性能的影响。该工作对于拓展和丰富富勒烯衍生物在钙钛矿电池中的应用有着重要的意义。国家重点基础研究发展计划(973计划)(2014CB845601,2015CB932301);;\n国家自然科学基金(21771152,21721001,21390390,51572231,21701134);;\n福建省科技厅高校产学合作项目(2016H6023);;\n中央高校基本科研业务费(20720170028,20720160084

High LUMO energy level C60(OCH3)4 derivatives:Electronic acceptors for photovoltaiccellswithhigheropen-circuitvoltage

E-mail Addresses: [email protected] regioselective C-60(OCH3)(4) derivatives, C-60(OCH3)(4)-PCBM (a methanofullerene derivative of C-60(OCH3)(4), PCBM=[6,6]-phenyl-C-61-butyric acid methyl ester) and C-60(OCH3)(4)-APCBM (an aziridinofullerene derivative of C-60(OCH3)(4)) were synthesized from C60Cl6 and used as acceptor for polymer solar cells. Revealed by cyclic voltammetry, the LUMO energy levels of C-60(OCH3)4-APCBM and C-60(OCH3)(4)-PCBM are 0.2 and 0.3 eV higher than that of PCBM, respectively. For the polymer photovoltaic cells with fullerene (PCBM, C-60(OCH3)(4)-APCBM or C-60(OCH3)(4)-PCBM) acceptor in combination with poly(3-hexylthiophene) (P3HT) donor, the open-circuit voltage is increased from 0.58 V (for PCBM) to 0.63 V (for C-60(OCH3)(4)-APCBm) and 0.72 V (for C-60(OCH3)(4)-PCBM). The higher open-circuit voltages are reasonably attributed to the higher LUMO levels of the C-60(OCH3)(4) derivatives because of four electron-donating methoxy groups attached. The photovoltaic performance of C-60(OCH3)(4)-PCBMbased device is higher than that involving C-60(OCH3)(4)-APCBM, largely due to the structural changeability of C-60(OCH3)(4)-APCBM resulting from the rotatable N-C bond bridge therein. This work demonstrates that fullerene derivatives with higher LUMO level can be functionalized from multiaddition of electron-donating groups, and exemplifies that photovoltaic performances of fullerene-based solar cells are sensitive even to trivial bridge between functional group and fullerene core.

Xiamen Univ, Sch Life Sci, Xiamen 361005, Peoples R China 电子邮件地址: [email protected]; [email protected] hydrofullerene C50H10 is synthesized by low-pressure benzeneoxygen diffusion combustion. The structure of C50H10 is identified through NMR, mass spectrometry, and IR and Raman spectroscopy as a D5h symmetric closed-cage molecule with five pairs of fused pentagons stabilized by ten hydrogen atoms. UV/Vis and fluorescence spectrometric analyses disclose its optical properties as comparable with those of its chloride cousin (C50Cl10). Cyclic and square-wave voltammograms reveal that the first reduction potential of C50H10 is more negative than that of C50Cl10 as well as C60, with implications for the utilization of C50H10 as a promising electron acceptor for photovoltaic applications.973 projects 2011CB935901 NSFC 21031004 21021061 2077310
