英文摘要	thermal stability has been the important issue in organic solar cell, especially for the large scale fabrication and application in the future. in this work, a new strategy involving the introduction of porphyrin compound (bl) is proposed to prevent the [6,6]-phenyl c61 butyric acid methyl ester (pc61bm) aggregation. the supramolecular interactions between pc61bm and bl are first demonstrated in pc61bm:bl binary blend, and then the effect of bl on p3ht:pc61bm blend is qualitatively and quantitatively studied by differential scanning calorimetry, uv-vis absorption spectroscopy, atomic force microscopy, optical microscopy, and fluorescence techniques. it is found that the bl addition not only stabilizes the morphology of p3ht:pc61bm blend films, but also shows a good ability to maintain the electron mobility by depressing the pc61bm crystallization. and the thermal stability of the devices based on p3ht:pc61bm:bl ternary blend films is therefore greatly improved. for example, 8 wt% bl doping drops the power conversion efficiency by 10.5% relative to its peak value after 48 h of annealing at 130 degrees c, while 71.5% of decrease is obtained for the device without bl after only 3 h of annealing. this strategy is preliminarily proved to be universal and will show great potentials in future commercialization of polymer solar cells.
