【摘要】：使用兩種或者更多種類的富勒烯衍生物作為受體可以使poly(3-己基噻吩)(P3TH)系的混合異質(zhì)結(jié)太陽(yáng)能電池效率明顯提升。這樣的提升源于當(dāng)受體使用富勒烯多重加合物的最低未占軌道(LUMO)提升而使其開路電壓升高。雖然其他聚合物也同樣能獲得高的開路電壓,但是大多數(shù)的聚合物卻不像P3TH一樣獲得性能提升,在與像苯基-C61-丁酸甲酯(bis-PCBM)或者the indene-C60 bis-adduct(ICBA)混合后表現(xiàn)出下降的光電流。在此,我們研究這些性能改變的原因。使用[6,6]-苯基C_(70)-丁酸甲酯(PC_(70)BM),ICBA和bis-PC_(70)BM作為受體并且PTB7作為給體,其結(jié)構(gòu)為:ITO/PEDOT:PSS/活性層/LiF/Al,聚合物太陽(yáng)能電池的表現(xiàn)的性能分別為7.29%,4.92%和3.33%。性能的改變可能主要?dú)w因于不同受體影響器件激子產(chǎn)生和電荷收集。
[Abstract]:Using two or more kinds of fullerene derivatives as receptors can significantly improve the efficiency of hybrid heterojunction solar cells of poly (3-hexylthiophene) (P3TH) system. This ascension results from an increase in open-circuit voltage when the receptor uses the lowest unoccupied orbit (LUMO) of the fullerene multiplex adducts. Although other polymers can also obtain high open-circuit voltage, most polymers do not improve their performance like P3TH, and exhibit decreased photocurrent when mixed with methyl phenyl -C61-butyrate (bis-PCBM) or the indene-C60 bis-adduct (ICBA). Here, we study the causes of these performance changes. [6] -phenyl C _ (70) -butyrate methyl ester (PC70BM) and bis-PC70BM were used as the receptors and PTB7 as the donor. The structure of the polymer solar cells was as follows: t / ITO / PEDOT: PSS/ active layer / LiF / Al, the performance of the polymer solar cells was 7.294.92% and 3.33%, respectively. The change in performance may be attributed to the effects of different receptors on exciton generation and charge collection.
