The field of organic electronics has been significantly growing during last two decades. In particular, semiconducting (conjugated) polymers have been widely employed as an active layer for various optoelectronic devices. Recently, organic solar cells have attracted keen interest owing to their great potential in pursuit of cheaper renewable energy conversion sources of solar energy to electrical energy. Blends of regioregular poly(3-hexylthiophene) (P3HT) and 6,6-Phenyl-C61-butyric acid methyl ester (PCBM) have demonstrated efficient photogeneration of mobile charge carriers, which could be enabled by controlling the nanomorphology of the bulk heterojunction structure. In this work we report a series of optimized organic solar cells based on blend films of P3HT and PCBM. In particular, we discuss on the limiting factors that affect the performance of multilayer organic solar cells. |
